6种杀菌剂防治剑麻茎腐病田间药效试验

对6种防治剑麻茎腐病的杀菌剂进行田间药效筛选试验，结果表明：防治效果最好的是50％咪酰胺锰盐可湿性粉剂和10％苯醚甲环唑水分散粒剂，防效达60％以上；其次是40％硫磺·多菌灵悬浮剂和7．5％氟环唑乳油，防效均为573％；而40％五硝基多菌灵可湿性粉剂和3％甲基多抗霉素可湿性粉剂防效最差，防效低于40％。通过药剂防效和成本分析，建议生产上可使用50％咪酰胺锰盐可湿性粉剂、10％苯醚甲环唑水分散粒剂和40％硫磺·多菌灵悬浮剂交替使用防治剑麻茎腐病。...

Six kinds of sisal stem rot fungicide were used during the field efficacy screening experiment. The results showed that the field efficacy of 50% prochloraz manganese salt WP and 10% Difenoconazole WG were best, the control efficiency were more than 60%; followed by 40% of the sulfur .carbendazim SC and 7.5% Epoxiconazole EC, the control efficiency was 57.3%; However, the control efficiency of 40% the five nitro badistan WP and 3% methyl antimycin WP were loewer, the control effect was less than 40%.
