What was the first confirmed incidence of herbicide resistance in Florida?

The first confirmed incidence of herbicide resistance in Florida is linked to the broadleaf weed American black nightshade in 1985. This event is significant in the context of herbicide use, as it marked the beginning of a growing challenge for agricultural and aquatic weed management professionals in the state.

American black nightshade's resistance to herbicides called attention to the need for integrated weed management strategies that encompassed not only chemical options but also cultural and mechanical practices. The emergence of resistance highlighted the importance of rotating herbicide modes of action and utilizing different management techniques to mitigate further development of resistance in other weed species.

Understanding this historical context helps inform current practices in weed management, emphasizing proactive measures to prevent future occurrences of herbicide resistance in various aquatic and terrestrial ecosystems.
