MESSAGEFROM THEPRESIDENT

Hello, I would like to start off by thanking our 2008 OTF President,

Todd Voss, and all the board members for their time, effort, and vision

they have put into the Ohio Turfgrass Foundation not only this year,

but the past several years in which a number of them have served

on the board. In particular, I would like to recognize Mark Jordan and

Mark Grunkemeyer, who are leaving the board after many years of

service. They both have done a tremendous job in several areas of

OTF and we are a better place because of all of their efforts.

I would like to thank all of those who attended the conference and

show this past year. We had an increase in attendees from the

previous year and we hope this trend continues, even with these

difficult economic times. You can be assured that OTF is cognizant

of these economic challenges and will give you the best education

and show for your value. While we are not as large as other National

Conferences and Shows, we can guarantee you our education and

overall trade show is well worth the investment and time.

I would like to thank you the members, vendors and the companies

that support and sponsor several of our events. Without all of you,

OTF would not be possible.

I want to thank the Ohio State University and in particular, the OSU Turf

Team. These individuals give us a great deal of time and effort, and

provide several of the seminars and educational tracks throughout

the season. Additionally, thanks to Matt Williams and the individuals

who run the Research Facility. Finally, special thanks to our Director

of Education, Dr. John Street and Executive Director, Kevin Thompson

of Offinger Management.

As you are all aware, 2008 has been headlined by the economy, or

the lack of. I am certain every agency, company, or institution that

you manage or are involved with has been affected in some way,

and OTF has been part of the same economic downturn as everyone.

3

You can be assured that the board of directors is doing their best to

ensure that the funds that we have are being used as prudently as

possible, and we will continue to use forward and proactive thinking

in the years to come to ensure that we remain stable during these

difficult economic times.

While the conference and show is one of the best regional

conferences, if not the best conference in the country, we are

constantly looking for attendee and vendor feedback so the show

can evolve into the best it can be each year. From time to time

you will see changes in the show and rest assured that we have

researched and have thoroughly gone over all options before

making any changes. We hope that you agree with us that these

changes are always for the best, and will help keep OTF on the

cutting edge of the Turfgrass Conference and Shows.

Shortly, you will be seeing the release of the Economic Impact

Survey that the Ohio Turfgrass Foundation funded through the

2008 season. This was a large undertaking, and without allied

chapters and other organization’s support, we would be unable to

put this Economic Impact Study together. Please take time to read

and pass this along to your employers so they understand what a

commitment this industry has to the state of Ohio and the overall

agricultural development.

Finally, I would like to recognize some of the individuals that have

helped me progress in the turfgrass industry since my graduation from

OSU/ATI in 1987. These past Superintendents who I have worked for

include; Dennis Krueger (Briarwood G.C.), Bill Risch (Groveport C.C.),

Greg Goedde (Moundbuilders C.C.), and Charlie Engster (Blue Ash

G.C.). Each of these individuals helped in different facets of my career

and gave me the tools, resources and understanding of OTF and how

important it is to support the Green Industry.

I would also like to thank my current employer, The City of Blue Ash,

for their commitment and support during the past several years as an

OTF board member and this current year as OTF President.

Good luck as we head into the spring and summer months.

Dan Walter, 2009 OTF President

The 2008 Ohio TurfgrassConference & Trade Show was THE Place to be for Turf and LandscapeProfessionals

OTF recently announced a 10% increase in attendance figures at

the 2008 Ohio Turfgrass Conference & Show over the 2007 event.

The 42nd annual event was held December 8 – 11 in Columbus

treated to over 120 hours of educational sessions and a trade

show featuring over 350 booths from nearly 200 leading turfgrass

suppliers.

The Ohio Turfgrass Research Trust (OTRT) raised more than $17,000

at its auction thanks to all the vendors and members who donated

time, products and generosity. The Live Auction continues to raise

funds to support scholarships and research funding for OTRT.

During a brief program before this year’s keynote speech, OTF

Al Turgeon, Penn State University, gave this year’s Keynote Speech

– “Implications of Global Warming: Cultural Relief and Future

Management Strategies”.

An exciting addition to this year’s conference was the 3rd Annual

Ohio Golf Summit, hosted by Play Golf Ohio. Highlights of the

summit included a review of Play Golf Ohio’s Economic Impact

study, discussion on enhancing the working relationship between

golf’s allied associations and facilities in Ohio, the sharing of ideas

for positively impacting the game of golf in Ohio, and multiple

presentations by golf’s industry leaders, including Steve Mona,

CEO, World Golf Foundation; Mark Woodward, CEO, Golf Course

Superintendents Association of America; Charlie Birney, President,

National Golf Course Owners Association; Jim Singerling, CEO, Club

Managers Association; and Keynote Speaker Joe Steranka, CEO, PGA

of America.

