全国农业技术推广服务中心2012年组织河北、山西、江苏、浙江、山东、河南、湖北、湖南、广东、四川、新疆等16个省(区)76个抗药性监测点,分别对稻飞虱、二化螟、棉铃虫、棉蚜、小菜蛾、小麦赤霉病等农作物重大病虫的抗药性进行了监测。结果表明,部分病虫对一些田间常用防治药剂抗药性水平显著上升,亟需优化防治策略,加强科学用药,抓好技术指导,开展统防统治,降低农药使用风险,减少生产成本。一、水稻褐飞虱、二化螟抗药性快速上升。在南方水稻主
The National Agricultural Technology Extension Service Center organized 76 drug resistance monitoring points in 16 provinces (autonomous regions and municipalities) in Hebei, Shanxi, Jiangsu, Zhejiang, Shandong, Henan, Hubei, Hunan, Guangdong, Sichuan and Xinjiang in 2012, Chilo suppressalis, cotton bollworm, cotton aphid, diamondback moth, wheat scab and other major pests and diseases of crops were monitored. The results showed that some pests and diseases had a significant increase in the resistance level of some commonly used pesticides in the field, and the prevention and control strategies were urgently needed to be optimized. Scientific and technical guidance, prevention and control, prevention and control of pesticides should be optimized to reduce production costs. First, the brown planthopper, Stem Breather resistance increased rapidly. The main rice in the south
