摘要
为验证2016—2017年防控甘薯茎基部腐烂病害的试验结果,2018年选择了代森锰锌、多菌灵和农用硫酸链霉素3种杀菌剂,以不同浓度或其中2种杀菌剂混用,对甘薯茎基部腐烂病进行田间防控的验证试验。试验表明,选用的3种药剂对降低甘薯茎基部腐烂病的发病率有明显作用,并以多菌灵与代森锰锌或农用硫酸链霉素混合使用效果更好;多菌灵与代森锰锌、多菌灵与农用硫酸链霉素混合使用,增产幅度最高可达201.2%和178.0%,增产效果十分显著。该试验结果与此前的试验结果基本一致。
In order to verify the experimental results of preventing and controlling the rot disease at the base of sweet potato stem between 2016 and 2017,three fungicides including mancozeb,carbendazine and streptomycin sulfate for agricultural use were used in 2018 to verify the control of the rot disease at the base of sweet potato stem with different concentrations or a mixture of two fungicides.The results showed that the three reagents had an obvious effect on reducing the incidence of rot disease at the base of sweet potato stem.Also mixing carbendazim with mancozeb or with streptomycin sulfate for agricultural use had better effects and the increase in yield was up to 201.2%and 178.0%,indicating a significant increase in yield.The results of this experiment were basically consistent with those of previous experiments.
