Persistent toxicity of some readymix products against Earias vittella (Fab.)
Author(s): RB Mankar, US Kulkarni and SS Madankar
Abstract: The persistent toxicity of some readymix insecticides against Earias vittella (Fab.) on okra were conducted during 2016-17. The persistent toxicity studies revealed that, Indoxacarb 14.5% SC + Acetamiprid 7.7% SC recorded the highest Persistent Toxicity index (PTi) while Pyriproxifen 5% EC + Fenpropathrin 15% EC recorded the lowest PTi. Computation of PT50 values to determine time duration for 50% kill on residual toxicity revealed that Indoxacarb 14.5% SC + Acetamiprid 7.7% SC recorded highest residual toxicity while Pyriproxifen 5% EC + Fenpropathrin 15% EC recorded lowest the residual toxicity. Based on PTi and PT50 values readymix insecticide formulations can be arranged in descending order for their relative persistence as Indoxacarb 14.5% SC + Acetamiprid 7.7% SC > Profenophos 40% EC + Cypermethrin 4% EC > Novaluron 5.25% SC + Indoxacarb 4.5% SC > Pyriproxifen 5% EC + Fenpropathrin 15% EC.
