STRAINS Cryptococcus flavescens RESISTANT TO ANTIOCONAZOLE FOR BIOLOGICAL CONTROL OF FUSARIOSIS

摘要

1. A microorganism comprising a Cryptococcus flavescens strain resistant to prothioconazole and selected from the group consisting of Cryptococcus flavescens 3C (NRRL Y-50378) and Cryptococcus flavescens 4C (NRRL Y-50379). 2. The microorganism according to claim 1, characterized in that it is a largely biologically pure culture. The microorganism according to claim 1, characterized in that said strain is Cryptococcus flavescens 3C (NRRL Y-50378). The microorganism according to claim 1, characterized in that said strain is Cryptococcus flavescens 4C (NRRL Y-50379). A method for suppressing cereal fusarium, comprising introducing at least one antagonist microorganism selected from the group consisting of the Cryptococcus flavescens 3C strain (NRRL Y-50378) and the Cryptococcus flavescens 4C strain (NRRL Y-50379) and combinations thereof into the ear of said cereal; moreover, the specified antagonist microorganism is introduced in an amount effective to reduce the level of fusariosis in comparison with the same level observed for untreated control. The method according to claim 5, characterized in that said antagonist microorganism is a substantially biologically pure culture. The method according to claim 5, characterized in that said antagonist microorganism is Cryptococcus flavescens 3C (NRRL Y-50378). The method according to claim 5, characterized in that said antagonist microorganism is Cryptococcus flavescens 4C (NRRL Y-50379). The method according to claim 5, characterized in that said antagonist microorganism is introduced into the ear before the onset of the phase of solid ripeness. The method according to claim 5, characterized in that said antagonist microorganism is introduced into the ear during flowering. The method according to claim 5, characterized in that said antagonist microorganism is introduced into the ear before flowering. Way
