Evaluation of Bio-intensive module for management of major insect pests of Groundnut

Field efficacy of two modules tested during December 2011 to March 2012 for the management of major insect pests of groundnut revealed that bio-intensive module for groundnut [vermicompost 2 t/ha + neem cake 250 kg/ha + bio-fertilizers 2 kg/ha + NPK (8.5:34:54 kg/ha); Chrysoperla zastrowi @ 50,000 eggs/ha (3 releases on 20, 30, 40 DAS); Trichogramma chilonis + T. japonicum @ 6.25 cc/ha (3 releases on 37, 47, 57 DAS); Helicoverpa armigera NPV and Spodoptera litura NPV @ 500 ml/ha (4 sprays 40, 50, 60, 70 DAS); neem gold 0.15% @ 1.5 ml/lit (4 sprays 25, 40, 55, 70 DAS)] was effective in reducing the incidence of both the sucking pests (aphids & leafhopper) and defoliators (leafminer, S. litura & H. armigera) of groundnut and recorded the highest yield of 1836 kg wet pods/ha.
