    Virginia Peanuts: Conditions Ideal for Sclerotinia Blight Development

    By Chris Drake, Virgina Cooperative Extension

    Now, let’s touch on peanuts for a bit. I have scouted several fields in the area and found sclerotinia blight in some fields. It has not been a heavy infestation thus far, but the disease is present.

    sclerotinia_blight_peanuts_virginia_chris_drakeThe weather of late has been ideal for the development of this devastating disease. Please scout your fields regularly to determine if treatment is necessary. The picture shown is a textbook example of sclerotinia blight symptoms. I found this just this morning in a field of Sugg in Newsoms. Even though Bailey and Sugg possess resistance to this disease, we can still see outbreaks in a high pressure scenario, so do not rest easy while optimal disease conditions exist.


    Omega 500F is the best treatment at 1 pt. per acre, but Fontelis at 1 pt/ acre applied in sequential applications provides some level of suppression of the disease according to Dupont. This has not been proven in trial work at TAREC, but farmer reactions to applications in 2012 were favorable.

    As always, rely on the peanut cotton infonet (1-800-795-0700) or access online for leafspot and sclerotinia advisories.
