I’ve heard a lot about Clipper Herbicide. What does it do? | Ponds & Lakes Q&A

Q: I’ve heard a lot about Clipper Herbicide. What does it do?

Eldon – Urbandale, IA

A: Clipper™ Aquatic Herbicide controls a wide variety of algae, floating weeds and submerged weeds, but its claim to fame is its ability to wipe out troublesome watermeal and duckweed—two aquatic weeds that can be difficult to manage in any pond or lake. In fact, when used as directed, up to 80 percent of duckweed and watermeal will be eliminated within the first application of Clipper™. Not too shabby!

Here are some tips for use:

  • Check your pH first: High pH levels will reduce Clipper’s™ effectiveness, so test the pH of your pond’s water with a pH Test Kit before using the herbicide. Apply it only when the pH is 8.5 and below.
  • Apply on a sunny morning: The herbicide is a reactive treatment that works better in the sunlight, so treat your pond or lake early in the morning on a sunny day. Hold off on adding light-blocking Pond Dye to your water, until after Clipper™ has had a chance to go to work on the weeds.
  • Spray and play: Applying Clipper™ to aquatic weeds is easy. Simply mix the amount of Clipper™ and water in a Specialty Pond Sprayer according to label instructions, and spray onto floating weeds and algae or place the tip beneath the water’s surface to treat submerged weeds. Over time, the weeds will begin to brown and die.
  • A little goes a long way: You only need to use 1 pound of Clipper™ per surface acre one to two times per year. Because it’s a contact herbicide, complete coverage is essential for effective control. You can reapply Clipper™ after 28 days if you find that you’ve missed some weed patches after the first treatment.
  • No temperature restrictions: Clipper™ can be used year-round in any temperature, but it should be applied only when the weeds are actively growing.
  • Rake away the debris: Once the aquatic weeds are completely dead, use a rake—like the Pond & Beach Rake —to remove the debris. This will prevent the foliage from accumulating and turning into algae-feeding muck.

Clipper™ Aquatic Herbicide can be used in a range of waterways, including bayous, canals, drainage ditches, lakes, marshes, freshwater ponds and reservoirs. It quickly and effectively controls watermeal, duckweed, water lettuce, giant salvinia, cabomba, Eurasian watermilfoil, hydrilla and curlyleaf pondweed. If you fight aquatic weeds in your lake or pond, consider using Clipper™. It’s good stuff!

How Do I Treat Duckweed? | Ponds & Lakes Q&A

How Do I Treat Duckweed?

How Do I Treat Duckweed?

Tim – Rock Hall, MD

Duckweed is a very small floating plant about the size of a pencil eraser. It has shoe-sole shaped leaves with a small, hair-like root hanging below. Since duckweed floats on the surface of the pond, it is commonly mistaken for and treated as if it is algae. Unfortunately, algaecides have no effect on duckweed but there are a couple treatments you can do to keep the prolific duckweed at bay.

The Short-Term Solution
To treat duckweed as well as other aquatic weeds on a short-term basis, you can use Pondweed Defense® or RedWing™. Both are great for a one-time treatment or for spot treating. These are, however, only short-term solutions for duckweed. Due to their aggressive nature, duckweed can grow back in as little as 3 to 4 weeks. This is why we suggest a longer-term solution.

The Long-Term Solution
One of the only products on the market to provide long-term, season-long control of duckweed and other aquatic weeds is called WhiteCap™. Instead of having to spray the plant directly, WhiteCap™ is sprayed directly into the water. WhiteCap™ works by preventing photosynthesis in aquatic plants and by doing so causes them to slowly parish. Treating duckweed and other aquatic plants in this fashion allows for complete control of the entire water body for the season instead of just a few weeks.

The geese are already showing up at my pond. How can I stop them from making my pond home? | Pond & Lakes Q&A

As the warmer weather rolls in you will begin to notice a gathering of geese around your pond. While ponds are great for drawing wildlife some pond owners are hesitant to let geese congregate in their yard. How can geese become a nuisance in your pond and what can you do to keep them away?

