 If you're worried about sclerotinia, white mold, and soybeans, our number one recommendation is Cobra at six 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 four bucks. 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.
