Abate (0,0,0',0'-tetramethyl 0,0'-thiodi-p-phenylene phosphorothioate) 
Studies with tritium-labeled Abate indicated that this insecticide was 
relatively resistant to metabolic degradation. Residues on bean leaves 
(Sieva lima bean) consisted primarily of intact Abate~about 70% of the applied 
dose. The major metabolite was the sulfoxide derivative-less than 5% of the 
dose. Traces of the sulfone derivative and the oxygen analog and glucosidic 
conjugates of the phenolic hydrolysis products from Abate and its sulfoxide 
and sulfone derivatives were also observed (127, 1553).
