Abstract
Persistence and residue study of flubendiamide and deltamethrin on chickpea pods and soil was carried out following foliar application of flubendiamide 90 + deltamethrin 60: 150 SC (W/V) @ 22.5 g a.i. ha-1 and @ 15.0 g a.i. ha-1. In foliar application the initial residue of flubendiamide was found to be 0.61 and 1.35 mg kg-1 and deltamethrin to be 1.01 and 2.00 mg kg-1 at recommended and double the recommended dose, respectively. The residue dissipated below the limit of quantification at 7 and 10 for flubendiamide, 10 and 15 days for deltamethrin at recommended and double the recommended dose, respectively. The residue was below 0.05 mg kg-1 in chickpea pods and soil samples collected after 20 days of last application. Study of risk assessment revealed that the dose sprayed is completely safe, and waiting period of one day is to be observed.
