EVALUATION OF DIFFERENT ORGANIC PRODUCTS AGAINST PIGEONPEA PULSE BEETLE Callosobruchus chinensis L.

摘要

The two plant powders i.e. neem seed powder, vekhand powder @ 5 g/kg seeds and four vegetable oils i.e. Neem oil, castor oil, mustard oil, groundnut oil a 5 ml/kg seeds and one chemical treatment deltamethrin @ 0.04 ml/kg seeds tested each up to 120 days of storage against pulse beetle (Callosobruchus chinensis L.) infesting stored pigeonpea seeds. The treatment deltamethrin @ 0.04 ml/kg seeds recorded excellent surface protectants for pigeopea seeds in view of relatively, least number of eggs, adultemergence, per cent of seed damage, per cent of seed weight loss and highest germination. Among the plant products and oils treatments i.e. neem oil @ 5ml/kg seeds and vekhand powder @ 5 g/kg seeds are followed by deltamethrin @ 0.04 ml/kg seeds. The germination percentage of pigeonpea was notadversely affected due to any of the oils and plant products and also low cost was incurred for 100 kg seeds by the treatments with deltamethrin @ 0.04 ml kg, neem oil @ 5 ml/kg seeds and vekhand powder@ 5 g/kg seeds.
