就目前的农业生产现状而言,化学农药仍然是降低农业病虫害防治劳动强度,有效防治病虫害,确保农业生产安全、高效和确保农产品优质丰产的重要手段。而内吸剂与触杀剂只是化学农药的两种杀虫灭菌形式。一、内吸剂内吸剂是指农药对害虫的毒杀形式内吸,即将药剂喷施到农作物上,药剂先被农作物根、茎、叶吸收,并在植株内迅速传播到植株的各个部位, 在农作物体内保持一定时期的毒效。当害虫取食农作物时,药剂随之进入害虫体内,使害虫中毒死亡, 从而达到保护农作物的目的。通过这种内吸作用, 杀死害虫的药剂就叫内吸剂。内吸剂有杀虫剂和杀菌剂两种:
For the current status of agricultural production, chemical pesticides are still an important means to reduce the labor intensity of agricultural pest and disease control, effectively prevent pests and diseases, ensure the safety and efficiency of agricultural production and ensure the high yield and quality of agricultural products. The internal respirator and touch agent is only two forms of pesticides and pesticides sterilization. First, the endosperm internal respirator Pesticide refers to the poisonous form of poison absorption, the forthcoming pesticides sprayed onto crops, pesticides first crop roots, stems, leaves absorbed and quickly spread throughout the plant to all parts of the plant , In the body of the crop to maintain a certain period of toxic effects. When the pests feed on the crops, the agents then enter the pests and cause the pests to poison and die, thus achieving the purpose of protecting the crops. Through this systemic action, the pesticide that kills the pests is called the endosuppressant. There are two types of insecticide and bactericide in the internal respirator:
