Abstract

The experiment was conducted under laboratory condition in the Department of Entomology, Acharya Narendra Deva University of Agricultural and technology, Kumarganj, Ayodhya to find out the eco-friendly management of pulse beetle, C. chinensis Linn. in stored chickpea cv; PG-186 seed under ambient condition by using some promising botanicals as seed protectant viz., neem oil @ 5 ml/kg seed, mustard oil @ 5 ml/kg seed, coconut oil @ 5 ml/kg seed, citronella oil @ 5 ml/kg seed, karanj leaf powder 5 g/kg seed, marigold leaf powder 5 g/kg seed, lemon grass leaf powder 5 g/kg seed, neem leaf powder 5 g/kg seed and deltamethrin 2.8 EC as check @ 0.04 ml/kg seed. Among tested all seed protectants besides chemicals, deltamethrin 2.8 EC; Neem oil @ 5 ml kg-1seed followed by Mustaard oil @ 5 ml kg-1 seed was found most effective botanical as seed protectant in due to less seed damage and weight loss with high germination percent i.e. above IMSCS upto 9 month of chickpea storage periods.
