Interactions of Pyrethroid Insecticides and Toxaphene in Cotton


Journal Article

Effects of toxaphene on pyrethroid insecticide residues on cotton foliage were determined by spraying aqueous emulsions, extracting leaves with methylene chloride, separating the pyrethroid from toxaphene by preparative thin-layer chromatography, and quantitating by gas chromatography. Fenvalerate residues were increased up to 2-fold due to enhanced persistence in the presence of toxaphene. Permethrin residues were reduced by toxaphene, the effect being greater in 1RS, trans isomers after several applications. Toxaphene synergized fenvalerate and permethrin 2-fold in Spodoptera frugiperda; susceptibility of Heliothis virescens was increased 1.5-fold to both pyrethroids. © 1982, American Chemical Society.
