    5 of 5 stars  duckweed killer
    By Glenn in Buffalo, NY on 07/29/2011
    Verified Purchase

    product worked great. i sprayed the pond to kill the duckweed and in a few days it was gone. Be sure to follow directions on label and add the surfactant (purchased seperately). A little goes a long way. I have a 1/4 acre pond and used about 1/3 of the bottle to kill my duckweed problem which covered 1/2 my pond.

    5 of 5 stars  Used on 1/4 acre pond. (in East central Fl)
    By R.i in Scottsmoor, Fl on 05/05/2013
    Verified Purchase

    Worked great.....Pond was 90% full of duck weed.....I mixed 1.5qts reward with 30 gallons water. Plus 1cup of Enhance (same as soap) to help float the Reward on the pond surface...... I sprayed 1/2 the pond (using 10 gallons of my 30 gallon mixture). A week later I sprayed another 10 gallons on the remaining duckweed.... That leaves me 10 mare gallons for the diehards....

    Seems to be doing a good job but we had to stop to get rid of turtles that are in the pond. It would be helpful if there was a label telling you how much to use when you need to mix it with water to kill a certain weed, but the product works well.

    Have been using this product to control Alligator grass and Duckweed as well as other aquatic weeds in my pond for several years. Best I have found. Have used anywhere from 2 - 12 ounces/gallon and found that 4/gal seems to be adequate in most cases. Not harmful to pond inhabitants.

    5 of 5 stars  Duckweed took over my pond
    By Wayne in Pearl River, Louisiana on 12/30/2016

    This product works great. My whole pond looked like a golf course. A friend told me about this product. I started using reward and within 24 hours I started to see results. This stuff is amazing. I used 3ozs of reward and 1 table spoon of surfactant per gallon of water. This covers about 1000 sq ft. You should only do about 1/3 of your area at a time, because of the fish and turtles. I find the best time of the day is between 10am and 2pm. I'm so excited to finally have my pond back. I wish I could show some before and after pictures lol. Hopefully this helps

    4 of 5 stars  Dead "seaweed"
    By John in Little Rock, AR on 07/10/2015

    In the husband wife tug-of-war on killing our pond weeds, Reward seems to be the exact ticket. The wife wants the "seaweed" not to show and I want it to remain for baby fish to hide in. The Reward knocks it down and thins it out, but it always comes back. I have to spray twice a year to keep it in check. Wear gloves and glasses as suggested. I have been impressed and pleased with DMOPC from all aspects...advice, product and service quality. I have referred friends to DMOPC.

    5 of 5 stars  Reward
    By Dave in Columbus, Indiana on 07/17/2014

    Bought because of high rated reviews. Used on aprx 3 acre pond. had heavy moss and lily pads on top and heavy sub surface growth. It knocked top growth down in two days. any thing even the lilly pads turned brown next day. You know quick if the spray reached reached its target. I harder to say how well it worked on subsurface growth. I had growth that seems to be killed back but it did not decay seemed to turn brown but just seemed to go dorment. I am now purchasing a aqua ( landscape) rake to physically remove the sub surface weeds. 36 - 48 in rake some thrown some with long extension handle are out there. I bought a 48 inch aluminum landscape with 6-7 ft handle. It has not yet arrived. Will add extension to it my self, if feel I need to. Back to rewards chemical It is a powerful herbicide. Like a Roundup concentrate, concentrate. Note I had cattails at one time. Knocked those out with Roundup. It worked great. Was a easy cheap way to get rid of cattails.

    4 of 5 stars  Combo treatment for pond
    By John in Little Rock on 10/08/2012
    Verified Purchase

    So far, so good. I have a small pond with unwanted "growth" in it and was told that Reward in combo with an algaecide would cure it. I treated as suggested by my referral friend and it appears after 4 days the plants are dying and I have no dead fish. If it finishes like it has started, this stuff is worth it's weight in gold because my bride was torqued-out about me letting these plants grow! Thanks for the great product and ultra-quick delivery.

QWill Reward Herbicide hurt all the babies this time of year, such as ducks and turtles?
frogs, not to mention fish, etc? It seems like the babies want to stay by the edge of the pond where the product would be applied.

A

Reward Landscape and Aquatic Herbicide can be used around bodies of water that contain aquatic life as long as you are following the product label rates and instructions. We would recommend treating the area when animals are least likely to be present. There are no swimming or fishing restrictions when using Reward. Other restrictions can be viewed on page 11 of the product label here.

05/21/2017 Tony from Wilmington, Oh

QHow much Reward Herbicide do I use per gallon of water for treating pondweed?

A

To control submersed weeds such as pondweed using Reward Landscape and Aquatic Herbicide, we recommend that you apply 0.5-2 gallons per surface acre (4 ft depth). For heavy infestation 2 gallons. For best results you will retreat on†14-21 day intervals.

QHow long will it take for duckweed to die once treated with Reward Herbicide?

A

How long it takes duckweed to die after treatment with†Reward Landscape and Aquatic Herbicide†depends on when applications were started. †Duckweed can multiple†every day so can take multiple applications to get control of. †What is sprayed should die but anything missed can start to grow again in a few days. †Treatments should begin as soon as the duckweed starts to grow in the spring or early summer in temps between 68-86 degrees is ideal.

QWhat are the mixing instructions for Reward Landscape and Aquatic Herbicide?
how to mix for water primrose

A

The amount of†Reward Landscape and Aquatic Herbicide? to water ratio will depend on what you are treating and the type of area you are treating. We always have the†product label†available on our website for your convenience. The product label on our site contains the same information that is in the booklet that you received with the product. The Product label also states that the amount of product you use will vary by whether you are doing a spot or broadcast treatment. Keep in mind, for herbicides the amount of water you use is not as important as getting the correct amount of product over the correct amount of area. The water acts as the carrier so whether its in 2, 15,50 or 100 gallons, all are correct if you properly disperse it.†

However, water primrose is not on this product label. †

QHow often can I spray Reward and Surfactant on my lake for Duckweed?
I am spraying sections at a time, to protect wildife.

A

For spot treatments using Reward Herbicide, you can re-apply every 2 weeks as needed. If you are doing a broadcast treatment, the label does not specify a time frame in between applications, however, we would recommend waiting at least 2 weeks to do another broadcast application so that the product has time to work.

QWill Reward Landscape and Aquatic Herbicide kill my new Grass Carp 10"?
1/2 acre pond lots of milfoil weeds. I also have new this year bass, catfish, bluegill, and shellcrackers

A

When appliying Reward Landscape and Aquatic Herbicide, you†need to be sure not to treat your entire pond all at once. Doing so will probably result in dead fish. Treat about 1/4 to 1/2 of your pond at a time - following the product label, and your fish should be fine. This will certainly take care of the milfoil weeds you have.

QWill Reward Landscape and Aquatic Herbicide work on American Lotus?
Have a 6 acre pond/lake. Need help with a herbicide that will work on both lotus and coontail.

A

Reward Landscape and Aquatic Herbicide is not labeled to control American Lotus, but we do carry Rodeo that is labeled for American lotus and several other aquatic weeds. Reward is the only herbicide we currently carry that is labeled to control coontail. Please keep in mind that this weed can be very difficult to control, and a combination of both chemical control and physical removal will yield the best results.
