Duckweed has long been a problem for backyard ponds, lakes, and other waterfront areas. The small, floating weeds can quickly take over a body of water, blocking out sunlight and making it hard for native aquatic plants to survive. While there are many ways to try and combat duckweed, one of the most common solutions is Round-Up, a popular herbicide. But is Round-Up an effective tool in the fight against duckweed?

Round-Up is a powerful weed killer, and it can be used to combat a variety of weeds, including duckweed. It works by killing the root system of the weed, preventing it from taking hold and growing. When applied to duckweed, Round-Up can be highly effective in killing the weed. However, it is important to note that Round-Up can also kill other aquatic plants, so care should be taken to only apply it to the areas affected by duckweed.

How To Use Round-Up Against Duckweed

If you're looking to use Round-Up to kill duckweed in your pond or lake, there are a few things you'll need to keep in mind. First, make sure to use a herbicide that is specifically designed for use in aquatic areas. This will ensure that it won't have any adverse effects on other aquatic plants.

Also, be sure to read and follow all instructions on the packaging. This will help ensure that you use the herbicide safely and effectively. When applying the herbicide, it is important to keep the area well-ventilated, as the fumes can be dangerous.

Finally, it is important to note that Round-Up may not be the best solution for all ponds and lakes. If the area is too large, or if the duckweed is too widespread, you may need to consider other methods of control, such as manual removal or biological control.

What Are The Benefits Of Round-Up?

One of the main benefits of Round-Up is its low cost. When compared to other methods of duckweed control, Round-Up is relatively inexpensive and can be applied quickly and easily. It is also a fast-acting herbicide, so it can take effect within days of application.

Another benefit of Round-Up is that it is non-selective, meaning it will kill any plant it comes into contact with. This can be beneficial in cases where the duckweed is widespread or hard to control with other methods.

What Are The Disadvantages Of Round-Up?

One of the main disadvantages of Round-Up is its potential for runoff. If the herbicide is not applied correctly, it can run off into other areas of the pond or lake, killing other aquatic plants. This can be especially damaging in areas with a fragile ecosystem.

In addition, Round-Up can be toxic to humans and animals if it is ingested. Care should be taken to keep the herbicide away from children, pets, and other living things.


Round-Up can be a useful tool in the fight against duckweed, but it is important to use it carefully and responsibly. If used correctly, Round-Up can be an effective way to kill duckweed quickly and easily. However, it is important to be aware of the potential for runoff and toxicity, and to take the necessary steps to protect the environment and those living in it.
