Trichodermo spp. as a seed dressing bioproduct against damping-off seedlings of vegetables crops

摘要

The aim of study was to assess the effect of carrot seed dressing with selected isolates of the fungus Trichoderma spp. against damping-off seedlings of carrots. It was shown that the used isolates of Trichoderma spp. significantly reduced the infection of germinating seeds and carrots seedlings by the pathogenic fungus species Pythium spp. The use of Trichoderma spp. more efficiently affected the height and weight of the tested carrot seedlings as compared to thestandart seed dressing Zaprawa Nasienna T 75 DS/WS, as well as the biopreparation based on Trichoderma harzianum. No effect of phytotoxicity of Trichoderma spp. isolates used on seed germination and the development of carrot seedlings was started.