Allied organizations, including the Ohio Lawn Care Association,

Ohio Sports Turf Managers Association, and Ohio Sod Producers

Association held their annual meetings in conjunction with the

conference and show. The collaborative relationship among these

allied industry groups, along with the Ohio Chapters of the GCSA, help

make Ohio’s turfgrass industry what it is. Many thanks to the trade

show committee of Joe Enciso (chair), Chad Allen, Don Botkin, Mike

Dietrich, Bill Easterday, Mark Jordan, Alan Mark, Scott Robinson,

Ted Shackleford and John Street.

The Program Development Committee earned high praise for

developing a great educational program giving turf professionals the

opportunity to learn the latest in turfgrass management practices

while earning valuable CEU credits. The Program committee is

chaired by Dr. John Street, co-chairs Doug Gallant, Kim Kellogg and

Todd Voss, and committee members Bob Becker, Kyle Frederick,

Dr. Dave Gardner, Deb Holdren, Pam Sherratt, Dr. Dave Shetlar, Don

Sutton, Micke Takach and Joe Rimelspach.

Thanks to all committee volunteers for its guidance and organization

of this great event! The plans are already underway for the 2009

Ohio Turfgrass Conference & Show. Mark your calendars now for

December 7 – 10 in Columbus.

NEWSLive Auction GeneratesMore than $17,000

The Live Auction held at the 2008 Ohio Turfgrass Conference & Show

raised more than $17,000 for turfgrass research and scholarships.

The funds generated by the auction support the Ohio Turfgrass

Research Trust (OTRT), the charitable fund-raising arm of OTF.

The auction was held in the convention center following the close

of the trade show on Wednesday, December 10. Several hundred

people gathered to view and bid on the many great items donated by

OTF members and exhibitors.

In addition to the Live Auction was the Reverse Raffle. OTRT and OTF

volunteers sold raffle tickets at $20 each throughout the first 2 days

of the show. Winners were selected to receive cash prizes, along

with a Grand Prize winner of $1000.

Several great items were sold at bargain prices at the auction,

including autographed sports memorabilia, rounds of golf at many

of Ohio’s exclusive golf courses, a night with the Cincinnati Reds

Grounds Crew, a John Deere mini-gator, turf equipment, supplies

and more. Two sets of tickets to the Fiesta Bowl generated more

than $2200!

The goal is to continue growing the auction so that more than

$20,000 is raised by the 2009 auction committee, which will be

working hard throughout the year soliciting donations from OTF

members and suppliers.

A special thanks to committee chair Joe Enciso, Todd & Heidi Voss,

and Don Lawrence for helping organize and run the auction and

reverse raffle. On behalf of the Ohio Turfgrass Foundation and the

Ohio Turfgrass Research Trust, thanks to everyone who participat-

ed and especially to the donors (see page 7) of this year’s auction.

They proved that raising funds for turfgrass research can be fun!

First Ohio TurfgrassAlumni Social Gatheringa Big Success

A new addition to the Ohio Turfgrass Foundation conference and

show in 2008 was the Ohio Turfgrass Alumni Association Social

Gathering. This event and group was organized by Gina Zirkle, a

2004 OSU Alumni, and Research specialist at The Scotts Company,

with help from Joe Enciso of Advance Sensor Technologies and

Matt Williams of Ohio State.

The Organization was formed in 2008 as a group to help turfgrass

alumni from the state of Ohio stay connected. The first event was a

social gathering held in the basement of Barley’s across the street

from the convention center. The Event was sponsored by The Scotts-

Miracle Gro Company and Advance Sensor Technologies, and would

not have been possible without their support. About 80 people showed

up for the first event. There was some light food and beverages,

but more importantly there were friends. The purpose of the event

was to have a venue in which the attendees could get together and

just socialize. There is so much to do at the OTF conference, from

education to the trade show, the auction, corporate parties and so

on, sometimes just getting together with old friends gets over looked.

“We wanted to organize an event with the sole purpose to socialize

with old friends, former classmates, and industry professionals” said

Gina Zirkle. “We also wanted to see what interest’s people would

have in such an organization.”

There was no charge to attend the social gathering. Alumni had

the opportunity to join the association for $15, and a Jim Tressel

Autographed football was auctioned off to raise money for the

association. With the success of the Social Gathering, and a clear

demand for a way to stay connected with alumni and friends within

the industry, the group has planned to repeat the social gathering

at the 2009 OTF conference as well as offer other networking

opportunities, including developing a website and a newsletter that

will highlight Ohio Turfgrass alumni activities. If you would like to help

with the growth of the Ohio Turfgrass Alumni Association, please

contact Gina Zirkle at Gina.Zirkle@scotts.com or Matt Williams at

williams.1278@osu.edu.

Bernhard and Co. Makes Significant Donationto Turfgrass Research Facility

Bernhard and Company, manufacturers of Express Duel and Anglemaster reel and bedknife grinders, in cooperation

with Reynolds Golf and Turf Equipment, have loaned their reel and bedknife grinding system to the OTF/OSU

Turfgrass Research and Education Facility. In a unique partnership, the research facility will have the machines

available for maintaining the twenty plus cutting units that are used at the facility to mow the research plots.

