INFLUENCE OF TR1CHODERMA STRAINS ON THE GROWTH OF PATHOGENIC MOULDS IN BIOTIC TEST ON UNTYPICAL CARBON SOURCES

Abstract. In the present paper the research was focused on mutual interaction between three strains of Trichoderma and nine phytopathogenic moulds. Dual biotic test was madę in media imitating natural emironmental conditions (milled grain of four typical cereals), which was a modification of a standard procedurę. Eveiy tested and test-strain exploited cereals as the source of nutritive compounds to a different extent. which was exhibiled by various growth speed and changes in interactions. The highest antagonistic ability was dem-onstrated for Trichoderma harziamum T33, which in many cases caused complete grow th inhibilion of tested moulds. Neither of the phytopathogenic strains had a negath e influence on the T33 strain, in contrast to the rest of Trichoderma strains
