Abstract:

The study was conducted to assess the efficacy of some promising pest management tools against Brinjal Shoot and Fruit Borer (Leucinodes orbonalis Guenee) under field conditions during summer (February-August 2015). The tested tools were Rambo10 EC (Cypermethrin) @ 1ml L-1, Rekhaphos 20 EC (Chlorpyriphos) @ 2 ml L-1, Kinalux 25 EC (Quinalphos) @ 3 ml L-1, Suntec1.8 EC (Abamectin) @ 0.5 ml L-1 and Neem seed kernel extract (NSKE) @ 50 g L-1 of water and including coriander as barrier crop (cultural practice) and clipping off infested shoot and fruit (mechanical control) and an untreated control. The shoot infestation varied from 4.28% -12.65%. The lowest shoot infestation was recorded in Rambo10 EC treated plot (4.28%) which followed by Kinalux 25 EC (5.18%) and Neem seed kernel extracts (5.27%). The highest number of healthy (308.29) and the lowest number of infested (78.31) fruits plot-1 were harvested from Rambo10 EC treated plot and it increased and decreased the healthy and infested fruit over control 79.24% and 51.66%, respectively. Similarly, the highest healthy (21.58 kg) and the lowest infested (5.09 kg) fruit weight plot-1 was recorded from Rambo10 EC treated plot which increased and decreased the healthy and infested fruit weight over control 87.33% and 47.63%, respectively. The fruit yield ranged from 23.60 – 29.63 t ha-1. The yield increase over control was recorded in Rambo 10 EC, Kinalux 25 EC, Rekhaphos 20 EC, Suntec1.8 EC, Neem seed kernel extract, Coriander and mechanical (Clipping off) control 25.55%, 19.32%, 16.10%, 14.96%, 12.33%, 10.89% and 2.92%, respectively.
