1999年以来 ,上海郊区水稻病虫发生严重 ,水稻螟虫危害逐年上升 ,稻纵卷叶螟、白背飞虱暴发机率高 ,水稻条纹叶枯病突然猛增 ,稻瘟病、稻曲病潜在威胁大。通过准确地指导病虫防治 ,每年挽回粮食损失1.0 5～ 1.2 5亿kg ,但实际损失仍达 0 .0 8～ 0 .10亿kg。为了有效控制病虫危害 ,减少粮食损失 ,上海郊区一定要完善植保组织体系 ,进一步提高植保人员的技术水平 ,保证必要的病虫监测资金投入和工作条件 ,为上海郊区粮食丰收提供必要的保障基础。
Since 1999, pests and diseases of rice in the suburbs of Shanghai have been serious, and the damage to rice stem borers has been increasing year by year. The outbreak rates of rice leaf roller and white-backed planthopper are high, and the sudden threat of rice stripe blight suddenly increases. The potential threat to rice blast and rice false smut is large . By accurately guiding the prevention and control of pests and diseases, the annual grain loss is 1.05-1.25 billion kg, but the actual losses still reach 0.08-0.10 billion kg. In order to effectively control pests and diseases and reduce food losses, we must perfect the system of plant protection organizations in the suburbs of Shanghai, further improve the technical level of plant protection workers and ensure the necessary fund input and working conditions for pest and disease monitoring so as to provide the necessary guarantee for food supply in the suburbs of Shanghai .
