Metabolic fate of dichloromethyl-O,O-diphenyl phosphonate (I) and dichloromethyl-O,O-Di-(p-nitrophenyl) phosphonate (II) in/on rice plants.
Metabolic fate of two dichloromethyl diaryl phosphonates (32P labelled) in/on rice plants was investigated. The test compounds were found to be less persistent on the surface of rice leaves with half lives 7.4 and 6.7 days respectively. Main degradation product from both the phosphonates were dichloromethyl phosphonic acid with trace of dichloromethyl-O-aryl phosphonate as a transitory intermediate product.
