Physical and Chemical Properties | Amber solid. Melting Point 65 °c. 25 ° C in water solubility <1mg/L, soluble in most organic solvents. Rat acute oral LD501500mg/kg. Rabbit acute percutaneous LD505000mg/kg. It is slightly irritating to the skin and eyes, and the LC50 for some fish is about 0.001~0.002mg/L. Formulations include emulsifiable concentrates and wettable powders. Herbicides. |
Use | It is used to control most of the broad-leaved weeds in the soybean field, and the dosage is 300g/ha. |
Toxicity | 乙羧氟草醚的低毒性,大鼠急性口服致死中量LD50为1500毫克/公斤,兔急性经皮LD50为5000毫克/公斤。可以简单理解为,如果大鼠按照50公斤计算,即大鼠需要吃150克折百的原药或者20%制剂750克才会死亡,兔子需要500克折百原药经过皮肤吸收才能死亡,但是这在现实生活中,是不可能存在的,所以乙羧属于低毒的药剂,并对鸟类低毒和鱼类也是低毒。但是它对皮肤和眼睛有轻度刺激作用。 |
