本文选用5种杀菌剂进行硬毛刷涂药处理、3次重复的田间药效试验,观察5种杀菌剂防治花椒膏药病的田间药效。结果表明:43%戊唑醇悬浮剂2000倍液、25%苯醚甲环唑乳油2000倍液、25%丙环唑乳油1500倍液、70%百菌清可湿性粉剂800倍液和3%甲霜恶霉灵水剂500倍液对膏药病的防治效果分别为88.41%、82.16%75.25%、24.91%和25.68%,43%戊唑醇悬浮剂2000倍液、25%苯醚甲环唑乳油2000倍液和25%丙环唑乳油1500倍液对膏药病的防治效果明显好于70%百菌清可湿性粉剂800倍液和3%甲霜恶霉灵水剂500倍液对膏药病的防治效果;43%戊唑醇悬浮剂2000倍液的防治效果明显好于25%丙环唑乳油1500倍液,与25%苯醚甲环唑乳油2000倍液差异不显著;25%苯醚甲环唑乳油2000倍液和25%丙环唑乳油1500倍液对膏药的防治效果差异不显著。43%戊唑醇悬浮剂2000倍液和25%苯醚甲环唑乳油2000倍液可在产上使用。
In this paper, five kinds of fungicides were selected for brush coating, three repeated field trials were conducted to observe the efficacy of five kinds of fungicides in preventing and curing pepper plaster disease. The results showed that: 43% tebuconazole suspension 2000 times, 25% difenoconazole 2000 times, 25% propiconazole 1500 times, 70% chlorothalonil WP 800 times and 3% The control efficacy of 500 times solution of methamphetamine on plaster was 88.41%, 82.16%, 75.25%, 24.91% and 25.68%, respectively. The concentration of tebuconazole 43% was 2000 times and the content of difenoconazole EC 2000 and 25% propiconazole EC 1500 times on the prevention and treatment of plaster disease was significantly better than 70% Chlorothalonil WP 800 times and 3% Methamecetin 500 times the liquid agent on plaster The control effect of 43% tebuconazole suspension 2000 times liquid was obviously better than that of 25% propiconazole 1500 times emulsifiable concentrate, which was not significantly different from that of 25% diflunisal. The control effect of the plaster was not significantly different between the control group and the control group. A solution of 43% tebuconazole suspension 2000 times and 25% difenoconazole 2000 times liquid can be used in the production.
