葡萄霜霉病·白粉病药剂防治试验简报

[目的]筛选能有效防治葡萄霜霉病和白粉病的药剂。[方法]在田间小区试验中，防治葡萄霜霉病设6种药剂，防治葡萄白粉病设3种药剂，于2种病害发生初期每隔7d施药1次，共施3次，施药后7～10d统计病叶率和病情指数，分析防治效果。[结果]6种药剂中，烯酰吗琳、灰霜特、金雷多米尔和灭菌成对葡萄霜霉病均有较好的防效，其中在霜霉病发生严重的地区，灰霜特防病效果最好，在发生较轻的地区，烯酰玛琳和金雷多米尔防效最好．其次为灭菌戍。供试的3种药剂均能较好地防治葡萄白粉病，在白粉病发病较为严重的地区，三唑酮防病效果最好，白粉病发生相对较轻的地区，阿米西达防治效果最好，其次为敌力康。[结论]该研究为这2种病害的防治提供重要的指导依据。
