摘　　要：车前草穂枯病是江西吉安车前草产区发生最严重的一种真菌病害。本文采用菌丝生长速率法测定了6种杀菌剂对车前草穂枯病菌的毒力,结果表明菌毒神丹的毒力最强,EC50值为3.2921μg/mL;多菌灵的毒力最弱,EC50值为8 316.0393μg/mL;其他4种药剂已蒜素、奥普安、代森锰锌和菌毒克的毒力介于其间,EC50值依次为7.8253μg/mL,32.9139μg/mL、140.7006μg/mL和400.4089μl/mL。Plantain head blight is the most important disease in plantain-growing area of Ji＇an city in Jiangxi province. Toxicities of six fungicides against Fusicoccum sp. were investigated in laboratory with the method of mycelium growth rate. The results showed that Jundushendan had the best inhibiting effect to Fusicoccum sp. with EC50 value of 3.2921 μg/mL; Duojunling had the worst inhibiting effect with EC50 value of 8 316.0393μg/mL. EC50 values for Yisuansu, A-PRO-80, Mancozeb and Junduke were 7.8253μg/mL, 32.9139μg/mL, 140.7006μg/mL and 400.4089μl/mL, respectively,
