摘要
用25% 敌力脱乳油、25% 顷止乳油、25% 富力库水乳剂和43% 大生富悬浮剂4种药剂进行香蕉叶斑病[CercosporamusaeZimm、Cordanamusae(Zimm)H觟hn、Helminthosporiumtorulosum(Syd.) Ashby]防治试验。结果表明:25%敌力脱乳油、25%顷止乳油和25%富力库水乳剂3种新型药剂对香蕉叶斑病的防效均较传统药剂43%大生富悬浮剂的防效高,持效期也较长;3种新型药剂中,25%敌力脱乳油的防效和持效性均表现最好,最高防效达84.80%,药后21 d防效仍达77.57%;4种药剂防治香蕉叶斑病的施药间隔期,25%敌力脱乳油为20～25 d,25%顷止乳油为12～15 d,25%富力库水乳剂为15～20 d,43%大生富悬浮剂为7～10 d。
The field trial was carried out to study the efficacy of 4 fungicides namely 25% EC propiconazol, 25% EC myclobutanil, 25% EW tebuconazole and 43% SC mancozeb on control of banana leaf spot diseases caused by Cercospora musae Zimm, Cordana musae (Zimm) Hohn and Helminthosporium torulosum (Syd.) Ashby in Chengmai, Hainan. The results showed that the control effects of new three fungicides propiconazol, myclobutanil and tebuconazole were better than that of common fungicide mancozeb and had a longer persistent duration. Of them, propiconazol had the best control effect (84.80%) and the longest persistent duration (77.57% after spraying 21 days). The intervals of application for the four fungicides were 20~25, 12~15, 15~20 and 7~10 days respectively.
