纹枯病是水稻生产上的主要病害之一。井冈霉素是长期用于水稻纹枯病防治的主要药剂,使用30多年来,纹枯病对该药的抗药性有所上升,部分稻区可能出现了抗性很强的病菌;又因其控制纹枯病的持效期一般只有7天左右,在大发生年份或者发病重的田块,需要多次用药才能取得较好的防治效果。因此,可以考虑采用其他有效药剂。满穗(240克/升噻呋酰胺悬浮剂)杀菌机理与井冈霉素和唑类杀菌剂不同,主要是抑制病原真菌三羧酸循环中的琥 Sheath blight is one of the major diseases in rice production. Jinggangmycin is a long-term main agent used for the control of rice sheath blight. After 30 years of use, the resistance of the sheath blight to the drug has risen, and some of the rice may have highly resistant bacteria. Sheath blight control the persistence period is generally only about 7 days, in the year of occurrence or the incidence of heavy plots, need multiple drug use to get better control effect. Therefore, consider the use of other effective agents. Full spike (240 g / L thifluzamide suspension) bactericidal mechanism and Jinggangmycin and azole fungicide is different, mainly inhibit the pathogenic fungi in the tricarboxylic acid cycle
