实验室、模拟现场和现场一系列试验结果表明,康其尔牌蟑螂克星对蟑螂具有击倒快、灭效高、持效长、性能稳定、安全低毒等特点。其1:9水溶液按国家标准圆筒法测定,对德国小蠊的KT50为2.3408min,24h死亡率为100%。按25ml/m2,50ml/m2剂量玻璃板滞留喷洒,16周时KT50分别为7.9206、5.2651min,72h死亡率仍达91.7%、98.3%;模拟现场按2或1ml/m3直接喷雾,其KT50分别为9.1979、12.1843min,72h死亡率分别为100%、98.9%;现场试验按25ml/m2一次施药,灭效达95.7~96.7%。康其尔牌蟑螂克星1:9水溶液对小白鼠急性经口LD50为6064.6mg/kg,对大白鼠急性经口LD50为10556mg/kg,对大白兔经皮LD50(♀)>975.6mg/kg,LD50(♂)>630.9mg/kg,大白鼠急性吸入LC50>11000mg/m3/2h,均属低毒,对大白兔眼、鼻无明显刺激症状。
The results of a series of experiments in laboratory, simulated field and on-site show that Kang’er Er brand cockroach nemesis has the characteristics of quick knockdown, high efficiency, long lasting, stable performance, low toxicity and safety to cockroaches. The 1: 9 aqueous solution was determined by the national standard cylinder method. The KT50 of German cockroach was 2.3408min, and the 24-hour mortality rate was 100%. After 25ml / m2 and 50ml / m2 dosages of glass plates, KT50 was 7.9206,5.2651min at 16 weeks, and still reached 91.7%, 98.3% at 72h. Simulated field was treated with 2 or 1ml / m3 direct spray, the KT50 were 9.1979,12.1843min, 72h mortality were 100%, 98.9%; field test by 25ml / m2 once application, the effect of 95.7 ~ 96.7% . Acute oral LD50 of Kangqier brand cockroach nemesis 1: 9 aqueous solution in mice was 6064.6mg / kg, acute oral LD50 in rats was 10556mg / kg, white rabbits percutaneous LD50 (♀)> 975.6mg / kg, LD50 (♂)> 630.9mg / kg, acute inhalation rat LC50> 11000mg / m3 / 2h, are low toxicity, no significant irritation to the eyes of rabbits.
