Around New YorkStatewide (Tim Martinson)Harvest is starting to pick up This week 13 of our sample blocks (see fruit composition table pp 7-10) with Baco noir Sevyal blanc Vignoles and a few Marquette blocks har-vested Overall total soluble solids are still lower than last yearrsquos (0-3 degBrix lower) but the warm sunny days are help-ing them catch up to last year Overall acids are still run-ning rougly 2 gl higher than last year ndash again except on Long Island where they have had ideal ripening weather Across the state warm dry weather provided ideal ripen-ing conditions

Cold-climate Minnesota cultivars (La Crescent Marquette and Frontenac) range from 20-23 degBrix 2 degBrix behind last year and acids are higher at 13-17 gl ndash 2 gl higher than last year Early hybrids (Marechal Foch and Cayuga) are at harvestable numbers (9-10 gl 18-21 degBrix) while later hy-brids (Vidal Noiret Traminette) have acids dropping sig-nificantly (-15-26 gl from last week but still at 11-13 gl)

Among the natives Niagara is at harvestable levels (169 degBrix up 15 degBrix from last week) and the three Concord blocks are averaging 151 degBrix ndash up +17 from last week but still -21 degBrix lower than last year at this time

Long Island vinifera samples are running at a par or ahead of last year and Sauvignon blanc has been harvested (+26 degBrix higher than last year and -17 gl lower) Cabernet franc from the Island and lower Hudson is above 20deg Brix with acids at 5-65 gl ndash in contrast to Finger Lakes and West-ern new York samples with acids still in double digits (10-119 gl) Similar story with Riesling ndash a gain of 15 deg Brix over last year but acids under 10 gl in the Hudson and Long Island but ~12-15 gl in the Finger Lakes and West

This week we harvested Vignoles from the Lake Erie re-gion that were part of a clonal evaluation comparing lsquoLoose Clusteredrsquo clones to the standard one Soluble solids were at 22-23deg Brix but acids were relatively high at 14-16 gl But all the loose-clustered clones had significantly less fruit rots than the standard Vignoles clone

The 10 day forecast is showing a few more days of warm weather (70-80deg days) with midweek rain and cooling tem-peratures by next weekend

Long Island (Alice Wise) Long Island is experiencing a stretch of unprecedented sun-ny dry weather It has been a vineyard managerrsquos dream harvest Wersquore due for a few showers on 926 but nothing major Only 19rdquo of rain was recorded in August with only 12rdquo thus far in September

The Cornell research vineyard has been struggling a bit with drought stress particularly young vines The Riverhead sandy loam soil along with weeds (under-vine mowing) has led to basal leaf discoloration (yellowing or reddening) fol-lowed by basal leaf abscission Consequently we have been irrigating Fortunately harvest is proceeding at a good clip in fact it is possible that we will begin with Chardonnay later next week

Bird pressure has been relatively low Populations have definitely declined in recent years We used to fight huge flocks of starlings and lots of robins Due to the dry weather cluster rot has been pretty minimal and thus fruit fly popu-lations are modest so far How nice is it to be able to say that

Only the usual suspects have some minor cluster rot Pinot Noir had a touch of sour rot and some berry dehydration Auxerrois usually the poster child for cluster rot had some Botrytissour rot but a lot of it was related to bee and wasp

Finger Lakes (Hans Walter-Peterson)The pace of harvest has picked up in the Finger Lakes over the past week Much of the Cayuga White in the area has been picked this week including at our Teaching Vineyard in Dresden We are also starting to see early picking of Chardonnay Pinot noir and a couple of other varieties that are destined for sparkling wine production Results from this weekrsquos sampling run show that most varieties still are relatively high in acidity with pH values generally around 300 and TA around 10 gl or higher so harvest for a number of these will likely wait for at least another week or more meaning October will be a busy month in the vineyards and at the crush pads in the Finger Lakes

We have been fortunate so far this harvest when it comes to water We have received about 50 of our monthly average rainfall for September this year which has meant less pressure for fruit rot diseases like botrytis and sour rot The biggest issue with dis-ease so far this season continues to be downy mildew which in some blocks is having a noticeable impact on the amount of functional leaf area and therefore fruit ripening as well In a few vineyards with substantial DM pressure we are seeing a reduction in brix ac-cumulation compared to healthier vineyards nearby Most vineyards have managed the disease well up to

