Abstract
Spray residues of Guthion® (O,O-dimethyl S-(4-oxo-3H-l,2,3- bellzotriazine-3-methyl) phosphorodithioate), malathion, and methyl parathion on cotton plants were weathered by several natural or simulated climatological conditions and bioassayed with the boll weevil, Anthonomus grandis Boh. All the experiments were conducted in the lahoratory. Exposure to temperatures ahove 1000 F. for 4 to 6 hours during a 24-hour period had little or no effect on the residual toxicities of Guthion, malathion, or methyl parathion to the boll weevil. However, toxic residues of malathion and methyl parathion were affected adversely by exposure to high uatural light intensities of the magnitude of 13,000 foot-candles at elevated temperatUres. Residues of Guthion were affected adversely by simulated rain, but were not affected by high temperatures. Some data arc presented indicating that organophosphorus and chlorinated hydrocarbon insecticides can he combined to increase the toxicity of the residues to the boll weevil.
