Why Choose a water-dispersible granule?

  • Quick contact action: A strong fit when you want fast knockdown instead of a slower program.
  • Flexible placement: Surface and subsurface directions make it easier to match the weed problem in front of you.
  • Smarter quantity planning: Published ppb and per-acre rates help size 1 lb or 5 lb purchases with less guesswork.

What is Propeller Aquatic Herbicide best used for?
Propeller Aquatic Herbicide is best used for fast contact control of listed floating, emergent, and submerged weeds in slow-moving or quiescent waters. It is a strong fit when you want one flumioxazin WDG that can work as a surface spray or a subsurface treatment instead of limiting yourself to only one approach. That makes it especially useful for ponds, canals, reservoirs, and similar sites where weed pressure can vary from the surface down into the water column.
Does Propeller work on duckweed, watermeal, hydrilla, or milfoil?
Yes. Propeller is a strong fit for several of the weeds buyers ask about most often, including duckweed, watermeal, hydrilla, Eurasian watermilfoil, variable-leaf watermilfoil, water lettuce, salvinia, and selected pondweeds. It is especially appealing when you want one product that can cover floating mats and certain submerged growth, which simplifies planning for mixed infestations.
Should I buy the 1 lb or 5 lb container?
Buy the 1 lb size when you are treating smaller areas, handling spot work, or want a lower entry point for precise treatments. The 5 lb size is the better value when you have broader acreage, repeated seasonal work, or need enough product for deeper-water subsurface rates. Because Propeller rates change by surface acre, water depth, and ppb target, the right size is really a quantity-planning decision, not just a price decision.
How much Propeller do I need for my pond?
The answer depends on whether you are treating surface weeds or building a subsurface concentration in the water column. Surface applications run 6 to 12 ounces per surface acre, while subsurface applications are calculated to reach 200 to 400 ppb and increase with water depth, so a shallow cove and a deeper pond can require very different amounts. That label structure is useful because it lets you size the order around real treatment conditions instead of guessing. Q: How do you apply Propeller for the best results?
How do you apply Propeller for the best results?
For floating and emerged weeds, Propeller is applied as a broadcast spray to actively growing foliage with an aquatic-approved adjuvant and enough water for full coverage. For submerged weeds, it is used as a subsurface treatment and works best with good placement in the plant stand, early morning timing, and early-season applications before heavy surface matting develops. In both cases, younger actively growing weeds give you the best chance at a clean, efficient treatment.
How fast does Propeller work?
Propeller is chosen for fast contact activity, so it is used when buyers want a quicker response than a slower systemic program. Exact timing depends on coverage, weed stage, pH, and treatment conditions, but this chemistry is designed for active knockdown rather than a slow season-long response. For longer-term pond improvement, many managers pair chemical knockdown with beneficial microbes so dead biomass and excess organics break down more efficiently instead of feeding the next cycle of growth.
Can I swim, fish, or use treated water after application?
Treated water has no post-application holding restriction for drinking or recreational uses such as swimming and fishing. The bigger planning issue is irrigation: food-crop irrigation requires a five-day wait, and ornamental irrigation timing depends on application method, water depth, or ppb concentration. That distinction helps buyers avoid over-restricting normal pond use while still planning responsibly for irrigation.
When is Propeller a better choice than a slower systemic herbicide?
Propeller is a better fit when fast contact control matters, when you have mixed floating and submerged pressure, or when you want the flexibility to choose surface or subsurface delivery. A slower systemic program can make sense when longer whole-plant movement is the priority and a slower response is acceptable. Propeller is often the more practical choice for fast intervention and precise seasonal management.
What conditions can reduce performance?
High water pH, especially above 8.5 around dense submerged vegetation later in the day, can reduce control and increase the chance of regrowth. Propeller also works best when weeds are young and actively growing, with solid coverage for surface work and good placement for subsurface treatments. Dense vegetation should be treated in sections so you can manage oxygen loss risk more carefully.

I tried cheeaper brands that did not thing. this one works.

Edgar Ayes, OH
Excellent customer service

Verified Purchase

I use with surfactant works better. Great comapny and great stuff.

Jules, TN
Works great!

Verified Purchase

So far so good! We have a 4 acre lake that serves our historic village park, and it was covered with watermeal and duckweed. We treated it in quarters to avoid killing too much too fast and the product worked great. The water is much cleaner now and we are adding the microbes and just a little blue dye for aesthetics. Hopefully nothing will appear next year!

Ken Harper, IL
Kills everything

Verified Purchase

I work for the public works department and we use this on drainage ditches, wastewater lagoons, data center cooling ponds and the list goes on. It kills practically all milfoil, duck weed, coontail, floating algae and underwater. Our go-to product for just about everything.

Jess R, NM
Better than grass carp

Verified Purchase

I tried 6 grass carp 2 years ago. Last year, only 1 carp left (no idea where the other went) and it barely puts a dent in the watermeal. Applied this by sprayer along shoreline day 1, then half treatments 7 days apart. Pond is watermeal free and carp does not seem to mind.

Maintenance has been battling watermeal in 3 aquatic features at our busy botanical garden, and finally, we found something that worked fast. Recommend.

dollar bonnet

Our Pond was 95% covered with dollar bonnet. Sprayed late in the afternoon and most looked sick the next day. 1 week later we are at 10% coverage this product works well.
