摘要
对6种药剂进行防治油菜霜霉病试验。结果表明:这6种药剂对油菜霜霉病均有一定的防治效果,其中72%甲霜.锰锌防效较好,且持续时间长,但速效性较差;80%烯酰吗啉速效性最好,且防效较高,持续时间较长,可以在生产上推广应用。
Six fungicides were tested to control the rape downy mildew. The results showed that all of the fungicides had control effects. The effect of 72% ridomil-MZ was better with long duration, while its quick efficiency was poor. The effect of 80% dimethomorph was the best with long duration, and its quick efficiency was good, which could be extended and applied in rape production.