In addition, OSU plans to add cutting unit theory and maintenance to its education program. Dr. Karl Danneberger,

Professor in the Department of Horticulture and Crop Science said “Reel and bedknife maintenance is a complicated subject that

has an enormous impact on turfgrass quality. Our students traditionally have not been exposed to this in the classroom or in the field

before they graduate, so this donation gives our students the chance to learn the basics of reel sharpening and operation.”

“There are so many uses for grinders in education,” says Stephen Bernhard, owner of Bernhard and Company.

“It is important for students to understand the implications of developing a sharpening program and how it relates to turf health,

appearance and playability. We look forward to a long-standing relationship with OTF and The Ohio State University.”

Representatives from Bernhard and Co. and Reynolds Golf and Turf were at the research center recently installing

and training facility management on the new machines. If you or your company is interested in making a donation in

the support of research and education at Ohio State please contact Matt Williams, williams.1278@osu.edu.

GRADUATE STUDENT SPOTLIGHTJohn koenig – Plant Pathology

John Koenig graduated from The Ohio State University with a major in Turfgrass Science and a minor in Agricultural Business in 2006. During

his time at Ohio State he was an active member of the OSU Turf Club, participating in the STMA and GCSAA turf bowls and was elected as the

Liaison/ Head of Marketing in 2004 and Vice President in 2005, receiving several outstanding student achievement awards.

His education and work experience at The Ohio State University Athletic Field Maintenance Department, Sylvania Country Club, and Kirtland

Country Club and volunteer work at Columbus Crew Stadium has led to a career path that he knows will bring challenges and great satisfaction.

To cap his formal academic career, he is pursuing a master degree in Turfgrass Pathology under Dr. Mike Boehm and will be graduating in 2009.

His research objective is to determine the relationship between climatic conditions and pathogenicity of Sclerotinia homoeocarpa to optimize

fungicide efficacy. In 2006 and 2007 replicated field studies were established at two locations in central Ohio to determine the relationship

between climatic conditions and the ideal moment for making preventive fungicide applications. Weather monitoring stations were installed

at both locations to record on-site soil moisture, soil temperature, air temperature, precipitation and relative humidity amounts. Sequential

applications of propiconazole and chlorothalonil as a combination treatment were applied to asymptomatic fairway turfgrass in the fall of 2006,

spring of 2007 and in the fall of 2007 through July 1, 2008. Disease severity was quantified as the number of dollar spot infection centers and

percent of dollar spot symptoms per plot using a self-illuminating box specially constructed specially for this project and the APS Press’s Assess

Image Analysis software for plant disease qualification. Data was recorded through July of 2007 and 2008 to calculate area under disease

progress curves for each treatment and data collection method. Data from this study was presented at the Ohio Turfgrass Foundation’s field

day, The American Pathological Society’s conference in Minneapolis Minnesota, The Joint 5 Agronomy Meetings in Houston, Texas and the Plant

Pathology Seminar series at Cornell University. To receive an update on his research please contact John at koenig.254@osu.edu.

NEWGROWTH &TECHNOLOGy

As spring approaches it becomes important to begin thinking

about your turf weed control programs. Remember that the first

step to controlling weeds is to identify which weeds are present

on a site. Proper identification of the weed will assist with two

things: 1) selecting the correct herbicide and 2) applying that

herbicide at the right time in the weed’s life cycle in order to

maximize control.

If you are primarily dealing with annual broadleaf weeds (tables

1a or 1b) then you can control these possibly with a preemergence

herbicide (check the label of your crabgrass control product) or

postemergence. The issue with using a preemergence herbicide

is usually one of timing. For example, knotweed germinates in

late March, before we recommend application of preemergence

herbicides. Late germinating weeds, such as oxalis, germinate very

late, after most preemergence products have lost effectiveness.

However, the preemergence herbicide will provide some defense.

Always check the label and remember to target the application

for crabgrass control, making the application sometime in April

when Forsythia are in bloom. If you have some breakthrough then

postemergence products are very effective. However, you will

want to target the weeds early in their life cycle, before they have

the chance to set seeds that will become next year’s infestation.

Use tables 1c and 1d to determine if you have perennial broad-

leaf weeds and when the most appropriate time to control them

is. Usually fall time applications are recommended for perennial

broadleaf control. If you make a springtime application (and

most do for obvious reasons) then know that this is going to be

effective probably for 60-90 days depending on the product used

and the rate applied. Broadleaf weeds, whether new or regrowth

from below ground structures on the surviving original weeds, will

reappear. Fall applications tend to result in longer term control due

to more complete translocation into below ground weed parts. If

you see weeds this fall, consider making an application with an

ester formulation of an herbicide recommended in table 2.

After determining your target weeds then use table 2 to select

the best herbicide for the application. Table 3 includes a list of

combination herbicides which are commonly applied in order to

broaden the spectrum of control on sites with multiple weeds

species. Always read the label prior to use of a herbicide. Be

particularly mindful of the reseeding interval if any renovation

work is planned, susceptible weed species and the site and or use

restrictions of the product.

new herbicide Formulations

Several new herbicide formulations or active ingredients have

been released for use in turf during the past few years. There

seem to be three major trends with the emergence of these new

herbicides. The first is that many of these materials promise to

allow the turf manager selectivity, particularly with perennial

grass weed control, that even five years ago we would not have

thought possible.

