Abstrakt: The survival and growth of plant pathogens on crop residues are key factors facilitating the dynamics of crop diseases. Spores (e.g., perithecia, and chlamydospores) and mycelium of pathogenic fungi overwinter on harvest residues, such as straw, and serve as initial inoculum infecting crops in the next growing season. Therefore, targeting overwintering fungi is essential to attaining effective disease control. Beneficial microorganisms offer advantages in controlling pathogens through their ability to colonize and exploit different environmental niches. In this study, we applied qPCR assays to explore the biocontrol performance of locally isolated strains of Clonostachys against various Fusarium pathogens. We proved that prior colonization of wheat straw by Fusarium spp. can be effectively reduced by Clonostachys rosea. We demonstrated that the efficiency of C. rosea to reduce Fusarium inoculum appears to remain at a similar level for most studied strains regardless of the target pathogen and the level of colonization of substrates by pathogens. Efficient performance of local C. rosea strains identifies possible targets for future strategies to control Fusarium diseases in cereals. Our study also highlights the challenge in sequence-based determination of C. rosea, which is crucial for the efficient selection of beneficial strains for biocontrol purposes.
