p-Chlorophenyl p-Chlorobenzenesulfonate 
53° -labeled p-chlorophenyl p-chlorobenzenesulfonate was hardly 
decomposed in eggs and adults of the citrus red mite. When injected 
into the abdomen of the American cockroach, decomposition of this acaricide 
gave rise to p-chlorobenzenesulfonic acid. In citrus sapling and soybean 
seedling, p-chlorophenyl p-chlorobenzenesulfonate penetrated into the 
plant and was decomposed to p-chlorobenzenesulfonic acid and other 
compounds (Tomizawa, 1960a).

Ciodrin (a-Methylbenzyl-3-hydroxycrotonate dimethyl phosphate) 
A study of the absorption, elimination, and metabolism of orally 
administered p22 labeled ciodrin in a lactating ewe indicated moderate 
absorption and rapid elimination. Dimethyl phosphoric acid accounted 
for 61-90% of the radioactivity in the urine. Several other metabolites 
were noted but not identified. Similar results were obtained when the 
experiment was repeated with a lactating goat (Chamberlain, 1964a, b).
