Phytoterpenoid isolated from Artabotrytis odoratissimus inhibited spore germination of some plant pathogenic as well as saprophytic fungi e.g. Alternaria alternata, A. solani, Cercospora sp., Curvularia maculans, C. pennisetti, Fusarium udum, Helminthosporium echinochlova, H. frumentacie, H. penniseti and Ustilago cynodontis. In Curvularia maculans and H. frumentacie, spore germination was comp...

Isolates of Cercospora species from leaves displaying symptoms of grey leaf spot were collected in maize-producing areas of south-central Brazil in 2001 and 2002. Restriction digests of the internal transcribed spacer region of rDNA detected the presence of the same two Cercospora species described on maize in the United States, namely C. zeae-maydis and the recently described species, C. zeina...

New 5-[1-(anthracen-9(10H)-ylideneamino)-2-(1H-imidazol-5-yl)ethyl]-1,3,4-thiadiazol-2-amine 3 has been synthesized from condensation reaction of N-anthracen-9(10H)-ylidenehistidine 2 with thiosemicarbazide in phosphorusoxy chloride. The prepared compounds were characterized by FTIR spectroscopy, electronic spectroscopy, NMR and NMR. Preliminary in vitro tests for fungicidal activity show that ...
