亚麻枯萎病病原菌鉴定及药剂筛选

Identification of Flax Blight Pathogeny and Medicament Selection

根据亚麻枯萎病病原菌形态特征和致病性等特点,鉴定亚麻枯萎病病原菌为Fusarium oxysporum f.sp.Lini。通过供试的13种杀菌剂对病原菌菌丝的抑制效果研究表明:对亚麻枯萎病病原菌菌丝生长有较强抑制效果的杀菌剂有枯萎灵、代森锰锌,其抑菌率均为100%,其次为多菌灵(抑菌率为86.3%),爱苗(抑菌率为83.8%),根腐宁(抑菌率为82.5%)。

According to the configuration characters of flax blight and character of pathogenicity,flax blight was examined Fusarium oxysporum f.sp.Lini.The restraining effect of thirteen germicides on mycelium showed：the effect was 100% for 30%Carbendazim·thiram WP and mancozeb,followed by carbendazim（the effect was 86.3%）,Armure 300EC（the effect was 83.8%） and Fenaminosulf（the effect was 82.5%）.
