Document Description
The primary treatment method for the SCP will be aquatic herbicides. DBW is seeking approval for the use of five different herbicides for the SCP. Approval of five herbicides will provide flexibility in targeting this new invasive species and allow DBW to identify herbicides that will effectively treat the plant while minimizing the potential for negative environmental effects. All of the five herbicide active ingredients have been approved for the WHCP and/or EDCP: 2,4-D, glyphosate, imazamox, penoxsulam, and diquat. All five herbicides have been proven effective in treatment spongeplant, or the closely related species, American frogbit (Limnobium spongia). All herbicides will be used with an adjuvant surfactant, Agridex or Competitor, to increase adhesion to spongeplant leaves. When appropriate, DBW will also utilize a water conditioning agent to improve herbicide effectiveness, and a spray pattern indicator to identify treated plants.