These new herbicides are bispyribac-sodium (Velocity®), me-

sotrione (Tenacity®) and sulfosulfuron (Certainty®). Velcoity pro-

vides some selective control of annual bluegrass. Mesotrione will

selectively control creeping bentgrass. Though not on the label,

mesotrione also has activity on nimblewill and orchardgrass.

Certainty will give some selective control of rough bluegrass.

Consult the product labels for more specifics about timing, rates,

and turf species to which these materials can be applied.

The second trend is that there are many formulated products either

newly released or in various stages of testing that offer “single

application” weed control of both broadleaf and grassy weed

species. Q4® and Quincept® are examples of products intended

to control all weeds postemergence with a single application. Both

combine 2,4-D, dicamba, and quinclorac (the active ingredient in

Drive®). Q4® also contains sulfentrazone and thus has activity

on yellow nutsedge. Quinclorac is of course not new, but BASF

has released a new formulation and increasingly quinclorac is

appearing in combination products, not just for crabgrass control,

but also for broadleaf weed control, particularly clover. Several

other combination products, that will afford both pre and post-

emergence control or broadleaf and grassy weeds with one

application, are in various stages of testing.

Another emerging trend is that with the increased use of granular

herbicides, there has been a significant amount of research into

carriers that more effectively deliver the herbicide to the target

weed. Because of this, granular herbicide technology seems

poised to improve considerably in the next few years. More soil-

active herbicides that are more effective when relying on soil

take-up are being tested. Also, the formulation technology of the

granule is improving to increase the amount of contact between

the herbicide with the foliage.

a. Cultural Control

The most effective control against the establishment of annual

grass weeds in turfgrass is the culture and maintenance of a dense,

healthy stand of turfgrass. This preventative cultural approach is

successful only if proper fertilization, mowing, irrigation, pest control,

etc. practices are implemented in the culture of the turfgrass.

Unfortunately, in many turfgrass areas, the desirable turfgrass fails

to establish sufficient competition to prevent all the germinating

annual grass weeds from establishing and the need for preventative

chemical control results.

The most common annual grass weeds to encroach Ohio’s turfgrass

areas include:

• Crabgrass (Large, Smooth) • Fall Panicum

• Goosegrass • Barnyardgrass

• Yellow Foxtail • Annual Bluegrass (Poa annua)

B. Preemergence Chemical Control

Most turfgrass managers across the state continue to rely on the use

of preemergence herbicides for assistance in the control of annual

grass weeds.

1. Newly Seeded Turfgrass (mowed less than three times)

a) Siduron should be applied at the time of seeding or prior to

the emergence of the weedy grasses. A second application may

be necessary where weed pressure is heavy.

b) Tenacity (mesotrione), a new Syngenta herbicide, can be ap-

plied at the time of seeding for preemergence control of several

annual grasses and broadleafs.

2. Established Turfgrass

a) Preemergence annual grass herbicides for 2008 include:

• Benefin (Balan)

• Bensulide (Betasan, others)

• Pendimethalin (Pre-M, Pendulum, Pendulum Aquacap, others)

• Oxadiazon (Ronstar)

• Trifluralin + Benefin (Team Pro)

• Dithiopyr (Dimension)

• Prodiamine (Barricade)

3. Soil Temperature

The temperatures listed in table 2 refer to the average soil temp-

erature in a 24-hour period over several days. Monitoring soil

temperature (most accurately on site) is one of the best ways to

predict weed germination. In the spring, soil temperatures within

the landscape can vary considerably, with south and west facing

exposures heating up most rapidly. Therefore these areas should be

the main target monitoring sites in the landscape for temperature

and degree-day determinations.

It is also important to note that critical soil temperatures for annual

grassy weed germination vary among species (table 2). Annual

bluegrass, for example, germinates significantly earlier in the spring

(i.e. 45 F soil temperatures) relative to most other annual weedy

grasses. Preemergence herbicides will need to be applied very early

Turfgrass Weed Control and Herbicide Update – 2009Dr. John R. Street, Dr. David Gardner, Deborah Holdren and Pamela J. Sherratt,OSU, Department of Horticulture and Crop Science

23

in the season for maximum efficacy on annual bluegrass. Late fall

applications of preemergence herbicides may be an alternative

approach where annual bluegrass is a key target weed.

4. Degree-days

Another useful method for predicting crabgrass emergence is

phenology. Typically, phenology refers to using temperature as a

basis for predictive methods because plant growth and development

depend on temperature. Fidanza and Dernoden (1996) provided

useful information to predict crabgrass emergence as influenced by

growing degree-days.

By monitoring crabgrass emergence patterns in conjunction with

calculating degree-days accumulation, turfgrass managers can

develop models as a guide for targeting preemergence herbicide

applications in their region. It is important to understand that

biological processes don’t suddenly turn on when a specific degree-

day total is reached but they occur within a range of degree-days. For

example, in Fidanza’s study at the University of Maryland, crabgrass

first germinated within a degree-day range of 42-78.

