The extract of garden angelica (Archangelica officinalis Hoffm. ) fruit which contained furanocoumarine compounds dissolved in dimethyl sulfoxide (DMSO) was used. The effect of the furanocoumarine preparation on the growth of mycelium, sporulation and sclerotia formation of Helminthosporium allii K 67, Penicillium viridicatum C 721, Fusarium oxysporum f. sp. cepae C 546, F. oxysporum f. sp. phaseoli F 7, Fusarium culmorum 100, Rhizoctonia solani S 101, S 3, Phoma exigua S 138, Sclerotinia sclerotiorum S 65, Botrytis cinerea S 40, Ascochyta pisi 29, Monilia coryli L 657 and Phomopsis viticola 2305 was determined. The experiment comprised three treatments, including concentrations of 10, 100 and 1000 ppm of the furanocoumarine preparation as well as four controls: K0 - malt agar only, K1, K2, K3 - the medium containing 10, 100 and 1000 ppm of pure DMSO respectively. The growth of fungi studied on the agar medium with an addition of furanocoumarine preparation was differentiated independently of its concentration. In the experimental treatment with the preparation tested at 10 ppm dose, a slight inhibitory effect (3.9-11.8%) on the fungi was observed. At the concentration of 100 ppm, growth inhibition was considerably greater and it ranged from 13.5 to 56.9%, while at the concentration of 1000 ppm it was between 84 and 100%. The inhibitory effect of pure DMSO at the concentration of 1000 ppm (K3) on the examined fungi was shown. DMSO solvent at lower concentrations, i.e. 10 and 100 ppm caused a slight inhibition of the mycelium growth.
