The Effect of Adjuvant Class on Absorption of Selected Cotton Harvest-Aids, and Resulting Necrosis

David Stair, Tom Cothren and Lee Tarpley


Cotton (Gossypium hirsutum) desiccation/defoliation is required for early harvesting by machine where the natural temperatures do not promote leaf drop. The harvest-aid compounds used to induce leaf drop are not consistently efficacious. Foliar absorption and the leaf area coverage of particular harvest-aid chemicals can greatly affect their efficacy. Tank mix partners and time of application can affect both absorption and coverage.