It is also important to recognize that crabgrass will continue to

germinate and emerge for several weeks after initial crabgrass

emergence is observed. Fidanza reported peak gemination occurred

at 150-225 growing degree-days and then for a considerable time

thereafter.

Therefore, preemergence herbicide applied after the initial germ-

ination period will still provide a significant benefit in preventing

additional crabgrass emergence that occurs before the peak.

However, crabgrass that has germinated most likely will mature and

result in consumer complaints or dissatisfaction. This problem can be

addressed by (1) combining a preemergence with a post-emergence

herbicide if the target date is missed or (2) using a specialty herbicide

like Dimension (table 3) that has pre- and post-emergence activity.

Dimension is the only preemergence herbicide that provides effective

postemergence activity when applied prior to tillering.

5. Calendar Dates

The timing of preemergence herbicide applications is the most

critical component of an effective chemical control program. As a

general rule, apply preemergence herbicides one to two weeks prior

to crabgrass seed germination in the early spring. Typically, crabgrass

germination and emergence in Columbus occurs between April 20

and 25. Normally, target dates for making preemergence crabgrass

treatments in Ohio are:

Northern Ohio April 1 – May 1

Central Ohio March 15 – April 15

Southern Ohio March 1 – April 1

It is a sound agronomic strategy to apply the preemergence herbicide

a little earlier in the spring than to delay the application and miss the

target date window. Remember, improper timing is considered one of

the major reasons for preemergence herbicide failures.

Irrigation or rainfall with approximately 1/2" water within several days

after a preemergence herbicide application is critical for maximum

effectiveness. Irrigation/rainfall serves to move the herbicide off of

the turf foliage and/or fertilizer granule and into the zone of influence

(1-2" of the soil surface) where the herbicide becomes active.

Remember, the crabgrass seed is germinating in the soil and it is

when the seedlings are emerging (growing toward the soil surface)

that contact with the herbicide is made. Preemergence herbicides do

not affect ungerminated (dormant) seed.

Degree-days refers to the accumulation of temperature over time

and it dictates the rate of growth and development of plants and

organisms. Below a certain temperature plants are essentially

dormant and growth and development stops. This temperature is

referred to as the base temperature. For most organisms the base

temperature is 50 F.

Degree-day accumulation is the sum of the number of degrees

(degree-days or degree-day units) by which each day’s average

temperature exceeds the base temperature; and it is easy to

calculate. One degree-day is equal to 1 degree above the base

temperature in a 24-hour period. (See calculating degree-day

accumulations chart for a more detailed explanation).

You calculate degree-days daily and summarize them over time

beginning on a specific starting date. Fidanza used soil temperature

at the 1" depth to calculate degree-days since it correlated well with

smooth crabgrass emergence in the study.

continued on page 24

24

continued from page 23

Over the 3-year period smooth crabgrass first emerged when

minimum soil temperatures averaged 54 F, which was used as the

base temperature.

The proper rate and uniform distribution of the preemergence

herbicide is also critical to insure good efficacy. A certain con-

centration of each preemergence herbicide must be maintained

in the upper soil zone at the threshold level during the active

germination period for season-long control.

Improper distribution, improper rate, and improper pattern overlap

can allow for weak spots in the surface chemical barrier that may

result in concentration of the herbicide dropping below the threshold

level allowing for short and long term (residual) failures. These

factors are also ranked high on the list of reasons for preemergence

herbicide failure.

Finally, agronomic programs that are consistently exhibiting short

term or long term preemergence herbicide efficacy failures should

carefully check rate and application accuracy, up the preemergence

rate more to the upper end of the range, or utilize a follow-up

sequential application at half rate (Ohio). In OSU research for

example, pendimethalin and benefin/trifluralin provide better and

more consistent efficacy at 2 lb a.i./acre than at 1.5 lb a.i./acre.

C. Postemergence Chemical Control

After annual grassy weeds have established in turfgrass areas, their

removal usually necessitates the use of postemergence control

products. The herbicides available for postemergence annual grassy

weed control in 2009 include (table 3):

• Fenoxaprop p-ethyl (Acclaim Extra)

• Dithiopyr (Dimension)

• Quinclorac (Drive)

• Tenacity (mesotrione)

Dimension is unique in that it exhibits both preemergence and

postemergence activity on crabgrass. It is most efficacious on young

crabgrass that is not beyond the 1-2 tiller maturity stage. Growth

stoppage of crabgrass occurs within 3-5 days after application but

actual kill takes 3-5 weeks. It is a good specialty herbicide for use

where the critical target date for crabgrass germination has been

missed, a postemergence application is required, but seasonal

preemergence control is still necessary.

Tenacity will effectively control crabgrass postemergence. The

label states that 2 applications are required. In 2008 OSU research,

Tenacity provided good-excellent postemergence crabgrass control

with one application prior to tillering. A combination of Tenacity

and a standard preemergence (i.e. Barricade ) will allow early post

control of non-tillered crabgrass and season-long pre control with

one application. Additional research is being conducted at OSU on

Tenacity efficacy on tillered crabgrass at various herbicide rates and

maturity stages.

