There is no need to dig up the dead cattails. Just cut the plants at the ground level and let them decompose. However, please wait 3 - 4 weeks after herbicide application to ensure the product has translocated to the roots of the plant before cutting.
For our customers in New York, New Jersey, Connecticut, Maine, California and Washington state, SePRO is currently limited in the direct selling of regulated aquatic products. Revive and SePRO Blue can be purchased and used in all states. Please contact your SePRO pond advisor for more details.
Aquatic gardens (smaller than 50' x 50') can be effectively treated with SePRO pond products. Simply multiply the length x width in feet and divide by 43,560. Multiply this number by the recommended rate of product per acre.
Always check with your state and local regulations, but in most cases a permit is not needed for privately-owned ponds. We recommend checking with your local extension agent prior to applying products. You can visit the United States Department of Agriculture web site for information on how to contact an extension agent in your area.
Start by controlling algae and weeds. Most mosquitoes thrive in water that is stagnant and filled with algae and weeds. By reducing the amount of algae and weeds, you will reduce the mosquito population. After reducing the algae and weeds, you can also add top-feeding minnows to help control the mosquito population. In clearer water, they will be able to access and feed on the mosquitoes. There are also mosquito insecticides that can be used to control mosquitoes.
Aquatic plants are identified based on their location in the environment. See the most common aquatic weeds by clicking on the "Weed ID" link at the top of this page for detailed pictures and descriptions. If you have some trouble with identification, most plants can be identified over the phone by calling your SePRO pond advisor.
Yes. With AquaPro you will only control the plants you spray. If you do not directly spray the cattails they will not be affected by the treatment. AquaPro is a contact product.
Waterfowl and roaming animals carry floating plants such as duckweed and watermeal from pond to pond. Submersed vegetation can get into to your pond the same way, or be washed in from other ponds. Some people introduce plants into their ponds for aesthetic purposes and find, in a short time, these non-native species over take the pond and need to be removed.
Eutrophication is the natural aging process of a pond. A pond begins as a well-balanced ecosystem of plants, fish and invertebrates. Over time, however, watershed run-off often produces nutrient overload, which can contribute to an overabundance of vegetation, reduce invertebrates and crowd out fish populations.
Planktonic algae blooms, which take place in warm water during summer, are not present in cold water during the winter.
Excessive nutrients in bodies of water are becoming problematic in promoting algae growth. Blue-green algae may cause illness and in some cases fatalities in pets, livestock, and wildlife. Exposure to or ingestion of this algae may also cause a variety of discomforts in humans. Algae contamination in drinking water can discolor the water and cause unpleasant taste and odor, and may impart a distasteful flavor to fish. Decomposition of decaying algae in late summer commonly causes a fish kill due to rapid dissolved oxygen depletion.
Herbicides labeled for aquatic use are non-hazardous to fish, pets and the local wildlife when used in accordance with the product label.
Problems, should they occur, are caused by misuse of herbicides, such as:
Exceeding recommended label rates
Exceeding application recommendations
Using products not labeled for aquatic use

Prevention is the key to avoiding costly control measures to eliminate a nuisance duckweed problem. Nutrient reduction and getting some motion in the water through a technique such as bubble aeration are two key preventative techniques. If duckweed does reappear, it is much easier to control the tiny emerging plants than the mature plants; so the best time to take action is at the first sign of infestation.
Duckweed is moved from pond to pond by animals and waterfowl such as ducks and geese. Once duckweed is introduced into a waterbody, it can spread rapidly if conditions are right. Ideal growing conditions are still or slow-moving water that is high in nutrients such as nitrogen and phosphorous.
There is a simple test: submerge your hand in the plant matter. If the mass separates, it is probably duckweed or watermeal. If the mass does not separate, it is probably algae. Algae is usually slimy and stringy and forms mats on the surface of the pond. Duckweed appears to form mats, but is a system of small plants the size of pencil erasers that float on the surface of the water. Duckweed resembles clovers floating on the surface of the water and has small white roots hanging from the bottom of the plant.
Green water or "scum" on the top of your water can be any of several things: duckweed, watermeal, or algae. Frequently these are mistaken for each other. Duckweed are very small floating leaves with a small root while watermeal resembles green sand. Filamentous algae form dense mats that float on top of the water and planktonic, or blue-green algae, give water a 'pea soup' consistency.
