摘要：  三唑类杀菌剂是目前最具开发应用潜力的杀菌剂之一。本文通过采用菌丝生长速率测定法：将供试菌在含药PDA平板培养基上进行培养,1d~5d后检查各处理菌生长情况。用十字交叉测菌落直径，并计算菌落扩展直径及抑菌率，求出并比较了三唑酮 ，腈菌唑，戊菌唑，戊唑醇这四种三唑类杀菌剂及其金属络合物对几种重要植物病原菌的毒力EC50,最后进行了盆载防效实验。结果表明：这四种三唑类杀菌剂络合金属离子后药效没有明显增强，与原药比较相对平均，整体有增强趋势。

Abstract：Triazoles is one kind of fungicides that is the most potential application at present.  This article through uses the hypha growth speed measuring method: take zhe testing-fungus on zhe potato dextrose agar plate which inclusioning medicament progress train. For about one to five days ,examine each treating fungus’ growth complexion .The average colony diameter measured in two perpendicular directions was used for calculation of colonies expand diameter and bate thalli rate ，then account out and compare with tradimefon, myclobutanil, penconazole, tebuconazole which of zhe four kinds triazoles fungicides and theirs metal-composite that to several important plant causing fungus of disease of the Virulence namely 50% effective concentration . The control effect in pot test was conducted at zhe last. The results show that zhe four kinds triazole fungicides compare with primary medicament opposite average and the control effects are in general enhanced after the formation of the triazole fungicides with metals compared with ligands.
