Abstract

Fungal plant pathogens are the primary factors responsible for significant losses to agricultural products annually. The predominant method of controlling fungal diseases has been the use of fungicides; however, there is a global shift towards reducing their application. Biocontrol agents offer a viable alternative to chemical control for the eradication of fungal diseases. Throughout their life cycle, plants interact with diverse pathogens that impact their health through various mechanisms. Fungal biocontrol agents employ multiple modes of action, including antibiosis, competition for nutrients and space, and mycoparasitism, with the specific mechanism varying according to the pathogen-host combination. While competition for space and nutrients is the primary mode of action for fungi, bacteria often produce antibiotics. These mechanisms may act consecutively, making it challenging to identify the association with specific antifungal actions. This summary provides an overview of the modes of action of fungal antagonists.
