早在1980年美国学者Dolezal等报道在接种小区里用三唑酮处理种子可减轻全蚀病的危害,尤其是推迟播期结合种子处理防效最为显著。1986年英国的Baleman报道,用三唑醇处理种子后,尽管根系侵染并未减少,但与产量关系密切的白穗数明显降低。我国张慧杰等同志1994年撰文中提出在评价杀菌剂对小麦全蚀病的防效时,既要看其相对防治效果,又要考察白穗出现的时间。为了探 As early as in 1980, American scholar Dolezal et al. Reported that the treatment of seeds with triadimefon in inoculated plots could reduce the risk of total eclipse, especially the delayed sowing and seed treatment. In 1986, Baleman in the United Kingdom reported that after treatment of seeds with triadimenol, although the root infection did not decrease, the number of white spikes associated with yield was significantly reduced. Zhang Hui-jie and other comrades in our country put forward in evaluating the effectiveness of the bactericide on the eclipse of wheat in 1994, both on the relative prevention and control effects as well as on the appearance of white spike.
