A series of novel N-(2-(phenylamino)-4-fluorophenyl)-pyrazole-4-carboxamides 1–15 and aromatic carboxamides with a diphenylamine scaffold 16–29 were designed, synthesized, and evaluated for their antifungal activities. In vitro experiments showed that compound 6 (EC50 = 0.03 mg/L) was superior to bixafen (EC50 = 0.04 mg/L) against Rhizoctoinia solani and compound 6 (IC50 = 1.41 mg/L) was close to bixafen

EC 50 = 0.03 mg / L)优于bisxafen(
EC 50 = 0.04 mg / L)对抗茄枯萎病,化合物6(IC 50 = 1.41 mg / L)与bixafen(IC 50)接近50 = 1.22 mg / L)对茄红细菌的
琥珀酸脱氢酶。另外,体内盆栽实验表明,化合物6(
EC 50 = 1.93 mg / L)比比沙芬(
EC 50 = 3.72 mg / L)更好,并且对
噻菌胺接近
噻吩甲酰胺(
EC 50 = 1.83 mg / L)。体内实地试验表明,化合物6在200克活性成分公顷-1有后21天具有两个喷洒对
