自有机氮和含汞、砷的农药问世以来，人们不加节制地滥用这些农药，造成严重的环境污染。这些农药毒性大，化学性质稳定，不易降解，残留时间长，易产生抗药性。近年来，科学家提出了“环境相容性农药———剂型———使用技术”的概念，对农药的用量、剂型和喷洒技术以及设备 Since the advent of organic nitrogen and pesticides containing mercury and arsenic, people have indiscriminately abused these pesticides and caused serious environmental pollution. These pesticides are toxic, chemically stable, not easily degraded, long-lived, easy to produce resistance. In recent years, scientists put forward the concept of “environmentally compatible pesticide --- dosage form --- using technology”, and the dosage, dosage form, spraying technology and equipment of pesticide
