Title: PERSISTENCE AND DISSIPATION OF DIMETHOATE AND DICOFOL RESIDUES IN/ON PAPAYA
Abstract: Dicofol and dimethoate are used for control of papaya mite and aphids respectively. An experiment was conducted to study their persistence an pattern on papaya following spray applications at the recommended dose of 0.05% and double the recommended dose of 0.1 %. Initial residues of dimethoate was 2.96 and 4.23 ppm and the residues persisted for 25 days. The residues dissipated at the half life of 3.7 and 5.04 days and suggested pre harvest interval (PI-II) were three and five days, In papaya pulp the level of dimethoate residues was very long wliich was maximum of 0.17 and 0.32 ppm on the 3rd day. Initial residues 0f3. 14 aird 5.97 ppm of dicolol were recovered following spray applications at the recommended dose 0f 0.05% and double the recommended dose of 0.10%. The residues persisted for 15 days. The residues dissipated at the half-life of 2.2 d 2 an 9 days and the pre harvest interval (PHI) worked out was one and two days, respectively.
