Contans

New Fungicide for White Mold - Contans ® –  Soil-active : works in the soil or on crop

residue attacking Sclerotinia, the source of the disease, before it infects plants

–  Exempt from EPA requirements for food tolerance means no plant back or rotational crop issues

–  Zero hour re-entry interval –  Huge interest this year - White Mold

can reduce yield by more than 50%

Contans® -Controlling White Mold in Dry Beans and Soybeans

•  Contans attacks Sclerotinia at the source •  C. minitans attacks and destroys the sclerotia & mycelia

of –  Sclerotinia sclerotiorum –  Sclerotinia minor

•  Commercial focus on soybeans, dry beans, snap beans, other legume crops, leafy vegetables, canola and sunflowers

What is Contans®WG ?

•  Contans®WG consists of the natural soil fungus

Coniothyrium minitans.

•  Coniothyrium minitans is a specific antagonist of the resting survival structures (sclerotia) of the plant pathogens Sclerotinia sclerotiorum, Sclerotinia trifoliorum, Sclerotinia minor and Sclerotium cepivorum.

•  1 kg Contans®WG contains 1 x 1012 active spores of the soil fungus Coniothyrium minitans

How does Contans® WG work?

Coniothyrium minitans attacks the survival structures (sclerotia) of Sclerotinia spp.

• Once applied and incorporated into the soil, the spores of Coniothyrium minitans germinate in the moist soil.

•  The mycelium of Coniothyrium minitans attacks and destroys the resting survival structures (sclerotia) of the plant pathogen in the soil within two to three months.

Efficacy of Contans®WG toward the sclerotia of Sclerotinia sclerotiorum in the soil

2009 White Mold Outbreak

• Damp weather and cool temperatures have caused a major outbreak of white mold on soybeans in OH for the 1st time in almost a decade according to researchers. • ND, MN, IA, WI, IL, IN, OH, and MI have reported incidence of the disease due to the cool, wet summer.

• Red area of the map RRV and thumb of MI -edible beans, sunflowers, and canola

high levels of incidence • Green area of the map is where a

higher incidence of the disease is found on soybeans

• Blue area of the map -processing beans with a high level of incidence.

White Mold Management Strategies •  Dr. Carl Bradley provided several management strategies which include

cultural practices, as well as chemical and biological products. •  It is important to note that Contans WG should not be applied to flowering

soybean plants. Rather, it should be applied to the soil in the fall after harvest or in the spring prior to planting

--Carl A. Bradley •  Another consideration is to use Contans after soybean harvest. Contans is

a biological control agent proven to be effective in white mold control in many crops.

---Iowa State – IPM Newsletter 8-15-09

•  Contans applied 1lb per acre in Fall. •  Followed by 1 lb per acre early spring . •  Treat soil not the plant to reduce fungal Pathogen

2006 Wisconsin Soybean field. Contans spring applied 1 lb/acre. No-till field. Red arrow shows area where grower ran out of product. Darker shading indicates higher incidence of white mold. See aerial yield map on next slide.

Control of Sclerotia of Sclerotinia sclerotiorum on Snap beans with Contans®WG

New York State Agricultural Experiment Station, Cornell

H. Dillard & A. Cobb

Crop: Beans

Plot size: 6 foot sqaure

Replications: 4, randomised

Date of artificial infection: June 13

Number of applied sclerotia: 7962 per plot (per 340 litres of soil)

Rate of application: 4 lb Contans WG / acre

Date of application: June 13

Application: Backpacksprayer, 2 x 50 gal/A

Date of planting: June 13

Evaluation: October 13. Recovering of 5 x 100 ml samples of soil from each rep/treatment. Counting of sclerotia. Fisher´s Protected LSD (P<0,05)

IPM of White Mold on Snap Beans Stevenson et al., University of Wisconsin-Madison, USA

Rate of application: 1.8 & 3.6 lb Contans WG per acre

Date of application: Just before panting (6-10 weeks before bloom)

Application: Spraying, soil incorporation

Date of planting: Plover: June 2001, Hancock: April

Fungizides used: Hancock: Topsin M 70 WP (2.0), Plover: Benalte (1.5)

Evaluation: White mold development immediately before commercial harvest. Four 5-feet-long sections of row (randomized). Fisher´s Protected LSD (P<0,10)

Contans®WG – The Advantages •  Environmentally compatible and plant-carefully biological fungicide

•  Reduces and eliminates the disease causing sclerotia from treated soil

•  Cost effective

•  Prevents root-infection caused by soil growing mycelium of the pathogen

•  Prevents a new contamination of the soil with sclerotia

•  Contans® WG attacks and destroys the surviving structures (sclerotia) of the disease

•  Contans® WG reduces the source of Sclerotinia-diseases and provides long term protection

• Spores do not infect green tissue

• Begin growth on dead tissue – flower parts preferred

• Oxalic Acid Produced  Tissues Die
