Assessment of various IPM modules against major insect pests of pea (Pisum sativum L.)

Abstract

The present investigation was carried out during Rabi season of 2016-17 and 2017-18, at the Agricultural Research Farm of Institute of agricultural sciences, Banaras Hindu University, Varanasi, Uttar Pradesh on pea, to check the efficacy of integrated pest management modules against major insect pests of pea. To evaluate IPM modules field trial was conducted by using high yielding cultivar HUDP- 15 with five IPM modules with three replication in randomized block design, M1 - Pheromone trap, NSKE 5% Imidacloprid, M2 - Pheromone trap, Imidacloprid-Indoxacarb. Mustard is intercrop, M3 - Pheromone trap, Indoxacarb-Dimethoate, M4 - Sprayof Dimethoate- NSKE 5%, and M5– Untreated (control). The study revealed that highest cost: benefit ratio of 1:7.3 and 1:8.5 were obtained in the module 1 while Module 2 was found to have low cost: benefit ratio i.e., 1:3.2 and 1:3.9 during two consecutive years, though it was most effective in reducing pest population. Module 1 is found effective and economical.
