This week I have been seeing a lot of Southern Blight (Sclerotium rolfsii) in fields. Most fields were caught up on their irrigation – providing wet soils, a little more humidity, and warm soil temperatures ideal for Southern Blight. The fungus’ white mycelium is stringy looking (top photo) compared to the puffy looking mycelium of Sclerotinia Blight. Southern Blight has round sclerotia that appear as white or brown tiny balls (bottom photo) compared to the black, flaky looking sclerotia of Sclerotinia Blight. The fungus survives growing on dead plant material. It survives year to year growing on the soil surface but cannot survive more than a year if it is buried deeply. Usually crop rotations of 2 to 4 years are required to significantly reduce it. There are numerous products available to control Southern Blight.
