Shawn Malone and Michael Mayo from TPWD’s Aquatic Habitat Enhancement (AHE) crew in Brookeland sprayed giant salvinia in Chaney Branch on Lake Fork on February 17. This second chemical treatment used the contact herbicide diquat which acts to desiccate and defoliate the plants. A prior treatment in November 2015 used glyphosate, a broad-spectrum systemic herbicide and Galleon, an acetolactate synthase inhibitor. TPWD is continuing an aggressive plan to prevent the spread of giant salvinia to new areas on the lake and to treat existing plants in Chaney Branch. The effectiveness of yesterday’s treatment will be evaluated in 3 weeks time.
Boaters are reminded to adhere to TPWD’s “Clean, drain, and dry” campaign to prevent the spread of aquatic invasive species (AIS) into Texas lakes.
