恶苗病、干尖线虫病是水稻上主要的种传病害,在沿江地区均有发生,近两年水稻恶苗病有重新抬头加重的发展趋势,特别是代育秧和直播稻田,由于未浸种或浸种技术不到位的田块,秧田期即有病株出现,全区水稻中后期恶苗病的显症田块较往年都有大幅度的上升,对产量损失较大,成为影响水稻高产稳产和增产增收的主要影响因素之一。因此,切实做好稻种药剂处理是有效控制恶苗病、干尖线虫病发生为害
Bakanae and dried-tip nematodes are the major disease-causing diseases in rice and have occurred in the areas along the Yangtze River. In recent two years, the development of Bakanae disease has the tendency to increase again, especially the generation of seedlings and direct-seeding rice fields. Or seed soaking technology is not in place, seedling field that is sick, the region in late and late rice epidemic disease significant plots than in previous years have a substantial increase in yield loss, become a high and stable yield of rice And increase production and increase one of the main factors. Therefore, earnestly do a good job of rice seed treatment is effective control of diarrhea, dry tip nematode disease
