Biochemical variability among 20 Indian isolates of Sclerotinia sclerotiorum collected from different hosts/soil samples from different localities in India is reported. High Performance Liquid Chromatographic (HPLC) analysis of ethyl acetate fraction of culture filtrate, mycelia, sclerotia and sclerotial exudate showed 15~23 peaks but only 11 could be identified. They were tannic, gallic, oxalic, caffeic, vanillic, ferulic, O-coumeric, chlorogenic, cinnamic, salicylic and gentisic acids. The amount of phenolic compounds varied among the culture filtrates, mycelia, sclerotia and sclerotial exudates of S. sclerotiorum.

1-Corydalmine,an alkaloid isolated from roots of Corydalis chaerophylla inhibited spore germination of some plant pathogenic as well as saprophytic fungi e.g. Alternaria brassicae, A. brassicicola, A. solani, Curvularia lunata, C. maculans, C. sp., C. pallscens, Erysiphe pisi, Fusarium udum, Helminthosporium species,H. penniseti and a Heterosporium species. 1-Corydalmine significantly inhibited spore germination of all the fungi at 100 to 1500 ppm. It was effective against all the fungi at 1500 ppm. C. lunata was highly sensitive to this chemical even at 250 ppm.
