Matt works for a golf course in Charlotte, NC. He went out early one morning to check on their ponds and saw some aquatic plants sticking out on the edge of the water. He had never seen it before, so he called the Clemson Extension office. They determined it was alligator weed; an emergent aquatic weed.
He was embarrassed his customers would see the aquatic weeds and think they didn’t properly care for their ponds. He went to the store and tried multiple products, but none seemed to keep it away. Finally, he called Platinum Ponds and Lake Management to see if we could help. We told him about becoming a member to assure their ponds are always healthy and beautiful.
Matt was so relieved to know he would have healthy and beautiful ponds on his golf courses so he wouldn’t have to be embarrassed anymore. He became a member so he wouldn’t have to worry about the embarrassment that comes with ugly aquatic weeds.
We knew Aquasweep herbicide would be best for Matt’s golf course ponds. It’s the first liquid premix with full terrestrial and aquatic uses. AquaSweep is the perfect base for any selective weed control program distributed within aquatic and wetland areas. You see quick and long lasting results.
Aquasweep herbicide controls emergent, floating and submerged aquatic weeds and also offers exceptional control of invasive and noxious weeds and brush on roadsides, right-of-ways, ditchbanks, aquatic sites, pastures and along fence rows.

****Liquid vs. Granular Aquatic Herbicides: Which Is Right for Your Pond?**
Choosing the right herbicide form can make all the difference when dealing with stubborn aquatic weeds. So, what’s the real difference between liquid and granular aquatic herbicides?
Liquid Herbicides
Liquid herbicides are typically mixed with water and applied as a spray, directly targeting unwanted aquatic plants—whether they’re floating on the surface or lurking just below. When combined with a surfactant (think of it like herbicide superglue), liquids stick to leaves and stems more effectively, allowing for fast absorption. This usually means you see results in short order—ideal when you need quick action to impress golfers or picnic-goers!
Granular Herbicides
Granular herbicides, on the other hand, come as small pellets or granules that you broadcast across the water or directly onto weed patches. These slowly release active ingredients as they sink, targeting plants at or near the bottom and along the shoreline. Granules are especially handy in areas with moving water, since they’re less likely to wash away before doing their job. They may act a bit more gradually, but the tradeoff is often longer-lasting results after a single application.
Which Should You Use?
Use liquids if you need a fast, visible improvement and want to treat floating or submerged weeds. Opt for granules when shoreline or bottom-rooted weeds are your main concern, or when water movement is likely to dilute a spray.
Many pond managers use a combination, targeting multiple problem areas with the right tool for each job.
No matter which type you choose, matching the herbicide to your pond’s needs—and ensuring you get the right weeds—will help keep embarrassment at bay and your water looking beautiful year-round.
Liquid vs. Granular Aquatic Herbicides: Pros and Cons
When it comes to tackling stubborn aquatic weeds, choosing the right herbicide formulation makes all the difference. Both liquid and granular herbicides are effective in pond and lake management, but each comes with its own set of advantages (and a few trade-offs).
Liquid Aquatic Herbicides
Liquid herbicides, like the kind Matt first tried, are typically diluted with water and often paired with a surfactant to help the product stick to plant surfaces. They excel in these scenarios:
Fast-Acting Results: Liquids are quickly absorbed by submerged and floating weeds, so you usually see visible results sooner.
Direct Application Precision: Spraying lets you target specific areas and individual plants—ideal for spot treatments or dealing with surface weeds. Ease of Use: Mixing and application is straightforward, especially when treating smaller or isolated infestations.
However, liquids may require more frequent applications, particularly in areas with heavy water movement that can dilute the product. If you have a large area or recurring weed problems, those repeat treatments can add up.
****Granular Aquatic Herbicides****
Granular weed killers come in pellet or granule form, and are simply broadcast over the water or placed near problem spots.
Long-Lasting Control: Because the granules dissolve slowly, they provide ongoing treatment—great for season-long prevention.
Best for Shorelines and Emergent Weeds: Granular products sink to the bottom, targeting roots and stubborn weeds that live at the water’s edge and preventing new growth before it starts.
Effective in Flowing Water: Granules are less prone to being swept away, making them a smart choice for ponds or channels with moving water.
On the downside, granular options can take longer to deliver visible results—so if you want quick aesthetic improvement, you’ll need a little patience. And, while they cover large areas well, broadcast application doesn’t allow for the same pinpoint accuracy as a spray.
