中国水稻稻曲病研究进展

Research advances in rice false smut(Ustilaginoidea virens) in China

稻曲病的发生不仅造成水稻产量损失,而且对人畜健康安全产生威胁。本文综述了中国建国以来稻曲病的发生分布与危害、生物学特性、主要影响因素、防治技术及国内研究报道情况,提出生产上迫切需要解决的难题:一是稻曲病的发生规律,二是防治稻曲病的高效安全药剂及其关键应用技术。

The occurrence of rice false smut not only causes yield loss,but also brings a threat to human and animal health and safety. The paper summarized the studies on the disease in the following aspects： distribution and damage,biological characteristics,major influencing factors,prevention and control. Besides,the paper raised two issues in rice production,the occurrence rule of rice false smut,and the efficient and safe agents controlling rice false smut and the key application technology.
