受境外虫源迁入量大,降水频繁等多重因素影响,今年水稻重大病虫比往年严重。据全国农作物重大病虫测报网监测,今年水稻重大病虫已累计发生3.5亿亩次,同比增加21%。其中,稻飞虱已累计发生1.1亿亩次,同比增加76%,而且田间虫量上升之快为近5年罕见,长江流域以南大部稻区呈大发生态势,湖南,贵州,四川等部分稻区为近20年来最重年份。市场人士分析认为,因病虫害范围的扩展,预计2012年全国农药市场需求将保持旺盛。除草剂占农药市场的半壁江山,销售额占到全球农药销售额的42%。而草甘膦是第一大类除草剂,一直占据着全球农药销售榜的首位。近期,草甘膦价格持续上涨,目前价位约为26500元/吨,较年初上涨
Affected by the large inflow of foreign insects and the frequent precipitation and other multiple factors, this year’s major pests and diseases of rice are more serious than in previous years. According to the National Crop Insect and Pest Monitoring Network Report, a total of 350 million mu of major pests and diseases have been reported this year, an increase of 21% over the same period of last year. Among them, planthopper has occurred a total of 110 million mu times, an increase of 76%, and the rapid increase in the field of insects in the past five years rare, most of the south of the Yangtze River valley showed a big trend, Hunan, Guizhou, Sichuan and other parts The rice area is the heaviest year in nearly 20 years.
