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.Keywords

A field experiment was conducted to compare various weed management strategies in onion atVegetable Research Farm, C.S.A. University of Agriculture and Technology, Kalyanpur, Kanpur during Rabi season in 2016- 2017. The experiment comprised of six treatments of pre-emergence and post-emergence of herbicides, their combination with hand weeding, mechanical or physical weed control and weedy check. The significant results revealed that pre-emergence application of oxyflurofen 23.5 % EC before planting + one hand weeding at 40-60 days after onion seedling transplanting recorded the higher marketable and total bulb yield (22.50 and 25.34 t ha-1, respectively) with maximum weed control efficiency of 87.02%.The same treatment was also recorded higher cost benefit ratio of 1:2.86. However, this treatment was economically viable for control of weeds in case of labour scarcity with better bulb yield, weed control efficiency, benefit cost and keep the weed density lower level in Rabi season grown onion production under central U.P. conditions.Keywords
