A few developmental studies like hydrolysis, phytotoxicity and photolysis on O, O-bis(2, 4, 5-trichlorophenyl)methylphosphonate, a potential fungicide, were carried out. The compound had a half life of 15 and 3hr respectively at pH 8 and 10, and did not show any phytotoxicity on the germination of paddy, brinjal and cauliflower seeds as well as on young paddy seedlings. A possible photochemical transformation based on the isolation of methylphosphonic acid is also proposed.
