The effect of biopreparations, homogenized with the seed (seed treatment before sowing as a dressing), and used as a mixture with mineral fertilizer ANL (ammonium nitrate with limestone), upon both grain production and the health state of the winter wheat were evaluated during 2006-2009. Besides conventional soil cultivation, reduced tillage with incorporated chopped straw, and direct drilling into untilled soil covered with mulch, were also used. The following biopreparations were applied: Supresivit (Trichoderma harzianum), Polyversum (Pythium oligandrum), and Trianum P (a different strain ofTrichoderma harzianum). Attention was focused on the foliar fungi pathogens Drechslera tritici-repentis, Septoria tritici, and Alternaria triticina, as well as on the soil-borne pathogenic fungi of the genus Fusarium. 展开更多