If you have ever been to a park that is frequented by geese you will notice that they tend to cover the entire ground with droppings. This abundance of waste is less than ideal for those of you that swim in your pond. The additional influx of organic waste can also cloud your water and promote increased weed and algae growth. Geese can also carry problematic items from neighboring ponds. Duckweed and leeches commonly hitch a ride on the feet of water foul like geese and ducks which are then introduced into your pond as they loiter in your yard.

To prevent your pond from becoming the local hot spot for geese this season try placing a pair of floating swan decoys in the water when the ice melts. As geese are extremely territorial they will spot the swan decoys as they fly overhead and skip over your pond as they search for a less-crowded water body. Coyotes, Alligators and motion activated decoys are also available forms of predator control if you are looking for alternative options.

Whether or not you should let geese use your pond depends on what you want to use your pond for. If you use your pond for recreation or decorative purposes it will be in your best interest to keep them away. If your pond exists for reasons outside of recreation and you enjoy the additional sights and sounds of geese in the summer then rest assured that your feathered friends will be relieved to see your decoy free pond.

Breaking the Ice on Your Spring Pond Projects
With the sun shining brighter than ever and the snow finally disappearing, most of us pond guys and gals are itching to throw on our waders and dive into our ponds — figuratively of course.

As the Saying Goes, “An Ounce of Prevention…”
Ok, so none of us really want to spend our spring and summer in waders pulling weeds and tending to unruly ponds. So what can you do to ensure your Winter/Spring transition is smooth and enjoyable? As the saying goes, “An ounce of prevention is worth a pound of cure.” This is especially true in the months to come. Following some easy procedures will keep those waders in your closest and a smile on your face.

Do Your Pre-Spring Cleaning
Walk around your pond and pick up any debris that has made its way into your yard and around your shoreline. If left to sit, this clutter will turn into a food source for algae in the spring. Cut back any weeds or unwanted vegetation growing around the pond while it is still dormant, keeping it from taking over your pond as the temperatures rise. Now is also a great time to inspect and clean your aeration system cabinet and, if the ice has already melted in your pond, the plates as well. This would be a good opportunity to move the plates back to the deeper areas of your pond for summer aeration, if you happened to move them to shallower areas during the winter.

Shaken, Not Stirred
With all of the dye, beneficial bacteria, and occasional algaecide we’ve added to our ponds over the seasons, you just may be qualified to tend a tiki bar at your pond. While your PondClear™ and EcoBoost™ get the back shelf for the winter season, you should be adding dye to your pond year-round as algae can still grow under a layer of ice in the colder months. If you have not been doing so, add your dye now to reduce the amount of sunlight available. Preventing algae growth now will keep you from fighting an algae bloom in the spring. Your PondClear™ and EcoBoost™ treatments should continue once the water temperature is above 50º F. For those of us who suffer from Duckweed, as spring approaches, you will want to have your WhiteCap™ on hand and ready to apply come mid-April so it has a chance to go to work and prevent weeds from growing throughout the season.

Take Inventory
Kris Kringle is not the only one checking his list twice over the winter. Pond guys and gals everywhere should be checking their remaining ClearPAC® and necessary weed control products and replenishing these items for the upcoming season. Inspect your tools and decoys to make sure they are in working condition. With everything in working order and ready to use, you are now ready for anything spring sends your way. All that’s left to do now is enjoy your pond!

Controlling Pondweeds: Duckweed – Pond & Lake Q & A – Week Ending March 28th

Picture of Duckweed Floating in a Pond.

Pond & Lake Q & A

Q: Last year I had an uncontrollable case of duckweed in my pond. It covered my entire 1/2 acre pond! I’ve heard of your product called WhiteCap and wanted to use it this spring. I don’t see any signs of duckweed yet, but was wondering if it is too early to treat.
– Cameron of Michigan

A: Duckweed can take over a pond. This prolific grower can come from many sources although most commonly brought in on the feet of waterfowl such as ducks, geese or even herons. The small plant can stick to the feet or the feathers of such birds and be carried for miles. Duckweed can start out slow and in some cases take several seasons to become a problem, although I would recommend treating for it as early as possible.