Drive continues to be a good to excellent postemergence herbicide

for crabgrass control. It does appear to provide some variability

in efficacy/control in the intermediary crabgrass maturity stage

of approximately 2-4 tiller at times. OSU research is continuing to

evaluate approaches to address this variability issue. BASF has

released a new formulation of Drive called Drive XLR8 that causes

more rapid crabgrass discoloration following application and in our

2008 OSU research possible enhanced efficacy at the intermediate

crabgrass maturity stage. This research will continue in 2009. The

inclusion of sulfentrazone (Dismiss) with Drive to enhance efficacy

has resulted in mixed/variable results to date in our OSU research

trials.

a. Cultural Control

The same preventative cultural controls recommended for addressing

annual grass weeds also apply to broadleaf weeds. A sampling of

broadleaf weeds commonly found in Ohio’s turfgrass areas include:

• Dandelion • Common chickweed

• White clover • Yellow wood sorrel

• Buckhorn plantain • Ground ivy

• Common plantain • Black medic

B. Preemergence Broadleaf Chemical Control

Gallery, a Dow AgroScience’s product introduced in 1989, continues

to be the only commercially available herbicide labeled for broadleaf

weed control in turfgrass. Recommended turfgrass use rate is 0.75

- 1.00 lb a.i./acre. Season long control requires the application

of both spring and fall treatments. Gallery has no postemergence

activity on broadleaf weeds.

C. Postemergence Broadleaf Chemical Control

1. Broadleaf Weed Control on Newly Seeded Turfgrass (new turf-

grass mowed fewer than three times)

a) Bromoxynil (Buctril) is available for use in nonresidential

areas. Seedling turfgrass product use rate is 1.0 - 2.0 pt/acre.

Pest weed control is achieved if the weeds are less than 2" tall

when treated.

b) 2,4-D can safely be used on young turfgrass provided the turf-

grass has been mowed at least thee times and the use rates do

not exceed 1.0 lb a.i./acre.

c) There traditionally have been two products labeled for control

of weeds in newly seeded cool season turf: siduron and brom-

oxynil. Neither of these products are as effective as other herb-

icides used in established cool season turf but their safety to

turfgrass seedlings makes them a good option. However, research

conducted at major universities has concluded that a recent

introduction, carfentrazone (marketed as Quicksilver by (FMC),

provides safe and effective control of germinating broadleaf

weeds in a newly seeded stand of either Kentucky bluegrass

(Poa pratensis) or perennial ryegrass (Lolium perenne).

The label for Quicksilver has been updated to allow application

to these species seven days after emergence. Carfentrazone is a

fast acting contact herbicide that has been recommended as an

additive to systemic herbicides, such as 2,4-D or triclopyr, in order

to hasten burndown of the weed. It is important to note that since

carfentrzone is a contact herbicide, it will be effective for the control

of germinating annual broadleaf weeds in a newly established turf.

However, it will not be as effective if used against mature broadleaf

weeds during an overseeding operation.

Another promising development for springtime weed control at est-

ablishment is with quinclorac (marketed Drive). Quinclorac is labeled

for application any time before or after establishment of tall fescue.

continued from page 25

And research shows that quinclorac can safely be applied to either

Kentucky bluegrass or perennial ryegrass as little as 7 days after

seedling emergence. The labeled suggests restricting the use on

seedling turf to 30 days after emergence.

Results of research recently conducted at The Ohio State University

also indicate that not only can a combination of quinclorac and

carfentrazone be applied to 7 day old seedlings of either of these

species, but that delaying the application to 14 or 21 days after

emergence actually results in decreased weed control. This is likely

because the herbicides become less effective as the weeds become

more mature and capable of competing with the germinating turfgrass.

There was some slight phytotoxicity with the 7 day application, but

the turf outgrew this by day 14.

2. Broadleaf Weed Control on Established Turfgrass

The list of postemergence broadleaf herbicides for use in establish-

ed turfgrass and their herbicide class are provided in table 4.

The new Confront label does not allow for use on residential turf. It

is permitted for use in other turfgrass areas (i.e. golf courses and

sports fields). The label restriction is due to the presence of carryover

of clopyralid residues in clippings and compost. The substitute for

clopyralid is fluroxypyr, sold alone as Spotlight and in combination

as Escalade.

Other recent changes in herbicide formulations are the addition

of carfentrazone and sulfentratzone in low concentrations in

combination herbicide formulations for more rapid discoloration of

broadleaf weeds. Carfentrazone combos include Speedzone and

Powerzone and a sulfentrazone combo is Surge. Octane pyraflufen-

ethyl) from SeaPro is a new contact herbicide presently being used

in a manner like carfentrazone. It is in the same chemical family

as carfentrazone – the sulfonylureas. See table 4 for all broadleaf

weed combination options.

