摘 要:为了研究新化合物HNPC-A15269的杀菌活性,分别在温室和田间研究其对小麦白粉病和水稻稻瘟病的防治效果。温室盆栽实验结果表明:HNPC-A15269对小麦白粉病的防治效果(EC50 1.48 mg/L)远优于对照药剂Tebufloquin(EC50 5.22 mg/L),与对照药剂氟硅唑相当(EC50 1.51 mg/L);田间小区药效试验结果表明:HNPC-A15269在125~175 g a.i./hm2剂量下,能有效防治水稻稻瘟病,且对作物安全。新化合物HNPC-A15269具有进一步研究开发成为防治稻瘟病和白粉病等病害的杀菌剂前景。

Abstract:To research the fungicidal activity of HNPC-A15269, the fungicidal activity of HNPC-A15269 against Blumeria graminis(DC.) was tested in greenhouse trials, and the field trail of HNPC-A15269 against Pyricularia oryzae was carried out. The greenhouse trial results indicate that HNPC-A15269 had excellent activity against Blumeria graminis (DC.), EC50 value was 1.48 mg/L, better than that of Tebufloquin EC50 value 5.22 mg/L and comparable to that of Tricyclazole (EC50 1.51 mg/L). Field trial results showed that HNPC-A15269 can control Pyricularia oryzae at the dosage of 125~175 g a.i./hm2, and it was safe to the tested crops. HNPC-A15269 may be further developed as a fungicide to control Pyricularia oryzae, Blumeria graminis (DC.), etc.
Key words:HNPC-A15269; fungicidal activities; Tebufloquin; flusilazole; tricyclazole.
