Abstract:
An experiment was conducted during kharif, 2018 to study the persistence and dissipation of mancozeb residues during fruit formation stage of chilli hybrid (strong 386). Application of mancozeb 75% WP (Dithane M 45) was imposed as foliar spray thrice at 7 days interval at recommended and double the recommended dose of 1500 g ai/ha and 3000 g ai/ha. Initial residue deposits of mancozeb (as CS2) observed in green chilli was 0.36 and 1.24 mg/kg which dissipated to less than limit of quantitation of 0.05 mg/kg by 15th day in both the doses respectively. The half life of mancozeb residue was found to be 1.32 and 2.07 days in recommended and double the recommended doses respectively. The residues of mancozeb (based on CS2) in red chilli and soil collected at harvest were found to be below limit of quantification (LOQ) in both the doses respectively.
