Ponds on your golf course may look pristine from a distance; however, on closer examination, subsurface and surface aquatic weeds may have a foothold and can take over a pond very quickly. In addition to an undesirable appearance of aquatic areas, clogged filtration systems and damaged pump stations are a few problems aquatic weeds can cause in golf course ponds. Applying an aquatic herbicide can be the most efficient use of time and budget to keep ponds clear from unwanted floating, submerged and marginal weeds.

Using a fast-acting aquatic herbicide such as Reward^® landscape and aquatic herbicide can offer targeted and powerful control of aquatic weeds. The first phytotoxic effects of Reward on above-water foliage in bright sunlight can be seen within an hour after treatment. Reward controls floating, marginal and submersed weeds including algae, cattails, hydrilla, water hyacinth, rotala, pondweeds, salvinia, watermilfoil and more.

Key features of Reward include:

• The ability to be directly applied to emerged and submerged weeds
• Its use as a spot treatment or partial area treatment for weeds, offering application flexibility
• Its tight binding to aquatic vegetation and soil sediment in water, resulting in minimal restrictions for irrigation
• The option to be used with a tank-mix partner for control of submerged weeds for a broader weed spectrum and resistance management
  • Example: using Reward with copper for filamentous algae control
