Evaluation and Validation of Different Integrated Pest Management Modules for Field Pea

Abstract

This research was carried out during rabi (November-March) 2020–21 at Agronomy Instructional Farm, S. D. Agricultural University, Sardarkrushinagar, Gujarat, India to evaluate the efficacy of seven different Integrated Pest Management (IPM) modules against insect-pests of field pea. Five IPM modules were tested for their efficacy against insect-pest. The result revealed that the module M₄ (Border crop with chickpea+treating seeds by imidacloprid 600FS @ 3 ml kg^-1 seed+yellow sticky trap @one module^-1+sprays of azadirachtin 1500 ppm @ 40 ml 10 l^-1 water+HaNPV 250 LE @ 10 ml 10 l^-1 of water+profenophos 50 EC @ 10 ml 10 l^-1 water) exhibited significantly minimum population of 1.47 aphid 10 cm^-1 shoot, 1.00 leafhopper trifoliate^-1, 0.62 whitefly trifoliate^-1, 0.08 larva plant^-1 with lowest pod borer damage (0.30%) and thus proved to be most effective module which was at par with module M₁. The highest field pea seed yield (1250 kg ha^-1) was also harvested from module M₄. The maximum (42.04%) increase in yield was obtained in the plots framed with M₄ followed by module M₁. The avoidable losses in field pea yield were minimum (9.36%) in module M₁. The highest (`Rs. 87,500 ha^-1) gross realization was obtained from the plots framed with module M₄. The highest Protection Cost: Benefit Ratio (PCBR) was obtained in module M₄ (1:3.56) which clearly indicated that module M₄ was also the most economical module amongst all.
