地下害虫是内蒙古地区小麦、大豆苗期的主要害虫,特别是金针虫和蝼蛄为害常造成缺苗断垄。使用辛硫磷处理种子,不仅有药害,且药效不够稳定,而3911又是限制使用的剧毒农药,因此筛选一种经济有效的防治地下害虫的新型杀虫剂很有必要。1991年受山西农科院植保所委托,在呼和浩特地区进行了10％辛拌磷粉粒剂防治小麦大豆地下害虫的药效试验。
Underground pests are the main pests of wheat and soybean seedling in Inner Mongolia, especially the insects of pinworm and slug are often caused by lack of seedlings broken ridge. The use of phoxim to treat seeds is not only phytotoxicity, and the efficacy is not stable enough, and 3911 is the limit of the use of highly toxic pesticides, so screening a cost-effective prevention and control of underground pests of new insecticides is necessary. Commissioned by the Institute of Plant Protection, Shanxi Academy of Agricultural Sciences in 1991, carried out in Hohhot, 10% synergistic phosphorus powder granule control of wheat and soybean underground pests efficacy trials.
