Abstract:Field tests were conducted to compare some experimental sprayers for control of corn earworm, Heliothis zea (Boddie), in sweet corn. A ULV sprayer with 4 auxiliary air velocities. a ULV sprayer equipped to pick up and recirculate most spray particles that did not impinge on plant foliage, a commercial ULV nozzle at 2 atomizing pressures, and an injection sprayer that injects nonmiscible insecticides into the system were compared. All plots treated with insecticides had significantly better insect control than the untreated plots. The plots sprayed with the injection sprayer had significantly better insect control than plots sprayed with the ULV sprayer with the lowest auxiliary air velocity (8 km/h) and the commercial nozzle at both atomizing air pressures (1.4 and 0.7 kg/cm2). There were no significant differences between other treatments.
