德化县山药炭疽病药剂防治技术研究

Chemical Control Technology for Yam Anthracnose in Dehua County

在山药炭疽病发生初期,选用5种杀菌剂防治山药炭疽病田间药效试验。结果表明:15%苯醚甲环唑+15%丙环唑(翠苗)防治山药炭疽病效果最好,且持续期较长,药后7、14d防效分别为84.8%、83.9%;45%咪鲜胺(增鲜)、10%苯醚甲环唑(凯高)也具有较好的防治效果;可在生产上作为防治山药炭疽病药剂,合理轮换使用。

In the early stage of yam anthracnose, five kinds of bactericides were selected to control yam anthracnose in field. The efficacy trial results showed that 15 % difenoconazole＋ 15% propiconazole （Cuimiao） had the best effect on preventing and controlling yam anthracnose with a longer persistence, the control efficacies for which were 84.8% and 83.9 % after 7 d and 14 d treatment, respectively. 45 % prochloraz （Zengxian） and 10 % difenoconazole （Kaigao） also had better control effect, and could be used as chemical agents for yams anthracnose prevention, alternatively.
