由于农业科技的普及和化学工业的发展产生了大量的化学农用杀虫剂,化学杀虫剂的杀虫率高,成本低廉,因而应用广泛。但是化学农用杀虫剂都会使农副产品存在着不同程度的化学药品残留污染,它们对生物的直接或间接的毒副作用,致畸作用,致死作用,直接危害人类的健康,理想的杀虫剂应该是高效,低毒,无残留,无污染,价廉的天然杀虫剂。
Due to the popularization of agricultural science and technology and the development of chemical industry, a large number of chemical agricultural insecticides have been produced. Chemical insecticides have a high insecticidal rate and low cost, and are therefore widely used. However, chemical agrochemicals will cause the agricultural and sideline products to have varying degrees of chemical residue pollution, their direct or indirect biological side effects, teratogenic effects, lethal effects, directly endanger human health, the ideal pesticide should Is efficient, low toxicity, no residue, no pollution, cheap natural pesticides.
