  3. 2. Evaluation of in vitro antagonism assays in the mycoparasitic fungus Clonostachys rosea

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Victor Olsson; [2020]
    Keywords : Biocontrol; Biocontrol agent; Clonostachys rosea; Fusarium gramine-arum;

    Abstract : Fungicide use is the dominant direct method to control fungal pathogens on crops in agriculture. While effective, excessive use of them can be harmful to biodiversity and lead to fungicide resistance in pathogen populations. Biocontrol is an alternative where natural antagonistic organisms, called biocontrol agents (BCA), are used to protect crops. READ MORE
