How To Control Duckweedduckweed

A common annoying aquatic weed which can invade ponds and lakes is known as duckweed. Duckweed has the ability to spread at an alarming rate and can infest a pond or quiet lake in a matter of days after first being established. Duckweed can be a major nuisance for pond owners due to its knack for turning an an aesthetically pleasing pond into an ugly mess.

Duckweed is a free floating pond weed which is often confused as algae because of the dense mats they can create on the surface of water. Duckweed is usually found on wetlands that are rich in nutrients. The characteristics of duckweed include shoe-sole shaped leaves with a small hair-like root hanging below. Duckweed looks very similar to a four-leaf clover and is roughly the size of a pencil eraser.

Duckweed is known to spread onto ponds by migrating birds who have the plant stuck on their feathers. If left to its own devices, duckweed can quickly take over the entire pond surfaces, decreasing oxygen levels necessary for fish and desirable aquatic plants to survive. Duckweed is nearly always found along with a smaller plant called watermeal. Both of these invasive species work together to overtake vulnerable bodies of water quickly when conditions are ideal.

If you have duckweed growing on your pond or aquatic property, there is an effective way to deal with them by using aquatic herbicides carried by Solutions Pest and Lawn

How To Get Rid Of Duckweed: 3 Step Solution

While duckweed can be frustrating to have growing on your lake or pond, they are actually quite easy to remove. The problem is keeping them gone. While mechanical or physical options like skimming or raking the leaves off the pond surface works to get rid of them, if you have a rather large pond or body of water to deal with, this could be a laborious task that will be time-consuming. By following the 3 step process we have laid out below, you can successfully eliminate duckweed safely and conveniently.

Step 1: Before introducing chemical applications to the equation, perform a thorough analysis of the body of water where the duckweed is present. Using chemicals to treat your pond or lake can be risky so you must consider all the variables like pond size, the ecosystem, the aquatic life in the water that you want to have around like vegetation and fishes etc. As we mentioned above, duckweed thrives in waters that are nutrient rich. By address the reasons why there is so much richness in the water and working to reduce the amount of sediment can complement using aquatic herbicides to eliminate the duckweed problem.  Aeration is one way to purify your water and decrease the need for chemicals.

Step 2: Once you have purified the water, you can then move on to chemical treatment. Select a high quality aquatic herbicide which we carry a number of here at Solutions. You will then need to determine the application rate as well as time your application at the right time and temperature in order to successfully eliminate duckweed.  Applications should begin the earliest possible of spring when duckweed first appears. When applying herbicides you should also make sure you have on the proper safety equipment such as protective eyewear, gloves and long sleeve clothing to protect you from possibly coming in contact with chemicals.

Step 3: Apply the chemical treatment to the water using a backpack sprayer or hand-pump sprayer. Exercise precaution and treat your pond in sections to prevent the chemical from harming other life in the water. Treat only half the pond's surface at a time. During hot weather or when treating heavy growth, it is important to treat no more than ¼ of your pond at a time and wait the full 14 days before re-applying. We want to emphasize that unless something is done to reduce the nutrient richness in the water, this duckweed will continue to be a returning problem.
