New Systemic Herbicide for Large-Scale Aquatic Plant Management
Galleon SC represents an exciting new technology for management of a variety of submersed, floating, and emergent invasive and nuisance aquatic plants.
What is Galleon SC?
Galleon SC is the first acetolactate synthase inhibitor (ALS) fully registered by U.S. EPA for submersed weed control. Galleon SC is classified as an EPA Reduced-Risk Aquatic Herbicide based on its use characteristics and toxicology. Galleon SC provides a much-needed, additional systemic mode of action for hydrilla control in integrated control programs designed for improved herbicide resistance management.
- Key target aquatic weed species: hydrilla, water hyacinth, water lettuce, salvinia species, frog’s bit and duckweed.
- Multiple forms of application give flexibility to choose best management option:
- Injection for large-scale, in-water treatment of submersed and floating species
- Foliar sprays via ground, boat, or aerial application for targeted treatments of floating and emergent species
- Direct application to exposed littoral sediment for pre-emergence control following drawdown or other low-water events.
- In-water treatments of hydrilla with Galleon SC at sustained doses of 5 - 20 ppb will produce one to two seasons of control under most conditions along with simultaneous action on most floating weeds with greatly extended control (two plus seasons) versus traditional spray methods.
- Low foliar use rates typically between 2 - 4 oz per acre for floating and emergent weed control reduce applicator exposure and improve logistics versus current herbicide options.
- Similar to Sonar*, gradual death of treated target weeds allows large infestations to be treated effectively while maintaining overall water quality.
- Good safety on perennial aquatic grasses such as maidencane and knotgrass, and many other desirable native plants including coontail, lotus and waterlily.
- No restrictions on use of treated water for drinking, swimming or fishing. Food crop irrigation requires less than 1 ppb in treated water. Minimal restrictions on turf irrigation. Consult with SePRO on latest recommendations for non-food crop irrigation.
- Excellent rotational complement to Sonar in Integrated Pest Management (IPM) programs for herbicide resistance management.
- FasTEST* assays are available for quantitative, cost-effective monitoring of Galleon SC treatments to maximize performance and meet product label requirements.
- For best long-term environmental stewardship of Galleon SC, applicator training will be required in Best Management Practices (BMP) for product assessment, prescription and implementation.
