Trichoderma viride Pers. against pathogenic microorganisms of Dianthus L

Micromycete Trichoderma viride Pers. strain 113 was selected and used against microorganisms causing pink roots rot Alternaria alternata, Fussarium oxysporum, F. solani, Mortierella isabelina and Verticillium albo atrum. The micromycetes-antagonists inhibited development of those fungi under laboratory conditions. When the antagonist was used for infection with these micromycetes, the negative effect on pink seedlings decreased but did not disappear completely. It became clear that not all the pathogenic fungi were susceptible to Trichoderma viride at the same extent. It was revealed that the positive effect of the antagonist was decreased by Aspergillus fumigatus Fresen., spread widely in substrataBotanikos institutasVytauto Didžiojo universiteta
