- Abstract
Field scabious (Knautia arvensis L. Coult) was chosen for study, as it was previously identified among 500 plants as potential anti-proteolytic feed additive for ruminants and reducing the number of protozoa, due to its saponin content. Saponins from aerial parts of field scabious, alfalfa and red clover as well as roots of common soapwort were tested in agar medium to study their effects on growth of two major pathogens of cereals: Gaeumannomyces graminis var. tritici (Ggt) and Fusarium culmorum (Fc). All saponins inhibited the Ggt growth. Most active saponins were from soapwort (IC50 14.1 μg/ml) followed by alfalfa (IC50 148.5 μg/ml) and red clover (IC50 156.8 μg/ml), whereas field scabious were almost inactive (IC50 >1000 μg/ml). Saponins from alfalfa, red clover and field scabious stimulated the Fc growth and only the compounds from common soapwort were slightly inhibitory to Fc growth. In most cases, the effects of saponins on growth of both fungi was dosedependent.
