Abstract
Field trials were conducted at two locations viz., Hyderabad and Palem to study the dissipation kinetics of monocrotophos in castor plant, its bi-products and soil. Monocrotophos 35 % EC at two test doses @ 437 mL/ha and 874 mL/ha was applied to castor crop at flowering stage followed by capsule formation stage. The leaf samples drawn periodically were analyzed by liquid chromatography and tandem mass detection (LC-MS/MS). The initial residues of recommended dose of monocrotophos in castor leaves were found to be 4.641 and 6.22 mg/kg at Hyderabad and Palem, respectively. More than 98 % of monocrotophos residues had dissipated after 10 days in both the test doses. Castor seeds, castor oil and castor cake and soil samples collected at harvest which happened to be 60 days after the last application did not show the presence of residues of monocrotophos at their determination limit of 0.05 mg/kg. These results would be helpful in setting maximum residual limit (MRL) of monocrotophos in castor in India.
