Abstract

A field experiment were carried out for two consecutive Rabi seasons 2013-14 and 2014-15 at Student's Instructional Farm, N.D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P.). Among the various insecticides evaluated against brinjal shoot and fruit borer (L. orbonalis), Emamectin benzoate 5 SG @ 12.5g a.i./ha treated plots showed lowest infestation and gave higher fruit yield (253.12) followed by Flubendiamide 480 SC (249.33) and Novaluron 10 EC (243.63). The boipesticide NSKE 5 per cent most effective followed by Bacillus thuringensis, Verticellium lecanii and Beauveria bassiana. The highest cost: benefit ratio was obtained from NSKE 5 per cent (1:24.40) followed by Indoxacarb 14.5 SC (1:24.13) and Emamectin benzoate 5 SG (1:24.03) which were also economical than other treatments.

Abstract

An investigation were carried out identify their characteristics for susceptibility/ resistance against brinjal shoot and fruit borer (Leucinodes orbonalis Guenee.) infestation in Rabi season 2013-14 and 2014-15. Thirty eggplant germplasm/accessions were evaluated for resistance to shoot and fruit borer. Minimum mean infestation in shoot and fruits was found in genotype Punjab Sadabahar, PLR-1, DBR-31, NURBEE, NDB-3, PUSA PURPLE LONG, NDHB-2, NDHB-3 while maximum mean infestation in fruits was recorded in Swarna mani, BR-112.
