Abstract
Residue persistence of beta cyfluthrin and imidacloprid on mango was carried out after giving spray application of the combination formulation, beta cyfluthrin 9%+imidacloprid 21% (Solomon 300 OD) 3 times at the fruit formation stage. The treatments were, untreated control, standard dose of 75g a.i. ha(-1) and double dose of 150g a.i. ha(-1). Initial residues of beta cyfluthrin on mango fruits were 0.04 and 0.12mgkg(-1) from treatments at the standard and double doses, respectively. The residues dissipated with the half-life of 2.4 and 2.6days and persisted for 5days only. Initial residues of imidacloprid on mango fruits were 0.14 and 0.18mgkg(-1) from treatments at the standard and double doses, respectively. Imidacloprid residues degraded with the half-life of 3.06 and 4.16days, respectively and persisted for 10days. Mature mango fruits at harvest were free from residues of both insecticides. A safe pre-harvest interval of 8days is recommended for consumption of mango fruits after treatment of the combination formulation.
