Abstract

Antifungal action of four benzal derivatives was examined against Puccinia striiformis, Puccinia recondita, Ustilago tritici, Alternaria brassicae and Pestalotia psiddi by spore germination inhibition method. The results have been expressed in terms of ED50 and ED90 values. Benzalmalononitrile (IIIa) was found to be the best. The efficiency of this compound against P. striiformis (ED50 40 ppm) was found to be comparable to standard fungicides.
