Durham, North Carolina (September 24, 2009)--Mild damp weather throughout the Midwest has created optimal conditions for the widespread development of white mold in soybeans and edible beans. Outbreaks have been reported in most of the soybean and edible bean production states in 2009. Early management of white mold is key to protecting yields in soybeans and edible beans. When white mold hits late in the season the impact can be most severe with varying yield losses of up to 50 percent.


University testing has shown fall applications of Contans® are highly effective at reducing the population of sclerotinia, the pathogen that causes white mold in these key legume crops. According to Dr. Carl A. Bradley, University of Illinois, Contans WG should be applied to the soil in the fall after harvest or in the spring prior to planting. Fall or spring applications of Contans reduce the amount of sclerotia available to infect the susceptible crop in the coming years.

Data generated by researchers within the International Sclerotinia Workshop show sclerotia which cause white mold survive in the soil for 5 years or more making long term population reduction a useful grower strategy. SipcamAdvan Product Manager, Scott Peterson explains, “Similar to how annual applications of herbicides reduce the weed seed bed, Contans goes after the source of the disease, reducing the fungus population year after year.”

Contans Biofungicide is available from SipcamAdvan as part of their expanding portfolio to meet the needs of US growers. “Offering differentiated solutions to top distributors is a key goal of SipcamAdvan,” said Vice President of Marketing Adam Burnhams. “We have an exciting pipeline of both conventional and biorational solutions in development and look forward to our continued partnership with distribution.”

SipcamAdvan is owned by the Sipcam-Oxon Group, an Italian company recognized worldwide for its formulation and manufacturing expertise. SipcamAdvan uses a distribution-focused marketing strategy to provide traditional chemical and biorational products to the agriculture, turf and ornamental, home and garden, and pest management markets in the U.S. and Mexico.