Tenacity (mesotrione) has recently been labeled for postemergence

control of a wide variety of broadleaf weeds. There are presently

35-40 broadleafs listed on the label (see label for susceptible

weeds). Tenacity can also be used for pre and postemergence

activity on summer annuals like oxalis and spurge in newly seeded

turf situations.

It continues to only have an approved label for golf courses and sod

farms, but Syngenta is continuing active labeling for lawns/grounds.

Postemergence treatments on established turf usually require a

second application at a 2 to 3 week interval and it is not suggested

that the interval be shortened, especially on perennial ryegrass.

Apply to young actively growing weeds with a NIS type surfactant

for best results.

Tenacity is a systemic preemergence and postemergence herb-

icide for the selective contact and residual control of weeds in

turfgrasses. It is in the triketone herbicide family and functions

as a pigment inhibitor. This results in a temporary whitening or

bleaching appearance to the target weed foliage. In general,

symptoms appear 5 to 7 days after application and last for several

weeks prior to weed necrosis.

iii. PeRennial gRaSS WeeD COnTROl

Perennial grassy weeds continue to be a major weed problem for

many turfgrass managers across Ohio. The problem lies in the

control/removal of these undesirable grass weeds. A few of these

grass weeds include:

• Tall Fescue (growing in clumps) • Nimblewill

• Bentgrass (as a contaminant) • Quackgrass

• Poa trivialis (rough bluegrass) • Orchardgrass

a. non-Selective, Systemic Controls

Glyphosate (Roundup Pro) and Glufosinate ammonium (Finale) are

the two primary nonselective systemic herbicides used in turfgrass

management. Roundup Pro is a Monsanto product and is a com-

bination of glyphosate and a surfactant. A new Monsanto Roundup

formulation called Roundup Pro Maxx will also be available in 2009.

Glufosinate ammonium (Finale) is a product of Bayer. Finale, like

Roundup Pro, has some systemic activity, is foliar absorbed in 2-4

hours and has no soil residual activity.

Visual effects from Finale applications are expressed in 2-4 days after

application. The speed of initial discoloration following applications

of Roundup Pro and Finale can be further enhanced with the addition

of nonselective contact herbicides such as Scythe or Reward.

Glyposate has also been formulated for more rapid burndown of

weeds in QuickPro. QuickPro discolors weeds in two-three days.

27

B. Selective Controls

1. Tall Fescue Control

The Riverdale product, Corsair (active ingredient – chlorsulfuron),

continues to be available for selective tall fescue control in

established Kentucky bluegrass. This product should not be used

on perennial ryegrass. The new Monsanto product, Certainty (active

ingredient sulfosulfuron) is available for selectively removing tall

fescue from Kentucky bluegrass. Check the label for rates and

species precautions. The potential for stunting, discoloration, and

injury to Kentucky bluegrass and perennial ryegrass has resulted in

limited use in the latter species.

2. Creeping Bentgrass Control

The new Monsanto product, Certainty (actual ingredient – sulfo-

sulfuron), is available for selectively removing rough bluegrass

from creeping bentgrass when summer applied.

The new product from Syngenta, Tenacity (active ingredient mes-

otrione), is also available for selectively removing creeping bentgrass

from Kentucky bluegrass. It requires multiple applications and

provides good safety on Kentucky bluegrass. It also has activity on

a number of other annual grasses and broadleaf weeds (check the

label). Perennial ryegrass is more sensitive to Tenacity than Kentucky

bluegrass. Two to three sequential applications are required based

on use rate for optimum control and the 14-21 day application

interval should be adhered to especially on perennial ryegrass.

3. Annual Bluegrass (AB)

a) Plant Growth Regulators (PGRs)

Syngenta’s Trimmit (paclobutrazol) and Primo (trinexapac-ethyl)

and SeaPro’s Cutless (flurprimidol) are all gibberellic acid synthesis

inhibitors and all cell elongation inhibitors capable of assisting in

the suppression of annual bluegrass and the conversion to a more

desirable species. They are also being used at lower rates to

reduce seedstalk length for enhancement of golf playability. Primo

MAXX is a foliar absorbed PGR used more at lower rates to provide

color and quality enhancement rather than AB control. Cutless and

Trimmit are used in CB/AB conversion programs in a variety of

rate frequency programs from traditional heavy rate spring-fall

programs to lighter rate spring-summer-fall programs, and a

combination of the latter.

Embark T/O and Embark Lite (melfuidide) are used for growth

suppression and seedhead control of annual bluegrass on golf

courses. Caution must be exercised because Embark can cause

phytotoxicity if applied at higher rates and improperly. However, it

is an excellent seedhead suppression PGR as it functions as a

mitotic inhibitor.

Proxy (ethephon), a Bayer product, is being used primarily for

growth suppression and annual bluegrass seedhead suppression

in some locations of the country (e.g. West Coast). Primo/Proxy

combinations have been used in the Midwest but seedhead con-

trol has been variable.

b) Herbicides

Bayer’s Prograss (ethofumesate) is a postemergence herbicide

labeled for eliminating AB from creeping bentgrass, Kentucky

bluegrass and perennial ryegrass. The best efficacy from Prograss

has occurred with multiple applications in the fall. See label for

rates and applications, but it’s a multiple fall application program.

