Comparative Studies of Seed Protectants for Longterm Ambient Storage of Mungbean against Callosobruchus chinensis (L.)

Abstract

A Comparative study was carried out to evaluate the newer insecticides and botanicals as seed protectants for long term ambient storage of mungbean (Vigna radiata (L.) Wilczek ) against Callosobruchus chinensis (L.) under ambient condition use Complete Randomized Design (CRD) at Seed Entomology laboratory of Seed Science and Technology, Acharya Narendra Deva University of Agricultural and Technology, Kumarganj, Ayodhya during 2019-2020. Sixteen included control newer insecticides and botanicals viz. Emamectin benzoate @ 40.0 mg/kg1 seed, Spinetorum @ 8.5 mg/kg-1 seed, Sivanto prime @ 0.01 ml/kg-1 seed, Karanj oil@ 5ml/kg seed, Castor oil @ 5 ml/kg seed, Sunflower oil @ 5 ml/kg seed, Mustard oil @ 5 ml/kg seed, Sesamum oil @ 5 ml/kg seed, Neem oil @ 5 ml/kg seed, Neemoz gold @ 5 ml/kg-1 seed , Coconut oil @ 5 ml/kg seed, Neem leaf powder @ 5g/kg seed, Neem kernel powder @ 5g/kg seed and Gorakhmundi powder @5g/kg seed as seed protectants along with Deltamethrin 2.8 EC @ 0.04ml/kg seed as check were tried to evaluated under ambient condition. Among tested seed protectants, Emamectin benzoate @ 40.0 mg/kg1seed followed by Sivanto prime @ 0.01 ml/kg-1 seed, Spinetorum @ 8.5 mg/kg-1 seed, Neemoz gold @ 5 ml/kg-1 seed and Karanj oil@ 5ml/kg seed was found most effective treatment against Callosobruchus chinensis (L.) due to least seed damage (1%) and weight loss (0.84%) with high germination percent (86.83%) in mungbean for long term (upto 6 months) under ambient storage condition.
