I have noticed and received some reports of Sclerotina Stem Rot or White Mold in the soybeans.  The infection generally occurs at flowering and symptoms usually take 2 to 4 weeks to appear.  Cool wet conditions and a dense canopy favors the infection of the disease.   The first sign of White Mold is scattered wilted/dead plants in the field.   Closer examination shows White Mold on the exterior of the lower stem.   If you have White Mold present here are a few things to keep in mind.   Different varieties differ in their susceptibility so check with your seed advisor on your varieties rating to White Mold.  According to Ohio State It takes at least a 20% incidence to begin to measure yield loss.  Not all fields have the Scerotinia inoculum and it must be present from a previous crop to have White Mold develop.  Once inoculum is present in a field it will be there forever.  If you do have white mold in a field harvest those fields last so you will not introduce the fungus into more fields.  The White Mold fungus that are left on the surface will degrade quicker in No-till than the fields that are worked.    If you would like more information and would like your fields scouted for White Mold contact your Local Mercer Landmark Representative.
