摘要: 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。

Abstract: The CONTROL Cockroach-Killer was diluted with 9 times water, then, was used in the tests below.The test methods were all from the Guo-Biao. The tested cockroach was Blattella ger manica. The direct spray KT50 was 2.34mins, the mortality in 24hrs was100 percent. The residual effi cacy was tested on glass surfaces.At the doses of 25ml/m2, 50ml/m2, the KT50 in 16 weeks were 7. 92 mins,5.27 mins,the mortalities in 72 hrs were 91.7 percent,98.3 percent. In mock test at the doses of 1ml/m3,2ml/m3, the KT50 were 12.18 mins and 9.20 mins,the mortalities in 72hrs were 98.9 percent and 100 percent. In field test at the dose of 25ml/m2, the mortalities were 95.7 percent and 96.7 per cent.The LD50( acute oral toxicities) was 10556mg/kg against wistar rats. The LC50 was over 11000mg/m3.2hrs.The LD50(♀),LD50(♂) were over 975.6mg/kg and over 630.9mg/kg against rabits.There were no significant reactions to eyes and noses.
