摘要
黑龙江省稻曲病的分布主要在南部地区，稻曲病的发生与不同年份的气象条件、小气候有关，７、８月份降雨量大、日照时数少、相对湿度大，稻曲病发生严重；不同水稻品种稻曲病发病程度不同。田间试验结果表明，在水稻孕穗期，喷施３０％ＤＴ和１５％粉锈宁可湿性粉剂，对稻曲病有较高的防治效果，可控制稻曲病的危害。
The distribution of false smut of rice (FSR) is south in Heilongjiang. The occurrence of false smut of rice (FSR) was related to the meteorologic condition of years, specific climate of fields. When it was more precipitation, less sunshine time and higher relative humidity during July - August, the occurrence of FSR was serious. There were differences of incidence of the disease among rice varieties. The control efficiency with sprays of 30% DT or 15% triadimefon WP at rice boot stage was higher, the damage of FSR could be controlled.
