Background technology

The sustainable development of agricultural is related to the overall situation of national economic development and social stability. Crop disease, worm, crop smothering etc. are the important biomolecule disasters of agricultural production. Being kind more than 2,300 according to made China harmful organism, these harmful organisms not only kind is many, widely distributed, and the complicated condition that causes disaster, occur frequently. If do not prevented and not treated, every year will loss total output of grain 15%, Cotton Gossypii 20%-25%, vegetable more than 25%. The annual actual production of China's pesticide about 400,000 tons, is only second to the U.S. according to second place of the world, annual consumption about 270,000 tons, at the forefront in the world. According to statistics, there is Pest organism Mus 4,400,000,000 mu time in the nineties China agricultural, preventing and treating area is 4,900,000,000 mu times every year on average, only to prevent and treat harmful organism calculating, namely the grain loss retrieved every year reaches more than 6,500 ten thousand tons, is equivalent to the grain ration (by 200 kilograms of calculating for each person every year) of 3.25 hundred million people. In the comprehensive control of biological epidemics, the level according to the development of current plant protection subject, chemical prevention remain most convenient, the most stable, most effective, the most reliably, the most cheap means of prevention. Especially when running into sudden, intrusion type biological epidemics and occurring, there is no any prevention and controls and can replace chemical pesticide, having chemical prevention only can prove effective. In a foreseeable future, agricultural production be unable to do without pesticide.

And along with the development of agriculture industrialization, the production of agricultural product is increasingly dependent on the allogenic materials such as pesticide, antibiotic and hormone. China's pesticide consumption on grain, veterinary antibiotics, Folium Camelliae sinensis remains high, and the unreasonable use of these materials will cause that the pesticide residues in agricultural product exceed standard, affect consumer's edible safety, consumer can be caused time serious to cause a disease, grow abnormal, even directly result in and be poisoned to death.Pesticide residues exceed standard also can affect the trade of agricultural product.

At present, through incomplete statistics, the pesticide variety of existing application has reached kind more than 100, although agricultural keeps good harvest volume increase play a significant role, but the irrational use because of pesticide, cause many environmental problems such as destroyed in farmland ecosystem, also results in the food-safety problem that can not be ignored.
