Story in Brief

Considering manufacturers no longer produce the commonly used, topically applied herbicide Alanap (naptalam), watermelon producers could benefit from an additional topically applied herbicide that provides residual control for select grasses and pigweeds. The UGA Cooperative Extension agent in Crisp County collaborated with the UGA weed scientist to establish a trial in Crisp County to evaluate effects of in-row, topical applications of Dual Magnum (S-metolachlor) in watermelons. Findings from this project showed S-metolachlor applied overtop to be harmful to watermelon seedlings and should not be considered as an herbicide option for watermelon producers. Findings from this project will be made available to watermelon producers during annual county watermelon production meetings as well as Georgia Watermelon Association Annual meetings.
