Abstract

Field studies were undertaken to assess the IPM module against insect-pests on chickpea. The pest population was lower in IPM field than Non IPM fields. The larval population of pod borer was recorded 2.67 MRL in IPM and 5.01 MRL in Non IPM. The Disease incidence was reduced in (8.96%) IPM than (13.77%) Non IPM field. The higher population of natural enemies (coccinellids, chrysoperla and predatory spiders) was observed under IPM fields. The parasitization in Helicoverpa larvae by Tachnid fly was increased in IPM (5.01 %) as comparison to Non IPM (2.67 %) field. The similar trend was found in parasitization of gram pod borer larvae by Campoletes sp. The adoption of IPM modules resulted minimized the number of chemical spray, i.e. 1.28 to 1.57 than 2.85 to 3.28 in Non IPM field. Timely dissemination of advisories and action has resulted in higher grain yield of 14.65 q/ha and lower pod damage 6.70 % as compared to non-IPM (12.15 %). The IPM module was ultimately the promising one with better net returns along with effective conservation of natural enemies even through Non IPM.
