三株不同镰刀菌对甘薯致病性及7种杀菌剂敏感性测定
Research on Three Different Strains of Fusarium spp.of Pathogenicity to Sweet Potato and Sensitivity Test to Seven Kinds of Fungicides
摘要
Abstract
The toxicity of 7 fungicides against three different strains of Fusarium spp.was detected by the meth-od of mycelium growth inhibition for plant disease controlling and breeding .The result showed that ,Bacillus subtilis WP had the best control effect to the three Fusarium spp.with the best EC50 as 0.002 3 μg/mL.Difenoconazole . propiconazole and hexaconazole had better control effect to 12 Z-1 and 12 Z-2 with EC50 between 0 .002 5 μg/mL and 0.86 μg/mL,and EC90 between 11.01 μg/mL and 46.48μg/mL than 12Z-3 with EC50 as 1.54 μg/mL and 12.36 μg/mL,and EC90 as 1 893.29μg/mL and 1 101.14μg/mL respectively.With the needle-sticking method, we found that among the four different sweet potato varieties ,Yanshu 25 was more resistant to 12Z-1 and 12Z-2,and Lizixiang and Xushu 18 were following .Shenglibaihao was more resistant to 12 Z-3 than the other varieties ,and Yan-shu 25 was following .关键词
