Mir, M: Efficacy of Certain Bio Pesticides on Different Crop

Vegetable are considered " Protective supplementary food" as they contain large quantities of minerals, vitamins and essential amino acids. The practical application of IPM in vegetable cultivation is generally still limited, although simple packages do exists for some key pests. Several insect pests and their natural enemies exist in the vegetable cropping system. The delicate balance between these two groups is disrupted largely due to injudicious use of insecticides Presently the management of these pests relies solely on the use of synthetic insecticides. But injudicious use of these insecticides has resulted in the development of resistance problem and environment pollution therefore, because of unique properties of specifically, safety and biodegradation; microbial insecticides are an attractive alternative to chemical insecticides in insect pest management system. Moreover, the development of resistance to chemical insecticides and concern over the deleterious effects of chemicals on environmental and human safety have provided a strong impetus for the development of microbial control agents for use in integrated controls of these insect pests.
