鱼藤根粉剂是以鱼藤属(Derris Lour.)植物的根部为主要有效成分配制成的粉末状制剂,其中植物鱼藤根(鱼藤酮含量为4%)在制剂中的含量为30%。鱼藤根粉剂是新型的植物源药剂,以撒施方法处理单个蚁巢,田间防控外来入侵红火蚁(Solenopsis invicta Buren)效果显著。按农药登记毒理学试验方法(GB 15670-1995),对鱼藤根粉剂进行了哺乳动物的基础毒性研究,结果显示:鱼藤根粉剂的急性经口和急性经皮毒性均为低毒级别,对皮肤为弱致敏物,对皮肤急性刺激为轻度刺激,对眼刺激为中度刺激,对皮肤和眼的刺激可分别在药后2 d和7 d恢复正常;鱼藤根粉剂的急性经口半数致死剂量(LD50)为2 710 mg/kg(♀)和2 370 mg/kg(♂),其95%可信限为2 000~3 690 mg/kg(♀)和1 420~3 950 mg/kg(♂),急性经皮LD50为大于2 000 mg/kg。
The root and shoot powder is a powdery preparation which is prepared from the root of Derris Lour. The root of the plant is prepared into a powdery preparation, wherein the content of the root of the tree (the rotenone content is 4%) is 30% in the preparation. Rhizoma Pinelliae Powder is a new plant-derived pharmaceutical agent. It is effective to deal with a single ant nests in the field with the prevention and control of Solenopsis invicta Buren. According to the pesticide registration toxicology test method (GB 15670-1995), the basic toxicological study on the powder of Radix et Rhizoma cinnabarinus was carried out. The results showed that the acute oral and acute dermal toxicity of Radix et Rhizoma Powder was low toxicity level, For the weak allergens, acute irritation to the skin mild irritation, moderate irritation to the eye irritation, the skin and eye irritation were returned to normal after 2 d and 7 d, respectively; The lethal doses (LD50) were 2 710 mg / kg (♀) and 2 370 mg / kg (♂) with 95% confidence limits of 2 000-3 690 mg / kg (♀) and 1 420-3 950 mg / kg (♂), acute percutaneous LD50 is greater than 2 000 mg / kg.
