水稻稻瘟病和纹枯病是水稻上重要的真菌性病害,化学防治是其主要防控措施之一,本研究旨在通过室内毒力测定筛选对稻瘟病菌和水稻纹枯病菌毒力作用强的杀菌剂。采用菌丝生长速率法测定了7种杀菌剂制剂对水稻稻瘟病菌和纹枯病菌的室内毒力作用。测定结果表明,在3种琥珀酸脱氢酶抑制剂（SDHI）类杀菌剂制剂中,6.25%Fluindapyr（研发代号IR9792）EC对稻瘟病菌毒力作用最强,EC50为1.01 mg/L;在3种甲氧基丙烯酸酯（Strobilurin）类的杀菌剂制剂中25%吡唑醚菌酯EC对稻瘟病菌毒力最高,EC50为0.01 mg/L;***硫酮类杀菌剂48%丙硫菌唑SC对稻瘟病菌的EC50为0.70 mg/L。对于纹枯病菌,琥珀酸脱氢酶抑制剂（SDH...

Rice blast and sheath blight are very important fungal diseases in rice, and one of the mainmeasures to control these diseases is chemical control. The paper aims to select the fungicides with strongtoxicity against Magnaporthe oryzae and Rhizoctonia solani by indoor toxicity determination. The toxicity of 7 fungicides against M. oryzae and R. solani was determined by the mycelial growth rate method in the laboratory. Theresults showed that： 6.25% Fluindapyr（codenamed IR9792） EC had the strongest toxicity with EC501.01 mg/L,against M. oryzae...
