Bronze wilt of cotton (also referred to as Sudden Wilt and coppertop) has been reported in U.S. cotton during recent cropping seasons. The reports of this anomaly have come from south and central Texas, Louisiana, Missouri, and Georgia although scattered reports from the Mississippi Delta region have also occurred. The fields with reports of Bronze wilt were typically from clay or “heavy” soils in Texas and Louisiana, however, bronze wilt has also occurred on sandy soils in the Southeast U.S. and the north MS Delta. The occurrences of bronze wilt in fields appears to be closely related to severe stress periods of heat and/or drought, sometimes followed by periods of rain or over-irrigation.
