What type of aquatic plants does Diquat primarily control?

Diquat is particularly effective against submersed aquatic plants. These types of weeds grow fully or partially underwater and can hinder water flow and recreational activities, as well as displace native species. Diquat functions as a contact herbicide, quickly causing the plant tissues to die upon application, which is especially useful for controlling submersed species that can be challenging to manage.

While Diquat can have effects on other types of aquatic plants, its primary use and proven efficacy lie in targeting those plants that grow beneath the water's surface. This makes it a vital tool for aquatic managers looking to address the specific issues posed by submersed weeds in aquatic environments.
