Resumen
[EN]Botrytis cinerea is a phytopathogenic fungus responsible for economic losses from USD 10
to 100 billion worldwide. It affects more than 1400 plant species, thus becoming one of the main
threats to the agriculture systems. The application of fungicides has for years been an efficient way
to control this disease. However, fungicides have negative environmental consequences that have
changed popular opinion and clarified the need for more sustainable solutions. Biopesticides are
products formulated based on microorganisms (bacteria or fungi) with antifungal activity through
various mechanisms. This review gathers the most important mechanisms of antifungal activities
and the microorganisms that possess them. Among the different modes of action, there are included
the production of diffusible molecules, both antimicrobial molecules and siderophores; production of
volatile organic compounds; production of hydrolytic enzymes; and other mechanisms, such as the
competition and induction of systemic resistance, triggering an interaction at different levels and
inhibition based on complex systems for the production of molecules and regulation of crop biology.
Such a variety of mechanisms results in a powerful weapon against B. cinerea; some of them have
been tested and are already used in the agricultural production with satisfactory results.
