水稻恶苗病和干尖线虫病均为种传病害。过去曾使用石灰水和多菌灵等来防治恶苗病,用盐酸和巴丹等防治干尖线虫病,不仅成本高,操作不便,而且对稻种发芽也不安全。我县于1992年筛选出可防治两种病害的新药剂——二硫氰基甲烷(商品名称为浸种灵)。具体防治技术为:将10％二硫氰基甲烷乳油,兑水稀释5000倍,浸泡稻种3～5天即 Rice Bakanae and dried-tip nematodes are all pathogenic diseases. In the past, lime water and carbendazim were used to prevent and treat diarrheal disease. Hydrochloric acid and baran were used for the prevention and treatment of dry tip nematodes. They are not only costly and inconvenient to operate but also insecure to rice germination. In 1992, our county screened a new agent that can prevent both diseases - dithiocyanomethane (trade name soaking Ling). Specific prevention and treatment techniques: 10% dithiocyanate methane EC diluted 5000 times diluted with water, soaked rice 3 to 5 days
