Abstract:Field experiments were conducted in 1965 and 1966 to determine the effectiveness of aerial applications of undiluted malathion LV concentrate (a 95% technical formulation) for control of the alfalfa weevil, Hypera postica (Gyllenhal) , in Ohio. Single applications of 16 fluid oz per acre, made with Mini-Spin nozzles when air temperatures were 70˚F or higher, provided control for 14 days. When the temperature was much below 65-70˚F, control was obtained for 7 days. Applications of 16 and 11 fluid oz per acre, made under similar conditions but using flat-spray nozzles, provided control for 12 and 7 days, respectively.
