Since their first registration in 1997, strobilurin fungicides have become valuable tools for managing diseases in numerous crops, including grapes and berry crops, because of their systemic nature and broad spectrum of activity against different groups of plant pathogens.


Since strobilurins have a site-specific mode of action, they are prone to fungicide resistance development in target fungi because a single mutation in a fungus can block their action.


The goal is not to manage resistance once it has developed, but rather to prevent or delay the development of fungicide resistance in the first place.
