Metabolism of Insecticides by Microorganisms

摘要: During the past 40 years use of agrochemicals including pesticides1 has contributed to a significant increase in major crop production. According an EPA report prepared by Lawless et al. (1975), there are at least 550 different pesticide chemicals commercially available United States alone. Moreover, about 8000 “formulations” sold on market and over 500 these products contain two or more “active ingredients”. Pesticide usage recent also increased dramatically, from 1.1 × 109 lb yr−1 1971 1.5 lbs end decade (Storck 1980). A prediction shows that worldwide expenditure pesticides will steadily U.S. $ 11.5 billion 1980 14.3 1985. The alone be spending nearly 4.5 year 1985 (Farm Chemicals 1981). Thus our environment remain under continuous pressure intensive applications massive quantities toxic chemicals.
