white mold of watermelon

White mold-While this disease has a huge host range, I have not known it to be an important problem on watermelon in Indiana. Below it is shown only in a transplant tray. However, I have observed vine death in the field due to white mold. Diagnostic is the irregular, dark sclerotia as in other crops.
