| Abstract: | A plant quaternary alkaloid Δ3-alstovenine inhibited the spore germination of most of the fungi tested at concentration of 250–1000 mg/L. Saprophytic and
biotrophic fungi were equally sensitive to the alkaloid.Cercospora sp. was the most sensitive as 100% inhibition of spore germination was observed at 250 mg/L.Alternaria species,Curvularia species andFusarium udum were not affected even at 1000 mg/L. |