There are a few options when treating duckweed. You can use a fast-acting aquatic herbicide such as Ultra PondWeed Defense® although this will only give you temporary relief and require multiple applications of spraying the duckweed directly. These are not usually suggested unless your treatment areas are not contained or you have heavy water turnover. When possible I always suggest Sonar™ A.S. since it is the least expensive method of treating an entire pond, is easy to apply and lasts an entire season.

We recommend to use 32 oz or 1 quart per surface acre (4-6′ deep) when treating for duckweed. This means Cameron’s 1/2 acre pond can be treated with just 16 oz of Sonar™ A.S.!

To answer the question above, treat with Sonar™ A.S. in the early spring before the duckweed even appears. This will allow you to get ahead of it before it reaches the surface. Although you don’t generally see it Duckweed is actually growing at the bottom of your pond long before you see it at the surface.

There are also other nice benefits to Sonar™ A.S. such as: It works very slowly so there is no chance of oxygen loss that could harm your fish or other aquatic life. Sonar™ A.S. is also very effective at controlling most other nuisance aquatic plants. So when your treat for your duckweed you will be controlling most other species as well.

Please Note: Sonar™ A.S. needs to stay in your pond for up to 90 days. It is not recommended to use it in ponds with a heavy overflow or when during times of heavy rain. If you are unsure of your pond’s turnover (or amount of water that is exchanged) use Nature’s Blue™ Pond Dye to shade the water column and track the time it takes for the color to disappear. You may also use Nature’s Blue™ Pond Dye during a Sonar™ A.S. treatment to track turnover and shade the pond from sunlight which can also reduce the life span of Sonar™ A.S.

There is an Oil Slick Film Covering My Pond. How Do I Get Rid of It? – Pond & Lake Q & A

Algae, Duckweed, Watermeal & Pollen Identification

Q: There is a brown rust-like film/oil slick covering my pond. Do you have an idea what this might be and how to get rid of it? - Several Customers

A: There are several things this could be: Algae, duckweed, watermeal or pollen.

Determining if Algae is a Problem: Filamentous Algae will float around the pond’s edges in mats while Planktonic Algae will make the whole body of water to look like a “pea soup” green color. If this is the case, using Algae Defense® Algaecide will provide quick control. Follow up with PondClear™ for long-term clear water.

Determining if Duckweed or Watermeal is the Problem: Duckweed and Watermeal are very rapid growers and will cover an entire pond if they get out of control. Looking to the pictures to the left, you can see that Duckweed is a small plant the size of a pencil eraser, while Watermeal is about the size of the tip of a pencil. If you determine that you have Duckweed or Watermeal. Your only long-term option is Sonar™ A.S. for Duckweed and Clipper™ for Watermeal. If you only require short-term control (3-4 weeks) for an event or party Ultra PondWeed Defense®” may be used.

Determining if Pollen is the Problem: What may look like a greenish, brownish algae, may actually be pollen. Pollen may even cause an oil-slick or film on the surface of the pond. There is no magic product that will give you a quick fix. Many times a heavy rain will settle it to the bottom. In many cases if your pond receives good circulation from an aerator or fountain you will not see pollen becoming much of a problem.

Controlling Duckweed & Watermeal – Pond & Lake Q & A

Q: I think I have duckweed and watermeal. It’s taking over my pond! I can’t seem to get ahead of it! What do I do?
- Several Customers

Picture of DuckweedA: Duckweed and watermeal are very prolific growers and can cover a pond before you know it. When covering a pond it can look like algae, but up close you can see it’s not (see pictures on the left). You can try to rake the duckweed and watermeal off the pond’s surface but more will be back within the week. The absolute best way to get rid of duckweed is to use a product called Sonar™ A.S.. The best way to get rid of watermeal is to use a product called Clipper™. Sonar™ A.S. works by inhibiting the weed’s ability to produce carotene. Without this ability, chlorophyll is rapidly degraded by sunlight and the weeds die. The only water use restriction is a 30 day irrigation restriction.

Both Sonar™ A.S. and Clipper™ will also get rid of many other submerged weeds in the pond and will produce season-long results in as little as 30-45 days.