Improving Management of Bindweed in Vineyards

Hans Walter-Peterson Finger Lakes Grape Program

Bryan Brown NYS IPM Program

Donald Caldwell Finger Lakes Grape Program

In recent years perennial weeds have become more and more of an issue in vineyards in the Finger Lakes region Weeds like Virginia creeper (Parthenocissus quinquefolia) poison ivy (Toxicodendron radicans) hedge bindweed (Calystegia sepium) and field bindweed (Convolvulus arvensis) can be found not only amidst the ground cover in vineyards but also climbing into the canopy where they compete for sunlight and can reduce air circulation and spray penetration which can have negative consequences on vine health and fruit quality

Because they are perennial weeds they can be much more difficult to control than annual weed species in part due to extensive rooting systems or rhizomes that can continue to regenerate new plants after those above ground have been removed by cultivation or herbicides The standard treatment for many perennial weeds has been multiple applications of a systemic herbicide such as glyphosate which can translocate into the below-ground portion of the plant and begin to weaken its ability to regenerate While effective there is increasing concern about glyphosate use in agriculture and elsewhere due to emerging resistance

to the material in certain weed species and concern in the public about possible health concerns with use of glyphosate

In 2018 we started a trial to look at a couple of alter-native control strategies for field bindweed compared to the standard glyphosate program In addition to applications of glyphosate (3 applications) we also looked at another herbicide Matrix (rimsulfuron 2 ap-plications) and cultivation (3 passes by hand) as our other treatments The trial was conducted at the Finger Lakes Teaching amp Demonstration Vineyard where we have had significant populations of bindweed since its establishment

Field bindweed is a problem for growers because it grows as a vine and climbs up grapevine trunks

Because of the dry condi-tions during the spring and summer of 2018 bindweed populations were relatively low com-pared to other years All three of the treatments controlled the bindweed better than the control (top graph in Figure 1) with the two chemical treatments performing slightly better than cul-tivation The two chemical treatments also controlled other weed species similarly overall while weed cover in the cultivation treatment increased dramatically starting in mid-August Two factors likely contributed to this increase 1) the arrival of more steady rains and 2) the end of our cultivation treatment at this point in the season However the cultivation treatment still had only about 50 ground cover under the trellis as opposed to the control treatment which was almost completely covered by the end of the season

We also measured the amount of biomass of bindweed and other weeds as dry weight in each treatment (Fig-ure 2) All three treatments had similar amounts of bindweed and other weed species at the end of the sea-son statistically speak-ing even though the cul-tivation treatment had higher non-bindweed biomass than the two chemical treatments

In 2019 we took another look at the treatments to measure the amount of bindweed that returned the following year The data was collected on June 5 and no herbicides or cultivation were ap-plied to the plots before-hand The data show that the bindweed emergence just prior to bloom in the following season was significantly reduced by all of the treatments but most significantly by the two chemical treatments (Table 1)

Table 1 Treatment effects on bindweed growth in early 2019 following 2018 treat-ments Data collected on June 5 2019

In 2019 the trial was moved to a commercial vineyard on Keuka Lake with a history of bindweed pressure In addition to the three treatments already discussed we added two additional treatments consisting of an-other herbicide dichlobenil (lsquoCasoronrsquo) and a ldquocombo platterrdquo treatment using cultivation glyphosate and Matrix one time each during the season for a total of six treatments We havenrsquot had a chance to crunch the numbers from this year yet but the results from both years of the trial along with some comparisons of the economics of different strategies will be presented at BEV NY this winter

This week we harvested fruit from the ldquoloose-clusteredrdquo Vignoles planting at the Cornell Lake Erie Research and Extension Laboratory Out of the eight selections plus the lsquoStandard Clonersquo we brought grapes from four selections and the stan-dard to Geneva to be vinified

Field evaluations showed that all of the selections had much lower levels of Botrytis and sour rot than the standard clone The four that we har-vested had little fruit rot (lt5 of cluster area vs 38 on the standard clone) - and only 10 of the clusters we harvested had ANY fruit rots (vs 90 of the standard clusters that had at least some rot)

Herersquos how the fruit looked (right)

Improving Management of Bindweed in Vineyards

Hans Walter-Peterson Finger Lakes Grape Program

Bryan Brown NYS IPM Program

Donald Caldwell Finger Lakes Grape Program

In recent years perennial weeds have become more and more of an issue in vineyards in the Finger Lakes region Weeds like Virginia creeper (Parthenocissus quinquefolia) poison ivy (Toxicodendron radicans) hedge bindweed (Calystegia sepium) and field bindweed (Convolvulus arvensis) can be found not only amidst the ground cover in vineyards but also climbing into the canopy where they compete for sunlight and can reduce air circulation and spray penetration which can have negative consequences on vine health and fruit quality

