Abstract
3-(2-Pyridyl)-3-iminoisatin, 1-piperidinomethyl-3-(2-pyridyl)-3-iminoisatin, and 1-acetyl-3-(2-pyridyl)-3-iminoisatin affect spore germination ofAlternaria alternata, A. carthemi, Curvularia lunata, Fusarium oxysporum f.sp.cieri andF. udum and influence the development of powdery mildew (Erysiphe pisi) on pea under glasshouse condition as well as conidial germination ofE. pisi on excised pea leaves. Spore germination was inhibited in the sequence 1-acetyl-3-(2-pyridyl)-3-iminoisatin > 1-piperidinomethyl-3-(2-pyridyl)-3-iminoisatin > 3-(2-pyridyl)-3-iminoisatin followed the order accordingly. The powdery mildew development and conidial germination ofE. pisi 1-piperidinomethyl-3-(2-pyridyl)-3-iminoisatin > 1-acetyl-3-(2-pyridyl)-3-iminoisatin > 3-(2-pyridyl)-3-iminoisatin. The chemicals were compared with commonly used antifungal fungicides.
