Which aquatic weed species in Florida has documented herbicide-resistant populations?

The presence of documented herbicide-resistant populations in aquatic weed species is particularly relevant in the context of managing invasive plant growth in Florida. Hydrilla, specifically, has been shown to develop resistance to certain herbicides over time, which makes it a significant concern for aquatic management. Understanding the adaptive nature of these weeds is crucial for effective control strategies.

Dotted duckweed, while common in aquatic systems, does not have the same level of documented herbicide resistance as hydrilla. The adaptation of hydrilla to various herbicides signifies a need for increased vigilance and the necessity to explore alternative management practices. By recognizing which species have developed resistance, aquatic managers can better tailor their control methods to combat these resilient populations effectively.
