TO STUDIES ON INTEGRATED PEST MANAGEMENT AGAINST GRAM POD BORER (HELICOVERPA ARMIGERA HUB.) ON CHICKPEA (CICER ARIETINUM L.)

ABSTRACT A field experiment was conducted at Agriculture Research Farm of Raja Balwant Singh College, Bichpuri, Agra (U.P) during Rabi season of 2020-2021. The experiment was consisted of one variety of chickpea “ Desi Chana (40J14)”. Research was conducted to studies on integrated pest management against Gram pod borer (Helicoverpa armigera) on chickpea. Total two sprays were taken. The evaluation of different modules used for control of pod borer (H.armigera) best among all modules and found minimum larval population at one day before last spray , 3 , 7 and 12 days after last spray recorded with 5.04, 3.42 and 2.7 larvae per 10 plants , respectively . The lowest effective module was botanical intensive (Neemastra 3 E.C. @ 15ml/l. > Neem oil 0.15 E.C. @ 10ml/l. > Neem oil 0.15 E.C. @ 10ml/l.+ Neemastra 3 E.C. @ 15ml/l) with 4.80 , 4.56 and 4.32 larvae / 10 plants at one day before last spray , 3 , 7 , and 12 days after last spray , respectively and though it was found statistically superior to the untreated control.The results recorded on per cent pod damage revealed that all the modules were found significantly superior over control to reduce the per cent pod damage. The minimum pod damage of 5.68, 5.46 per cent pod damage per 10 plants was recorded in botanical Intensive module (Neem Oil 0.15 E.C. @ 10ml/l and Neemastra 3 E.C. @ 15ml/l) . The lowest pod damage of 4.67 per cent pod damage per 10 plants was recorded in Botanical module (Neem Oil 0.15 E.C. @ 10ml/l + Neemastra 3 E.C. @ 15ml/l) and though it was statistically superior to the untreated control (7.45 per cent pod damage per 10 plants).The highest chickpea grain yield (1449.27 kg/ha.) was recorded in treatment V1P1 (Neem Oil 0.15% E.C.+ Neemastra 3%), the minimum chickpea grain yield (966.18 kg/ha. , 908.21kg/ha.) was recorded in treatment V1P3 (Neem Oil 0.15%) and V1P2 (Neemastra 3%) and the lowest chickpea grain yield (444.44 kg/ha.) was recorded in Uncontrol plot V1P4 (Untreated plot)