Because they are perennial weeds they can be much more difficult to control than annual weed species in part due to extensive rooting systems or rhizomes that can continue to regenerate new plants after those above ground have been removed by cultivation or herbicides The standard treatment for many perennial weeds has been multiple applications of a systemic herbicide such as glyphosate which can translocate into the below-ground portion of the plant and begin to weaken its ability to regenerate While effective there is increasing concern about glyphosate use in agriculture and elsewhere due to emerging resistance

to the material in certain weed species and concern in the public about possible health concerns with use of glyphosate

In 2018 we started a trial to look at a couple of alter-native control strategies for field bindweed compared to the standard glyphosate program In addition to applications of glyphosate (3 applications) we also looked at another herbicide Matrix (rimsulfuron 2 ap-plications) and cultivation (3 passes by hand) as our other treatments The trial was conducted at the Finger Lakes Teaching amp Demonstration Vineyard where we have had significant populations of bindweed since its establishment

Field bindweed is a problem for growers because it grows as a vine and climbs up grapevine trunks

Because of the dry condi-tions during the spring and summer of 2018 bindweed populations were relatively low com-pared to other years All three of the treatments controlled the bindweed better than the control (top graph in Figure 1) with the two chemical treatments performing slightly better than cul-tivation The two chemical treatments also controlled other weed species similarly overall while weed cover in the cultivation treatment increased dramatically starting in mid-August Two factors likely contributed to this increase 1) the arrival of more steady rains and 2) the end of our cultivation treatment at this point in the season However the cultivation treatment still had only about 50 ground cover under the trellis as opposed to the control treatment which was almost completely covered by the end of the season

We also measured the amount of biomass of bindweed and other weeds as dry weight in each treatment (Fig-ure 2) All three treatments had similar amounts of bindweed and other weed species at the end of the sea-son statistically speak-ing even though the cul-tivation treatment had higher non-bindweed biomass than the two chemical treatments

In 2019 we took another look at the treatments to measure the amount of bindweed that returned the following year The data was collected on June 5 and no herbicides or cultivation were ap-plied to the plots before-hand The data show that the bindweed emergence just prior to bloom in the following season was significantly reduced by all of the treatments but most significantly by the two chemical treatments (Table 1)

Table 1 Treatment effects on bindweed growth in early 2019 following 2018 treat-ments Data collected on June 5 2019

In 2019 the trial was moved to a commercial vineyard on Keuka Lake with a history of bindweed pressure In addition to the three treatments already discussed we added two additional treatments consisting of an-other herbicide dichlobenil (lsquoCasoronrsquo) and a ldquocombo platterrdquo treatment using cultivation glyphosate and Matrix one time each during the season for a total of six treatments We havenrsquot had a chance to crunch the numbers from this year yet but the results from both years of the trial along with some comparisons of the economics of different strategies will be presented at BEV NY this winter

This week we harvested fruit from the ldquoloose-clusteredrdquo Vignoles planting at the Cornell Lake Erie Research and Extension Laboratory Out of the eight selections plus the lsquoStandard Clonersquo we brought grapes from four selections and the stan-dard to Geneva to be vinified

Field evaluations showed that all of the selections had much lower levels of Botrytis and sour rot than the standard clone The four that we har-vested had little fruit rot (lt5 of cluster area vs 38 on the standard clone) - and only 10 of the clusters we harvested had ANY fruit rots (vs 90 of the standard clusters that had at least some rot)

Improving Management of Bindweed in Vineyards

Hans Walter-Peterson Finger Lakes Grape Program

Bryan Brown NYS IPM Program

Donald Caldwell Finger Lakes Grape Program

In recent years perennial weeds have become more and more of an issue in vineyards in the Finger Lakes region Weeds like Virginia creeper (Parthenocissus quinquefolia) poison ivy (Toxicodendron radicans) hedge bindweed (Calystegia sepium) and field bindweed (Convolvulus arvensis) can be found not only amidst the ground cover in vineyards but also climbing into the canopy where they compete for sunlight and can reduce air circulation and spray penetration which can have negative consequences on vine health and fruit quality

Because they are perennial weeds they can be much more difficult to control than annual weed species in part due to extensive rooting systems or rhizomes that can continue to regenerate new plants after those above ground have been removed by cultivation or herbicides The standard treatment for many perennial weeds has been multiple applications of a systemic herbicide such as glyphosate which can translocate into the below-ground portion of the plant and begin to weaken its ability to regenerate While effective there is increasing concern about glyphosate use in agriculture and elsewhere due to emerging resistance

to the material in certain weed species and concern in the public about possible health concerns with use of glyphosate

