Butonate (Tribuphon) [0,0-Dimethyl-1-butryloxy-2,2,2-trichloroethylphosphate ] 
In the liver and blood of warm blooded animals, butonate was degraded 
primarily by hydrolysis of P-C bond with formation of dimethylphosphate. 
Small amounts of the desmethylbutonate also formed in the blood in vitro 
(1562, 1730). Butonate was also hydrolyzed by fish (1681). 
In insects, the organic acid was removed by esterase action and 
trichlorofon (dipterex) was formed, which in turn was metabolized to DDVP 
(1562). 
After exposure of plants to butonate, trichlorofon was observed. Twenty- 
four hours after application, the trichlorofon amounted to 55-65% of the 
applied dose on apples, 504, on plums; 17-25%, on cherries; 54, on peas; 
65% on immature wheat; and 18%, on mature wheat. The half-life on apples 
and plums was 1,5 days; on cherries, 0.5 days (1562).
