茎叶处理剂,又叫芽后处理剂,即将除草剂用水稀释后,直接喷洒到已出土的杂草茎叶上,通过茎叶吸收和传导消灭杂草。茎叶处理主要是利用除草剂的生理生化选择性来达到灭草保苗的目的。在花生出苗后,用药剂处理正在生长的杂草。此时药剂不仅接触杂草,同时也接触作物,因此要求除草剂应具有选择性。 Stem leaf treatment agent, also known as post-treatment agent, the herbicide is diluted with water, sprayed directly to the weeds have been unearthed stems and leaves, absorption and conduction through the stems and weeds to eliminate. Stem and leaf treatment is the main use of the physiological and biochemical selectivity of herbicides to achieve the purpose of extinguishing grass seedlings. After the emergence of peanuts, the growing weed is treated with the agent. In this case, the agent not only touches the weeds but also contacts the crop, and therefore, the herbicide is required to be selective.
