Management of Major Insect Pests and Diseases in Groundnut through IPDM Modules

The present investigation is undertaken to demonstrate the integrated pest and disease management modules in Groundnut (Arachis hypogaea L.). Groundnut is not only an important oilseed crop in India but also an important agricultural export commodity. Groundnut cultivation is often subjected to significant yield losses annually due to biotic and abiotic stresses which are the major limiting factors for attaining high productivity. In recent years, the management of groundnut pests and diseases through integrated pest and disease management (IPDM) solutions has gained prominence due to the vulnerable effects of pesticides. The field trials were conducted to evaluate the IPDM modules for the management of major insect-pests and diseases in Groundnut during 2016-17, 2017-18, and 2018-19 in kharif season at the Experiential Farm of Oilseeds Research Station, Jalgaon. Among the six modules tested, the module, seed treatment with Carbendazim + Mancozeb @ 2 g/kg seed + Need-based spray of Dimethoate 30 EC @ 1.5 ml/L + Need-based spray of Quinalphos 25 EC @ 2 ml/L for defoliator 50-70 DAS + Need-based spray of Propiconazole 25 EC @ 1 ml/L at 50-70 DAS recorded significantly highest seed germination (87.68 %), the significantly lowest incidence of collar rot (8.09 %), stem rot (10.58 %), significantly lowest Percent Disease Index( PDI) of early leaf spot (20.84 %), late leaf spot (39.35 %), rust (28.75 %), significantly lowest per cent leaf damage due to Leaf hopper (1.86 %), Thrips (2.13 %), and Spodoptera (2.11 %), respectively, moreover this module also showed significantly highest pod (1441.67 kg/ha) and haulm yield (4303 kg/ha) as compared to rest of the modules. It can be inferred that, under current conditions, implementing IPDM practices in groundnut production could result in a greater economic advantage. This should persuade more farmers to implement IPDM practices in groundnut.
