Abstract
Ultra-law-volume (ULV) insecticide sprays to control cotton insects are being increasingly used each year. Previous work on the residual nature of insecticides applied as ULV and water emulsion sprays (Nemec and Adkisson 1966, Nemec et. at 1968) have shown that ULV applications deposited more insecticide than water emulsion sprays on the crops and that the residual toxicity of the insecticide was longer. Therefore, increased use of ULV sprays for controlling cotton insects could possibly result in a greater potential health hazard to persons working in fields so treated. The study reported here was initiated to determine the amounts of insecticide adsorbed on the arms and hands of 2 persons after they entered fields which had been treated with ULV sprays of methyl parathion.Keywords
