Large isolated cotton leaves were treated with labeled temik. 
Temik disappeared rapidly. Temik sulfoxide appeared as the major 
metabolite with a small amount metabolized to the sulfone. By way of 
hydrolysis, Temik oxime was the primary hydrolytic product. The hydrolysis 
product of Temik sulfone or Temik oxime sulfone was also present C991); 
Under laboratory conditions, temik was degraded more slowly in soil 
than in cotton but similar metabolites were observed in both. In cotton, 
temik sulfoxide and sulfone, the nitrile sulfoxide and sulfone and oxime 
sulfoxide were observed. In soils studied, temik sulfoxide and sulfone, 
nitrile sulfoxide, oxime sulfoxide, and the oxime were observed. In both 
test systems, approximately five additional products were unidentified (305). 
Field studies confirmed the laboratory studies. In soil, however, much temik 
was lost by volatilization and/or leaching (1743).
