Which Will It Be?Sclerotinia blight or Southern stem rot — depending on the weather, one of these is likely in Virginia fields.

摘要

Virginia producers find primarily three diseases in their peanut fields, says David Langston, plant pathologist at Virginia Tech's Tidewater Agricultural Research and Extension Center. "Most fungicide sprays are targeted to leaf spot, Sclerotinia blight or Southern stem rot."However, based on weather conditions during the season, producers are likely to only encounter leaf spot and one of the other two. If weather is favorable for Sclerotinia blight, then it is not the hotter sometimes dryer weather preferred by Southern stem rot.
