Connecticut Battles Invasive Hydrilla with Diquat Herbicide

The Connecticut Department of Energy and Environmental Protection (DEEP) has announced plans to use the herbicide diquat to control the spread of hydrilla, an invasive aquatic plant that has been found in several lakes and waterways throughout the state. Hydrilla is a highly invasive species that can outcompete native plants and harm the ecosystem. It was first discovered in Connecticut in 2016 and has since been found in several lakes, including Lake Pocotopaug and Lake Zoar. The DEEP has been working to control the spread of hydrilla through manual removal and other methods, but the use of diquat is a new approach. Diquat is a fast-acting herbicide that can be effective in controlling hydrilla, but it can also harm other aquatic plants and animals. The DEEP has developed a plan to minimize the impact of diquat on the environment and to ensure that it is used safely and effectively. The plan includes conducting thorough environmental assessments and monitoring the effects of the herbicide on the ecosystem. The DEEP will also be working with local communities and stakeholders to educate them about the risks and benefits of using diquat to control hydrilla. In addition to using diquat, the DEEP will also be continuing to manually remove hydrilla from affected lakes and waterways. The agency will also be working to prevent the spread of hydrilla by educating boaters and other users of the lakes and waterways about the risks of transporting the plant to new locations. The use of diquat to control hydrilla is a controversial issue, with some environmental groups expressing concerns about the potential impact on the ecosystem. However, the DEEP believes that the use of diquat is necessary to control the spread of hydrilla and to protect the state’s aquatic ecosystems. The DEEP will be monitoring the effects of diquat closely and will make adjustments to the plan as needed. The agency will also be working to develop long-term strategies for controlling hydrilla and preventing its spread. This may include the use of other herbicides or methods, such as biological control. The DEEP is also working with other states and federal agencies to share information and best practices for controlling hydrilla. The use of diquat to control hydrilla is just one part of a larger effort to protect Connecticut’s aquatic ecosystems from invasive species. The DEEP is also working to control other invasive species, such as zebra mussels and Eurasian watermilfoil. The agency is also working to educate the public about the risks of invasive species and to prevent their spread. Overall, the use of diquat to control hydrilla is a complex issue that requires careful consideration of the potential risks and benefits. The DEEP is working to ensure that the herbicide is used safely and effectively, while also minimizing its impact on the environment.
