关于内吸杀虫药剂 自1952年德国的希莱德(Schrader)发现几种有机合成杀虫药剂有内吸作用之后,内吸药剂已成为研究植物化学保护的重要方向。目前在研究杀虫药剂的先进国家里,都使用着很大的人力在研究新内吸药剂的合成、使用及其附带的问题。因此,最近几年以来内吸药剂的发展非常突出。 About systemic insecticides Since systemic absorption of several organic synthetic insecticides was discovered by Schrader in 1952 in Germany, systemic absorption agents have become an important direction for the study of phytochemical protection. At present, in the advanced countries where insecticide research is conducted, a great deal of manpower is being used to study the synthesis, use and problems attached to the newly introduced drug. Therefore, the development of systemic absorption agents has been outstanding in recent years.
