摘要
为明确纳米杀菌剂对 2 种苹果叶部病害的防治效果,采用田间试验的方法,系统评价了几种纳米杀菌剂和同种常规杀菌剂以相同有效成分含量施药对苹果黑星病和斑点落叶病的防治效果.结果表明,纳米杀菌剂 15%苯甲·吡唑酯 ME 对苹果黑星病的防治效果最好,第 7 次药后 15、30 d 防治效果分别为 83.58%和59.37%,较常规杀菌剂提高.纳米杀菌剂 7%多抗·戊唑醇 ME对苹果斑点落叶病的防治效果最高,第 7 次药后15、30 d防治效果分别为 97.07%和 74.56%,较常规杀菌剂高.因此,在以相同有效成分含量施药时,纳米杀菌剂对 2 种苹果叶部病害的防治效果总体优于常规杀菌剂,可在生产上推广使用.
Abstract
In order to clarify the control effect of nanofungicides on two apple leaf diseases,the control effects of several nanofungicides and the same conventional fungicides with the same active ingredient content on apple scab and apple alternaria leaf spot were systematically evaluated by field experiments.The results showed that the nanofungicide 15%benzopyrazole ester ME had the best control effect on apple scab,and the control efficiency was 83.58%and 59.37%on 15 and 30 days after the 7th treatment,respectively,which was higher than that of conventional fungicides.The nanofungicide 7%polyanti-tebuconazole ME had the highest control effect on apple alternaria leaf spot,and the control efficiency was 97.07%and 74.56%on 15 and 30 days after the 7th treatment,respectively,which was higher than that of conventional fungicides.Therefore,when the pesticides were applied with the same active ingredient content,the control effect of nanofungicides on the two apple leaf diseases was generally better than that of conventional fungicides,and they could be popularized and used in production.
