Abstract:

Persistence behavior of imidacloprid and beta-cyfluthrin in black pepper was studied following application of formulation of Solomon at 0.6 (recommended dose) and 1.2 (double recommended dose) g a. i. ha-1 for one pepper production cycle. The results also showed that the Solomon at 0.6ml/L concentration significantly suppressed the pest infestation in pepper vines. Pepper vine treated with Solomon produce more berries compared to control and showed no phytotoxicity. Analytical procedure of Solomon active ingredient was validated prior to actual analysis. Satisfactory recoveries ranging between 87.6%- 106.7% were obtained for the fortified pepper berries samples. Results showed low level of imidacloprid and beta-cyfluthrin residues in dried pepper berries ranging between �?�0.01mg/kg to 1.43mg/kg and �?�0.01mg/kg to 1.612mg/kg respectively. The half-life value period for imidacloprid were found to be 2.06 and 2.30 days and for beta-cyfluthrin, these values were observed to be 1.57 and 1.49 days respectively at recommended and double recommended dose. Imidacloprid and beta-cyfluthrin residue dissipated below the limit of quantification (LOQ) of 0.01mg kg-1 after 7 and 9 days respectively at recommended and double recommended dose. Soil sample collected 15 days after the last spray did not show the presence of Imidacloprid and beta-cyfluthrin residue at their detection limit of 0.01 mg/kg.
