水稻恶苗病,是水稻重要病害之一。用汞制剂处理水稻种子有良好防治效果。但汞制剂稳定性强,不易分解,人畜能造成累积性中毒,现已停止使用。鉴于目前防治水稻恶苗病的有效药剂尚少,从1973年开始,我们在室内试验证明多菌灵防治恶苗病有效的基础上,又在省水稻研究所、沈阳市八一公社、辽阳市沈旦公社进行了用多菌灵防治水稻恶苗病的大面积示范。试验、示范证明,多菌灵防治水稻恶苗病,高效、经济、安全、使用方便。目前,沈阳等稻区每年应用面积近百万亩,现将试验示范结果介绍如下。
Rice Bakana disease is one of the important diseases of rice. Treating rice seeds with mercury preparation has good control effect. However, the stability of mercury preparations, not easy to decompose, humans and animals can cause cumulative poisoning, has now been discontinued. In view of the current effective control of rice Bakana disease is still small, from 1973 onwards, we laboratory tests proved that carbendazim effective control of the disease, but also in the Provincial Rice Research Institute, Shenyang Bayi commune, Liaoyang City Shendan commune with a large area demonstration of carbendazim control of rice Bakanae disease. Tests and demonstrations demonstrate that carbendazim can prevent and treat rice stump disease, which is efficient, economical, safe and easy to use. At present, Shenyang and other rice areas have an area of nearly 1 million mu each year. The results of the pilot demonstration are as follows.
