Studies on ecofriendly approaches for the management of pulse beetle in chickpea

Abstract

The present investigation was conducted to evaluate the different plant based products against pulse beetle (Callosobruchus chinensis Linnaeus) in chickpea in the laboratory of Department of Agricultural Entomology, VNMKV, Parbhani-431 402 (M.S.), India during Kharif 2019-20. Among eight plant products evaluated, sweet flag rhizome powder @ 5% was significantly found superior in reducing 100 per cent mortality, no seed damage, no seed weight loss with highest seed germination (88.78%) followed by neem seed kernel powder @ 5% with higher adult mortality (88.33%), less seed damage (15.33%), less seed weight loss (4.71%) and higher germination percentage (76.67%) when seed stored for six month. Rest of the treatments viz., karanj seed powder @ 5%, neem leaves powder @ 5%, custard apple leaves powder @ 5% and karanj leaves powder @ 5% aslo showed less bruchid mortality(75.00, 65.00, 53.33, and 46.67%), seed damage (28.67, 42.00, 51.33 and 54%), weight loss (18.67, 20.07, 26.13, and 34.79%) and germination (62.67, 62.00, 58.67, and 53%). The seed treated with turmeric rhizome powder @ 5% was observed less effective in adult mortality (36.67%), seed damage (33%), weight loss (38.48%) and germination (44.67%) followed by tulsi leaves powder @ 5% (51.67, 66.33, 37.82 and 52.00), respectively Whereas, untreated seed was recorded significantly maximum seed damage (83.67%), seed weight loss (47.33%) with no adult mortality and minimum germination (37.00%) when it was stored for six month.
