摘要：  三唑類殺菌劑是目前最具開發應用潛力的殺菌劑之一。本文通過采用菌絲生長速率測定法：將供試菌在含藥PDA平板培養基上進行培養,1d~5d后檢查各處理菌生長情況。用十字交叉測菌落直徑，并計算菌落擴展直徑及抑菌率，求出并比較了三唑酮 ，腈菌唑，戊菌唑，戊唑醇這四種三唑類殺菌劑及其金屬絡合物對幾種重要植物病原菌的毒力EC50,最后進行了盆載防效實驗。結果表明：這四種三唑類殺菌劑絡合金屬離子后藥效沒有明顯增強，與原藥比較相對平均，整體有增強趨勢。

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.
