粘虫主要危害玉米、高粱、谷子、小麦、水稻等作物。过去防治粘虫常用粘虫散,残留量高,污染环境。而晶体敌百虫毒性低,药源充足,杀虫力高。应用晶体敌百虫配成毒土防治粘虫,可以省略喷粉需加填充料和喷雾要大量加水的工序等。晶体敌百虫毒土防治粘虫有很多优点:①杀虫效率高,在二、三代粘虫发生较重,虫口密度较大条件下,每亩用90%晶体敌百虫1.5～2两配制的毒土扬撒(或摅施)防治小麦、谷子、玉米上的粘虫,效果达95％左右。 The main infestation of armyworms is corn, sorghum, millet, wheat, rice and other crops. In the past, the control of armyworms commonly used in the control of armyworm powder, residual high, pollute the environment. The crystal toxicity of trichlorfon low, adequate source, high insecticidal power. Application crystal trichlorfon poison soil poisoning control armyworms, you can omit the need to add powder and spray to add a lot of water and other processes. Crystal trichlorfon poison soil prevention and control of armyworm has many advantages: ① Insecticidal efficiency, in the second and third generations of the occurrence of heavier armyworm, insect population density under the conditions of 90% per acre with trichlorfon 1.5 ~ 2 two preparation The poisonous soil Yansha (or Xun Shi) prevention and control of wheat, millet, corn on the armyworm, the effect of about 95%.
