[目的]进一步明确36%多·酮SC对安徽省小麦赤霉病的防治效果以及施用安全性。[方法]于2009和2010年在安徽省凤阳县进行了36%多·酮SC对小麦赤霉病防效的大田示范试验,设置5个处理,并对总效果进行差异显著性分析。[结果]36%多·酮SC用量1 800～2 100g/hm2对小麦赤霉病防治效果优于50%多菌灵WP,病穗率防效和综合病指防效均在75%以上。[结论]36%多·酮SC是目前防治小麦赤霉病替代高效农药的首选药剂。
[Objective] The research aimed to further clarify the control effect and application safety of 36% polyketone SC on wheat scab in Anhui Province. [Method] In 2009 and 2010 in Fengyang County, Anhui province, a field experiment was conducted on the control of wheat scab with 36% ketones SC. Five treatments were set up and the significant differences were analyzed. [Result] The control effect of SC with 1 800 ~ 2 100 g / hm2 was superior to that of 50% carbendazim WP with 36% multi-ketone SC dosage. The control effect of disease efficiency and comprehensive disease index were both over 75%. [Conclusion] 36% multi-Ketone SC is the first choice for the prevention and control of wheat scab.
