采用菌丝生长速率法测定了13种杀菌剂对玉米穗腐病菌（ Fusarium graminearum）的室内毒力。试验结果表明：多菌灵、氟硅唑、氟菌唑、丙环唑、代森锰锌和烯唑醇6种杀菌剂对穗腐病菌抑菌效果较好，其EC50值分别为0?11，0?22，0?26，0?88，1?09，2?99μg／mL。对多菌灵、氟硅唑、丙环唑和代森锰锌4种药剂进一步进行了田间药效试验，有效成分用量丙环唑150?00 g／hm2、氟硅唑51?00 g／hm2在发病初期穗部喷施对玉米穗腐病的田间防治效果分别达66?14％和66?04％。产量测定结果表明：丙环唑用量为150?00 g／hm2处理的小区产量最高，增产效果显著，其次是氟硅唑用量为51?00 g／hm2。

Indoor toxicity of thirteen fungicides against Fusarium graminearum was tested by myceli?um growth rate method. The results showed that the toxicity of carbendazim, flusilazole, triflumizole, propiconazole, mancozeb and diniconazole to the pathogen was stronger than that of others,and EC50 value was 0.11, 0.22, 0.26, 0.88, 1.09 and 2.99μg/mL, respectively. Field efficiency trials of four fungicides, carbendazim, flusilazole, propiconazole and mancozeb, indicated that propiconazole and flusilazole had relatively high control efficiency on maize ear rot, 66.14% and 66.04% respec?tively in field at active ingredient dosage of 150.00 g/hm2 and 51.00 g/hm2 . The results of yield de?termination showed that the plot treated by propiconazole at active ingredient dosage of 150.00 g/hm2 had the highest yield,followed by flusilazole at dosage of 51.00 g/hm2
