高渗酮增效农药制剂对棉铃虫幼虫室内杀伤力试验研究

Studies on antipersonnel force test of gaoshentong synergized insecticides controlling the larvae of cotton bollworm in laboratory

:用高渗酮增效的四种不同的高渗农药制剂在室内对棉铃虫幼虫的杀伤力进行了试验。结果表明 :高渗酮对农药具有显著的增效作用 ,加有高渗酮的农药可使用药量减少 5 0 %以上 ,而对棉铃虫幼虫的杀灭率明显提高。另外也表明

Antipersonnel force of four types of high penetrating insecticides controlling against the larvae of cotton bollworm was tested in laboratory. The results showed that Gaoshentong had an excellent synergistic action on the tested insecticides, and can reduce over 50% of dosage of active ingredient at the same control level. The rate of knockdown to larvae of cotton bollworm was obviously raised. The experiments further showed that Gaoshentong was better than Dantong in the respect of insecticidal synergism.
