Cinnamalaniline and its N-phenyl derivatives (I-VII) were examined in vitro for their antifungal potential against Alternaria alternata, Fusarium oxysporum, Colletotrichum capsici, Myrothecium roridum and Ustilago tritici by spore germination inhibition method and against Phytophthora infestans by detached leaf technique. Cinnamal-4-fluoroaniline (V) recorded disease intensity of 9.0 per cent at 2000 ppm, better than that of Indofil M-45 and comparable with Ridomil-MZ. The compounds I-VII were also tested for their nematicidal activity against Ditylenchus myceliophagus using poison food technique and aqueous in vitro screening method. Compounds II and V showed 100 per cent mortality and almost complete control of nematode population build up at 1000 ppm.
