Location: Sclerotinia stem rot occurs throughout the state, but has been more severe in fields surrounded by woods, with high plant populations, and high fertility soils.

Time of infection: Wet weather before and during flowering of the soybean plant is important for infection. The duration of the wet period during flowering and the capacity of the soybean canopy to keep stems wet for extended periods of time contribute to disease severity. Symptoms first appear in late August or early September.

Management: · Resistant varieties · Seed treatment · No-till
