In declining broadleaf forests in western Ukraine, several Phytophthora species including P. plurivora, bilorbang, polonica, gonapodyides and cactorum were recovered using soil baiting assays identified morphological molecular methods. Pathogenicity tests of selected isolates performed on black alder (Alnus glutinosa (L.) Gaerth.) silver birch (Betula pendula Roth.) to assess susceptibility the...

GOTTLIEB, D., R. J. KNAUS, and S. G. WOOD. 1978. Differences in the Sterol synthesizing pathways of sterol-producing and non-sterol-producing fungi. Phytopathology 68: I 168-1169. The mycelia of several sterol-producing and non-sterolsqualene was detected in the non-sterol-producing fungi. The producing fungi were analyzed for the presence of squalene, block in the synthesis of ergosterol by th...

The antagonistic activity of three bacterial isolates namely Microbacterium terregens, Cellulosimicrobium cellulans and Bacillus amylollquefaciens was evaluated through direct confrontation method and filtrates culture against the growth of Fusarium solani, Fusarium oxysporum, Rhizoctonia solani and Phytophthra cactorum. All bacterial isolates showed the inhibition of the mycelia growth of the ...

Antimicrobial screening against selected Gram-positive and Gram-negative bacteria, yeasts, mold, as well as plant pathogenic fungi, with emphasis on method optimization was carried out on methanol extracts prepared from seven plants grown in Finland. Sensitivity to the extracts was found to vary considerably among the micro-organisms, the extract from Petroselinum crispum and Ruta graveolens sh...
