Management of Fruit and Shoot Borer, Leucinodes orbonalis (Guenee) in Brinjal through Sequential Application of Selected Insecticides and Biorationals

Abstract

Leucinodes orbonalis Guenee (Lepidoptera: Crambidae), commonly known as brinjal shoot and fruit borer is a dreaded pest in India. The bio efficacy of insecticides and biorationals has been test verified in managing fruit and shoot borer through logical sequential schedules. The results of the present field experiment conducted during Summer 2023 in Agricultural and Horticultural research Station (AHRS), Bavikere revealed the most effective insecticidal schedule among the tested sequences. The sequence containing Chlorantraniliprole 18.5 SC @ 0.3 ml/L - Spinosad 45 SC @ 0.4 ml/L - Lufenuron 5 EC @ 1.0 ml/L - Bacillus thuringiensis var. kurstaki @ 2.0 g/L demonstrated remarkable success in reducing the damage caused by L. orbonalis along with economic viability and high cost-benefit ratio.