In 2018 we started a trial to look at a couple of alter-native control strategies for field bindweed compared to the standard glyphosate program In addition to applications of glyphosate (3 applications) we also looked at another herbicide Matrix (rimsulfuron 2 ap-plications) and cultivation (3 passes by hand) as our other treatments The trial was conducted at the Finger Lakes Teaching amp Demonstration Vineyard where we have had significant populations of bindweed since its establishment

Field bindweed is a problem for growers because it grows as a vine and climbs up grapevine trunks

Because of the dry condi-tions during the spring and summer of 2018 bindweed populations were relatively low com-pared to other years All three of the treatments controlled the bindweed better than the control (top graph in Figure 1) with the two chemical treatments performing slightly better than cul-tivation The two chemical treatments also controlled other weed species similarly overall while weed cover in the cultivation treatment increased dramatically starting in mid-August Two factors likely contributed to this increase 1) the arrival of more steady rains and 2) the end of our cultivation treatment at this point in the season However the cultivation treatment still had only about 50 ground cover under the trellis as opposed to the control treatment which was almost completely covered by the end of the season

We also measured the amount of biomass of bindweed and other weeds as dry weight in each treatment (Fig-ure 2) All three treatments had similar amounts of bindweed and other weed species at the end of the sea-son statistically speak-ing even though the cul-tivation treatment had higher non-bindweed biomass than the two chemical treatments

In 2019 we took another look at the treatments to measure the amount of bindweed that returned the following year The data was collected on June 5 and no herbicides or cultivation were ap-plied to the plots before-hand The data show that the bindweed emergence just prior to bloom in the following season was significantly reduced by all of the treatments but most significantly by the two chemical treatments (Table 1)

Table 1 Treatment effects on bindweed growth in early 2019 following 2018 treat-ments Data collected on June 5 2019

In 2019 the trial was moved to a commercial vineyard on Keuka Lake with a history of bindweed pressure In addition to the three treatments already discussed we added two additional treatments consisting of an-other herbicide dichlobenil (lsquoCasoronrsquo) and a ldquocombo platterrdquo treatment using cultivation glyphosate and Matrix one time each during the season for a total of six treatments We havenrsquot had a chance to crunch the numbers from this year yet but the results from both years of the trial along with some comparisons of the economics of different strategies will be presented at BEV NY this winter

ldquoLoose-Clusteredrdquo VignolesTim Martinson

This week we harvested fruit from the ldquoloose-clusteredrdquo Vignoles planting at the Cornell Lake Erie Research and Extension Laboratory Out of the eight selections plus the lsquoStandard Clonersquo we brought grapes from four selections and the stan-dard to Geneva to be vinified

Field evaluations showed that all of the selections had much lower levels of Botrytis and sour rot than the standard clone The four that we har-vested had little fruit rot (lt5 of cluster area vs 38 on the standard clone) - and only 10 of the clusters we harvested had ANY fruit rots (vs 90 of the standard clusters that had at least some rot)

Herersquos how the fruit looked (right)

ldquoLoose-Clusteredrdquo VignolesTim Martinson

This week we harvested fruit from the ldquoloose-clusteredrdquo Vignoles planting at the Cornell Lake Erie Research and Extension Laboratory Out of the eight selections plus the lsquoStandard Clonersquo we brought grapes from four selections and the stan-dard to Geneva to be vinified

Field evaluations showed that all of the selections had much lower levels of Botrytis and sour rot than the standard clone The four that we har-vested had little fruit rot (lt5 of cluster area vs 38 on the standard clone) - and only 10 of the clusters we harvested had ANY fruit rots (vs 90 of the standard clusters that had at least some rot)

Herersquos how the fruit looked (right)

ldquoLoose-Clusteredrdquo VignolesTim Martinson

This week we harvested fruit from the ldquoloose-clusteredrdquo Vignoles planting at the Cornell Lake Erie Research and Extension Laboratory Out of the eight selections plus the lsquoStandard Clonersquo we brought grapes from four selections and the stan-dard to Geneva to be vinified

Field evaluations showed that all of the selections had much lower levels of Botrytis and sour rot than the standard clone The four that we har-vested had little fruit rot (lt5 of cluster area vs 38 on the standard clone) - and only 10 of the clusters we harvested had ANY fruit rots (vs 90 of the standard clusters that had at least some rot)

Herersquos how the fruit looked (right)
