水稻稻螟蛉以往发生较轻,近年来随着农田生态环境的变化和农药品种结构的替换,目前已上升为水稻上的主要害虫。在早稻后期和晚稻前期,稻螟蛉均能发生,尤其是晚稻秧苗叶为害率一般达10～30%,严重的可达100%。为此,我们根据市场药源情况,对稻螟蛉进行了不同药剂防治效果的试验。 In the past, the occurrence of rice borer was relatively light. In recent years, with the change of farmland ecological environment and the replacement of the structure of pesticides, it has risen to the main pest on rice. In late rice and late rice, rice borer can occur, especially late rice seedling leaf damage rate is generally 10 to 30%, severe up to 100%. To this end, we conducted experiments on the control effects of different pesticides on rice stem borer according to the market source of medicine.
