   水稻是我国重要的粮食作物,也是遭受病虫害严重侵袭的作物,每年病虫害发生面积都在16亿亩次以上。水稻也是目前我国病虫防治用药量最多的作物,因此,推进水稻科学减量用药尤为重要。改变过去粗放的防治方式,科学使用高效、低毒农药品种,采取组合用药、减量用药和改进施药技术等,可以有效提高水稻科学用药防控水平。

  暂停用药。对病虫已产生高抗性的药剂和具有交互抗性的药剂必须暂停使用。如稻褐飞虱对吡虫啉已产生极高水平抗性,因此不宜用吡虫啉防治稻褐飞虱;浙江江苏湖南123彩票二化螟对杀虫单、三唑磷产生高至极高水平抗性的地区,暂停使用三唑磷、杀虫单防控二化螟。

  安全用药。稻田是个特殊的生态系统,天敌种类多,对害虫有良好的控制作用。要使用选择性农药,禁止使用敌杀死等对稻田天敌毒性大的农药品种,防止杀伤天敌及引发害虫再猖獗。
