White mold caused by Sclerotinia sclerotiorum, continues to be a threat to soybean production. We have demonstrated that commercial biological control products Contans and Actinovate are effective in reducing the sclerotial population of Sclerotinia sclerotiorum in soil over multiple years and at multiple locations. Additionally the herbicide Cobra helps to eliminate the later stage infection. We are proposing to continue using this biocontrol agent herbicide combination to best suppress the disease in the field. In the greenhouse, we will examine the effect of fertilizers, herbicides, and fungicides on the survival and efficacy of biological controls for S. sclerotiorum control. Optimal...
