 If you're worried about sclerotinia white mold in soybeans, our number one recommendation is Cobra at 6 ounces, sprayed right before flowering or just as flowering begins. While Cobra isn't the very best product for control, it offers the greatest value since it only costs $4. Endura is an SDHI product, which is the best on white mold, and it's labeled in most crops. The problem is it costs over $40 per acre.
