Symptoms of White Mold

Infected plants appear wilted, which might be mistaken for drought. As the fungus invades the stem, all the plant tissue up from the infection point dies. This causes leaves and stems to turn brown and stand erect above the soybean canopy

A closer inspection of the stems may reveal lesions and a covering of thick white mold, which is diagnostic for white mold (below).

Another diagnostic sign of white mold infection are the hard, dark structures called sclerotia that form on the inside and outside of the stem (below).
