不同药剂处理对豫北地区秋延后设施辣椒病毒病防治效果分析OA
Analysis of the Control Effect of Different Chemical Treatments on Chili Virus Disease in Autumn Delay Facilities in Northern Henan Province
辣椒病毒病是制约辣椒产业稳定可持续发展的重要病害之一,为明确不同药剂处理对辣椒病毒病的防治效果,筛选出辣椒病毒病最优防治药剂,于2024年开展田间试验,以清水喷施为对照,设置2％香菇多糖可溶性液剂、5％氨基寡糖素水剂、31％寡糖·吗胍可溶性粉剂和20％吗胍·乙酸铜可湿性粉剂4种不同药剂处理,对比分析了不同药剂处理对辣椒生长、产量、经济效益和病毒病防治效果等方面的影响.结果表明:不同药剂对辣椒病毒病均具有良好的防治效果,其中以31％寡糖·吗胍可溶性粉剂处理防治效果最佳,达到87.81％,株高、茎粗、叶面积指数、产量和净收益最高,分别为65.89 cm、9.83 mm、3.122、69 106.39 kg·hm-2和95 249.85元·hm-2.因此,综合考虑病害防控效果、产量表现与经济性,推荐在豫北地区秋延后设施辣椒病毒病中,推广31％寡糖·吗胍药剂作为防治辣椒病毒病发生的高效绿色防控手段,本研究可为辣椒产业的绿色高效发展提供理论依据.
Chili virus disease is one of the important diseases that restrict the stable and sustainable development of the chili industry.In order to clarify the prevention and control effects of different chemical treatments on chili virus disease,the optimal control agent for chili virus disease was screened.Field experiments were conducted in 2024,with water spraying as the control.Four different chemical treatments were set up,including 2％shiitake mushroom polysaccharide soluble liquid,5％amino oligosaccharides water agent,31％oligosaccharides·metformin soluble powder,20％guanidine·copper acetate wettable powder.The effects of different chemical treatments on chili growth,yield,economic benefits,and virus disease prevention and control were compared and analyzed.The results showed that different pesticides had good control effects on pepper virus disease,among which 31％oligosaccharides·metformin soluble powder treatment had the best control effect,reaching 87.81％.The highest plant height,stem thickness,Leaf area index,yield,and net income were 65.89 cm,9.83 mm,3.122,69 106.39 kg·hm2,and 95 249.85 yuan·hm-2,respectively.Therefore,taking into account the effectiveness of disease prevention and control,yield performance,and economy,it is recommended to promote the use of 31％oligosaccharides guanidine as an efficient green prevention and control method for preventing and controlling pepper viral diseases in autumn delayed facility chili peppers in northern Henan.This study can provide theoretical basis for the green and efficient development of the chili industry.
