摘　　要：车前草穂枯病是江西吉安车前草产区一种毁灭性真菌病害。本文采用菌丝生长速率法测定了火把、凯润、爱普、温立停和甲基托布津5种杀菌剂对车前草穗枯病菌(Fusicoccum sp.)的毒力,各药剂的EC50值依次为:1.2514、8.7601、20.9266、196.7915和4887.4862μg/mL。田间试验结果表明:火把对车前草穗枯病的防效最好,达94.92%,凯润和爱普也有较好的防效,分别为84.96%和82.11%,而温立停和甲基托布津的防效较差,分别只有64.02%和41.87%。Plantain head blight is a devastating disease in Ji＇an city of Jiangxi province. The laboratory toxicities of Thiram zirarn, CabrioTM, Aipu, Wenliting and Thiophanate methyl against Fusicoccum sp. were tested by using mycelial growth rate method, and the ECs0 values of these fungicides were 1.2514, 8.7601, 20.9266, 196.7915 and 4887.4862μg/ml, respectively. The field trials further revealed that Thiram ziram, CabrioTM and Aipu had good control effects of 94.92%, 84.96%, and 82.11%, while the control effects of Werditing and Thiophanate methyl only stayed at 64.02%and 41.87%, respectively.
