摘 要:为研究新化合物 HNPC-A113 的杀菌活性,选择水稻纹枯病、小麦白粉病和玉米锈病为防治对象,采用温室盆栽法分别研究了新化合物 HNPC-A113对它们的防治活性。结果表明:HNPC-A113 对水稻纹枯病、小麦白粉病和玉米锈病均具有很好的防治效果。HNPC-A113对水稻纹枯病的EC50 值为1.06 mg·L-1,与对照药剂噻氟酰胺EC50 值0.81 mg·L-1处于同一水平;HNPC-A113对小麦白粉病的EC50值1.21 mg·L-1,可与对照药剂氟硅唑EC50值1.27 mg·L-1相媲美;HNPC-A113 对玉米锈病的EC50值2.42 mg·L-1,稍优于对照药剂戊唑醇的EC50 值2.76 mg·L-1。HNPC-A113具有广谱杀菌活性,具有进一步研究价值。

Abstract:In order to study fungicidal activity of the new compound HNPC-A113 Rhizoctonia solani, Erysiphe graminis and Puccinia polysora were selected as control objects, efficacy of HNPC-A113 against them were studied in greenhouse. Results showed that HNPC-A113 had good control effect against Rhizoctonia solani, Erysiphe graminis and Puccinia polysora. HNPC-A113 had high fungicidal activity against Rhizoctonia solani, Erysiphe graminis and Puccinia polysora with EC50 value of 1.06 mg·L-1, 1.21 mg·L-1 and 2.42 mg·L-1, which were all comparable to that of Thifluzamide, Tluorosilicazole and Tebuconazole with EC50 value of 0.81 mg·L-1, 1.27 mg·L-1, 2.76 mg·L-1, respectively. HNPC-A113 had a broad spectrum of fungicidal activity, and it was valuable for further research and development.
