Evaluating organophosphate alternatives for rootworm management in peanut

Field studies were conducted from 2017 to 2020 to evaluate the efficacy of select insecticide active ingredients and application methods against rootworm species (Diabrotica undecimpunctata and D. balteata) in peanut. The experiments were conducted at the Southwest Georgia Research and Education Center in Plains, GA. Pod damage evaluations were conducted at approximately 25 or 36 days after treatment and again at harvest. Results suggest that peanut in Georgia can compensate for early season pod injury caused by rootworm species and indicate that insecticides applied as chemigation treatments may significantly reduce pod injury.
