摘要
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.
