The okra fruit borer (Earias vittella) and sucking pests are a key limiting factor in cultivation due to their severe crop destruction behaviour. An experiment was conducted during 2019–20 assess the bioefficacy of various new insecticides persistence chlorantraniliprole 18.50 sc residues fruits at research farm ICAR- Indian Institute Vegetable Research, Varanasi, Uttar Pradesh. Among treatments, tested 30 g a.i./ha reported be effective reducing damage by E. vittella (96%), as well infestation (87.81–1100%) with significantly higher marketable yield (8.88 t/ha) recorded under open field situations. Ethyl acetate used extract contaminants from matrix, PSA magnesium sulphate were clean up matrix. estimate for limit quantification (LOQ) 0.01 mg/kg, average percent recoveries ranged 83.67–89.00. half-life estimated 1.72 days. Based on against insect residue status fruits, it can concluded that utilized ecosystem successfully manage pest complex without posing any health risks consumers.