Velocity (bispryibac sodium) is an ALS inhibitor labeled in 2005

by Valent for postemergence control of annual bluegrass in

creeping bentgrass. It is presently not labeled for bentgrass

greens. Velocity will kill annual bluegrass in 4-6 weeks depending

on rate. It is most efficacious and recommended for application

between June 1 and September 15. It produces a banana yellow

flash/discoloration on annual bluegrass and bentgrass in 4-8

days and lasts 14-21 days on bentgrass. AB continues to discolor

and decline with kill occurring in 4-6 weeks or longer depending

on the rate/frequency program. The more frequent/low rate

program (i.e. 10g a.i./acre every 2-3 days) has provided excellent

and most consistent efficacy. Turf can be reseeded ten days after

the final Velocity application.

4. Other Weeds

Yellow nutsedge is a prevalent perennial weed found in many

turfgrass areas in Ohio. This weed is neither a grass nor a broadleaf,

but instead a sedge. Consequently, the annual grass and broadleaf

herbicides have limited impact on this weed. Selective control of

yellow nutsedge in turfgrass areas is limited to the use of Basagran,

Certainty (sulfosulfuron), and Dismiss (sulfentrazone) (see labels

for rates and timings). Again, be cautious on the use of Certainty on

KB and PR. OSU research has shown Dismiss to provide excellent

postemergence yellow nutsedge control.

Sedgehammer (Gowan Co.), previously Manage, is labeled for yellow

nutsedge. It is foliar absorbed and has displayed excellent safety on

all cool-season turfgrass species.

With the cold weather upon us, it’s important to be mindful of the risks

associated with the weather. Although there is no specific regulation

that addresses the protection of workers from environmental cold, the

end result could be very costly. Direct cold related injuries can easily

be prevented and save you money. Hypothermia, frostbite, immersion

foot and chilblain are examples of direct cold related problems.

hypothermia, for example, has a very high fatality rate. This occurs

when the body’s internal temperature drops below 95°F. Hypothermia

is a huge threat in frigid weather but can also strike during moderate

temperatures.

Frostbite occurs when skin, muscle, blood vessels and nerves freeze

and form ice crystals. Blood vessels become blocked with tissue

debris that causes more damage. Frostbite is often irreversible and

amputation is sometimes required. If the injured site heals, the victim

may suffer chronic pain or numbness, excessive sweating, abnormal

skin color and joint pain. This would require long term care and can

cost you a lot of money.

immersion foot can occur during wet or muddy conditions just

above freezing. If any part of the body is covered with the water or

mud, it could become chronically swollen, weak and sensitive to the

cold. Again, this can require long term treatment and continue to

be costly to the employer.

Chilblain is another skin condition that can occur after cold ex-

posure. The symptoms appear on the hands and can include red,

swollen skin that feels hot, tender and itchy.

Taking precautions during winter months can prevent cold related

injuries. Train your employees on proper clothing attire and require the

use of hand, foot, head and face protection in three layers. The middle

layer will serve as an insulator. You should also track the temperature

and air movement and provide warming shelters for your employees.

For additional information on risks and prevention of cold related

injuries, contact RiskControl360° at 1-877-360-3608.

Working Safely During Cold Weather

The Ohio Bureau of Workers’ Compensation’s (BWC) Board of Directors

took action to provide some Ohio employers more time to pay

premiums and allow employers conducting business outside of the

state to reduce their workers’ compensation insurance premiums.

The board approved a rule change for the 50/50 payment program,

which enables Ohio businesses that pay online to split their yearly

premiums into two payments. The change allows businesses to pay

only 50 percent of their premium costs by February 28 and pay the

remaining 50 percent by June 1. Second payments were previously

due by May 1. 17,000 employers currently participate in the program.

“We know that countless of Ohio employers are under tremendous

pressure to meet all of their financial obligations,” said BWC Adminis-

trator Marsha Ryan. “Increased flexibility for employers in meeting their

workers’ compensation obligations will provide immediate relief.”

The board also approved rule changes related to Senate Bill 334,

which went into effect in September, and allows businesses to avoid

premium payment to BWC for work done in other states and covered

by another state’s policy. Generally, the law also requires out-of-state

employers, with employees working in Ohio, to provide workers’

compensation coverage for their workers when they come into Ohio

to perform their duties.

As a result of the rule changes, Ohio employers must report to BWC

the payroll reported to the other state’s insurer. However, they are not

required to pay BWC premium on the other state’s payroll. BWC will

also now recognize the coverage of an out-of-state employer working

in Ohio to the extent that state will honor the BWC coverage for Ohio

employers temporarily working in their state. Out-of-state coverage

will be honored for a period of up to 90 days.

Once employers notify BWC of their Others States coverage, they

can take advantage of this law change when they file their payroll

report and pay their premiums for the Jan. 1 to June 30, 2009 payroll

reporting period.
