Residual Toxicity of Newer Insecticide Molecules against Shoot and Fruit Borer of Okra

Abstract

Seven new molecule insecticides viz., Deltamethrin, Lambda-cyhalothrin, Emamectin benzoate, Indoxacarb, Bifenthrin, Rynaxypr and Flubendiamide were bio-assayed against okra shoot and fruit borer (Earias vittella) to study the residual toxicity on Okra at College of Agriculture, Raipur during the Rabi applied season(2014-15 and 2015-16).. On the basis of average LT50 values, the order of toxicity was Emamectin Benzoate > Indoxacarb > Lambda-Cyhalothrin > Rynaxypr > Flubendiamide > Deltamethrin > Bifenthrin against okra shoot and fruit borer.

Determination of thiamethoxam residues and dissipation kinetic in tomato plants and its efficacy against Bemisia tabaci under open field eco system

“…On okra, Pawar et al (2016) reported that thiamethoxam was effective in aphids, jassids, and whiteflies control. Pandey (2018) found that thiamethoxam 25 WG @ 0.006% was effective against aphids, leaf hoppers, and white fly on okra plants. Also, Karthik et al (2020) found that thiamethoxam 25% WG at 25 g a.i.…”

“…The sucking insect, Bemisia tabaci was controlled effectively on vegetables using neonicotinoids (Li et al, 2021). Also, Pandey (2018) found that thiamethoxam 25 WG was effective against aphids, leaf hopper and, whitefly. Maurya et al (2015) found that Thiamethoxam 70% WS as tomato seed treatment protected tomato from aphid and thrips with significant increase in the fruit yield.…”
