Hessian Fly Control in Wheat by Suppression of Fall Generations with Carbofuran1

Seed and soil treatments of the systemic insecticide, carbofuran, were investigated to determine their feasibility for control of the fall generation of the Hessian fly (Mayetiola destructor Say) on wheat (Triticum aestivum L.): By controlling the fall fly population levels, the second generation would not be of economic importance, and seed treatment would be an effective control method. The experiment was conducted in the field at Plains, Ga. on a sandy loam soil (Rhodic Paleudults; clayey, kaolinitic, thermic) and at Griffin, Ga. on a Cecil sandy loam soil (Typic Hapludults; clayey, kaolinitic, thermic). The cultivar ‘Holley’ was subjected to three carbofuran treatments; a seed treatment of 4.15 g AI/kg of seed, a broadcast soil treatment of 4.5 kg AI/ha, and an untreated control. The Hessian fly was effectively controlled in wheat by suppression of the first fall generation by using carbofuran either as a seed treatment or as a broadcast spray treatment. Seed treatments were biologically active for the period during which the first fly generation developed (ca. 30 days), while soil treatments remained biologically active for several months.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
