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.

Abstract

Mineral elements are applied to improve the plant health and yield. Host nutrition plays a crucial role in the outcome of the interaction between plants and pathogens. Though resistance and susceptibility are controlled genetically, a minor change in the nutritional status of the plants can have a considerable effect on severity of the disease. Mineral nutrition plays a very important role in the prevention of plant disease. Balanced plant nutrition promotes plant vigour providing tolerance to pathogen infection, improve physiological resistance to pathogen and affect the pathogen growth and multiplication. Although disease cannot be totally eliminated by any particular nutrient, the severity of the disease can be greatly reduced by manipulating the mineral nutrition of the plants. The present paper reviews thematically the role of nutrients in such management of diseases. Growers must use proper fertilizer programs, based on soil tests, plant analysis and disease monitoring.
