咯菌腈对云南‘红地球’葡萄灰霉病防治效果评价

Evaluation of the effect of fludioxonil on gray mold of ‘Red Globe' grapevine in Yunnan area

近年来,葡萄灰霉病的发生越来越频繁,给葡萄种植户造成了很大的损失。葡萄对常规药剂的抗性凸显,所以筛选合适的灰霉病防治药剂的问题亟待解决。本文通过在设施和露天两种栽培方式下对咯菌腈防治葡萄灰霉病的效果进行验证。结果表明,40%咯菌腈2000倍和3000倍对葡萄灰霉病均有很好的防效,优于同等条件下50%啶酰菌胺和40%嘧霉胺,可以作为防治葡萄灰霉病的新型药剂进行推广使用。

In recent years, the occurrence of gray mold is more and more frequent, which has caused great losses to grape growers. Due to the conventional pesticides resistance on grape became seriously, so it is urgent to find some suitable controls against gray mold. In this paper, the control effects of gray mold were evaluated under faciliti es and field cultivation. The results showed that 40% fludioxonil had good control effect on gray mold at 2000 times and 3000 times, it was superior to 50% boscalid and 40% pyrimethanil under the same conditions. So fludioxonil can be widely used as a new kind of antiseptic for the control of grapevine gray mold.
