Aquatic Carfentrazone Herbicides for Lakes and Ponds

Carfentrazone Herbicides are applied to aquatic areas for control of floating and emerged weeds such as, water hyacinth, water lettuce, and giant salvinia. Weed control is more effective on immature, actively growing weeds than on mature, less actively growing weeds. These products are a contact herbicide with little or no residual activity at recommended use rates.

Carfentrazone Herbicides provide managers with a unique and economical tool for simultaneous foliar treatment of these problem species with excellent selectivity to desirable native plants. Carfentrazone Herbicides provide fast-acting injury to susceptible floating weed species following application allowing operational field crews to visually see their treatment areas in 24 – 48 hours. Carfentrazone Herbicides can be used alone or in combination with other systemic herbicides.
