蒙古灰象(虫甲)是大豆苗期重要害虫,也危害玉米、高粱.生产上过去主要推广20%六六六粉拌种或毒土防治,对蒙古灰象(虫甲)效果不够理想.鉴于六六六停产,寻找取代药剂已成为极待解决的问题.为此我们进行了甲胺磷、甲基硫环磷防治蒙古灰象(虫甲)试验.结果如下: 1.50%甲胺磷乳油1∶5∶100或1∶10∶200闷种,35%甲基硫环磷1∶50∶150或1∶50∶300闷种,对大豆苗期害虫(蒙古灰象(虫甲)、网目砂潜)有良好防治效果.植株被害率、害虫死亡率及残效期调查指标均好于20%六六六拌种.其中甲基硫环磷闷种更佳,杀虫效果及残效期优于甲胺磷闷种.用两种药剂闷种,经济有效,且闷种的杀虫有效期与蒙古灰象(虫甲)的严重
Mongolian gray elephants (insects) is an important pest of soybean seedling, but also endangered corn, sorghum production in the past to promote the main 20% 666 powder seed or poison soil prevention and control, the Mongolian gray elephant (insects) effect is not ideal. In view of the suspension of production of 666, the search for an alternative medicine has become an issue that needs to be resolved. For this reason, we conducted methamidophos and methylthiophene to control the Mongolian gray elephant (Asclepiadus) test. The results are as follows: 1.50% methamidophos 1: 5: 100 or 1: 10: 200 boring species, 35% methylthiophosphorus 1:50: 150 or 1: 50: 300 bored species of soybean seedling pests (ashes, Sand loss potential) have a good control effect.The rate of plant damage, pest mortality and residual disease survey indicators are better than 20% 666 seed dressing, of which methylthioninium phosphorus is better, with insecticidal effect and excellent residual effect Methamidophos bored species. With two kinds of drugs nausea species, cost-effective, and the bulk of the insecticide expiration and Mongolian gray elephant
