Abstract

Seed protectants have an important role in enhancing the storability of the legume seed by protecting the legume seeds for long time against pulse beetle, Callosobruchus chinensis during storage. But some seed protectants fail to protect seed due to short residual effect . Due to short persistency on seed , the bruchids can survive and breed easily and maintain their population on stored even treated legumes, later on seed damage badly. Considering this point in view the residual toxicity of eight seed protectants (insecticides) were assessed in stored seed of pigeonpea at different storage periods under ambient condition N.D. University of Agriculture and Technology, Kumarganj, Faizabad. Novaluron 10 EC@ 0.05ml/kg seed had longer persistency on stored pigeonpea seed with maximum toxicity against bruchids upto nine month of storage followed by emamectin benzoate (Proclaim 5SG) @2ppm (40.0 mg/kg seed), indoxacarb (Avaunt 14.5 SC) @2ppm (13.8 mg/kg seed), profenofos (Curacron 50 EC) @2ppm (0.004ml/kg seed) and spinosad (Tracer 45 SC) @2ppm (4.4 mg /kg seed).

Abstract

A survey was conducted during July to December 2013 -2015 on the insect-pests and diseases incidence in rice eastern Uttar Pradesh of India. The crop is infested by many insect-pests which play a significant role in rice production. Insect-pests infest all parts of the plant at all growth stages, and a few transmit viral diseases such as leafhoppers and plant hoppers. In rice ecosystem some defender viz., dragon fly, spiders and praying mentis also were noticed. During the survey it was observed that the leaf folder and stem borer were found to be at significance level while Insect-pests as gall midge, gundhi bug, rice hispa, green leaf hopper, brown plant hopper, grasshopper etc. were also found at Rice field. Besides insectpests several diseases were noticed like ischolar_main-rot,brown rot, and sheathblight. A large number of insecticides have been tried for insect-pests management; indiscriminate use of pesticides has led to severe ecological consequences, residues in consumable products and ultimately resistance to the pesticides. The increasing concern for environmental safety and global demands for pesticide residue free food evoked keen interest in pest control through eco-friendly methods.
