Bioefficacy of some plant products against brinjal (Solanum melongena L.) Shoot and Fruit borer, [Leucinodes orbonalis (Guenee)]

Author(s): Naveen Shanker Pandey and Sasya Thakur
Abstract: A field experiment was conducted to study the bioefficacy of some plant product against Brinjal shoot and fruit borer Leucinodes orbonalis on Brinjal during kharif season of 2016-2017.The experiment was conducted in the research field of Sam Higginbottom University of Agriculture Technology and Science, Allahabad. Total two sprays were applied to protect the crop from Leucinodes orbonalis with three replications. Neem leaf extract 0.5%, NSKE 2.5%, Garlic extract 5%, Pongamia extract 5%, Tobacco Leaf extract 1%, Leaf extract of lantana camara 1%, Cypermethrin 25 EC were evaluated against Leucinodes orbonalis infesting Brinjal. The observations on infestation of Leucinodes orbonalis 24 hours before (Pre-treatment) and 3, 7 and 14 days after treatment (Post-treatment) at each spraying were recorded for computing the infestation percent over control. The treatment with recommended insecticide Cypermethrin 0.2% was of the most effective treatment followed with and Neem leaf extract 0.5%, Pongamia 5%, NSEK 2.5%, Garlic extract 5%, Tobacco leaf extract 1.0%, lantana camara Leaf extract 5%. The treatments with Cypermethrin25 EC, and NSKE 2.5 %, Conc. also performed well against this pest. Neem leaf extract, Pongamia leaf extract, Tobacco leaf extract, Leaf extract of lantana camara and Garlic extract were found less effective against Leucinodes orbonalis. Cypermethrin 25 EC (1:11.85) followed by NSKE 2.5%, (1:10.13) Neem Leaf extract 5%, (1:9.67), Pongamia 5% (1:9.18), Tobacco leaf extract 1. 0%(1:8.60), Leaf extract of lantana camara (1:8.33),Garlic extract (1:7.90) untreated control (1:7.23). Among the treatments the highest cost benefit ratio (C:B ) of (1:11.85) was obtained with of. Cypermethrin 25 EC.
