Soybean growers have a new fungicide option to manage white mold.

State regulatory officials in Illinois, Indiana, Iowa, Michigan, Minnesota, Nebraska, North Dakota, Ohio, South Dakota and Wisconsin have approved a Section 2(ee) recommendation for ProlineĀ® fungicide from Bayer CropScience to suppress Sclerotinia stem rot of soybeans.

Studies have shown that Proline effectively suppresses Sclerotinia stem rot, commonly called white mold, in soybeans while promoting healthy crop development. White mold is a common disease that can cause major yield reductions if left untreated. Yield losses usually occur when disease threshold hits 15 percent and can range from 1.3 to 3.7 bu/A for every 10 percent increase in disease incidence.

White mold, which also can reduce seed quality and can cause seed contamination, typically appears after canopy formation. Bayer CropScience recommends an initial application of Proline before canopy closure at early flowering for increased effectiveness against white mold.

Proline fungicide also provides powerful protection against various diseases in other crops, including canola, chickpeas, peanuts, lentils and dry beans, while preserving crop quality and contributing to enhanced yield and profit.
