【摘要】 四年试验结果表明,用三唑酮拌种对防治小麦秋苗条锈病,压低田间菌量都有显著作用。这对控制越夏区(包括传播桥梁地带)的菌量保护广大麦区具有实际意义;对翌春条锈病有控制流行的作用,可推迟暴发期8～15天,保产效果为6～15.6％。试验结果还说明,拌种对翌春条锈病的控制作用,是在于压低初始菌量。因此拌种方法,适用于春季菌源以当地为主的地区,适用于春季流行的关键因素是越冬菌量的地区,并且处理的范围越大,越彻底,效果越好。还讨论了用拌种防治秋苗叶锈病和白粉病的作用。更多还原

【Abstract】 The results of the 4 Years’experiments indicated that the seeddressing by Triadimefon was very effective against the yellow rust ofwheat,reducing the pathogen up to over 90 percent in autumn,post-poning 8～15 days for "the rust explosiveness" and taking high yeild as6～15.6 percent in next year.The function of seed dressing is to pressdown the original source of infection.Therefore this method suit to ap-ply in the places where the inoculum overwintering is the most impor-tant factor for the spring epidemic of the rust.The larger the range ofthe treatment is,the better the effect will be.Seed dressing by Tria-dimefon also got satisfactory control against leaf rust and powdery mildewof wheat.更多还原
