玉米黏虫田间药剂筛选试验

The Experiment of Field Pesticides Screening on Mythimna Separata(Walker)

对玉米黏虫[Mythimna separata(Walker)]进行了田间药剂筛选试验。结果表明,阿维·氯苯酰和甲维盐对玉米黏虫的田间防治效果较好,且安全性较高,适合推广使用;此外,通过测产发现,前期(大喇叭口期及之前)黏虫为害重的地块,若能选对药剂,及时展开防控措施,产量可恢复70%左右。

The experiment was conducted to screen the field pesticides against Mythimna separata（Walker）,the results showed that,abamectin·chlorantraniliprole and emamectin benzoate had good control efficiency on M. separata（Walker）,with high security to popularize. Otherwise,by yield monitoring,if the right medicine was chosen and sprayed in time,the corn plants with hard damaged early could recover 70 percent of the production.
