Product Info

Hydrothol® Granular should be spread evenly throughout treatment area when plants are present. Most effective when applied on a calm day. When applying Hydrothol® Granular aquatic herbicide, we recommend using a broadcasting spreader.

Hydrothol® provides control where you need it, in the application area, not away from the target area. For this reason, Hydrothol® is a valuable tool in improving access to the water for recreational activities such as swimming, fishing, and water skiing. Hydrothol® is effective in muddy or murky water because it does not bind to the suspended sediment or organic matter. Hydrothol® is also an effective algaecide.

Additional Info

Hydrothol® Granular is a granular aquatic herbicide and algaecide for lakes and controls nearly all types of lake weeds, including milfoil and hydrilla.

  • EPA Approved
  • No swimming or fishing restrictions
  • Works best on firm, sandy lake bottoms

We recommend using Hydrothol® Granular and MuckMaid®. Hydrothol® Granular will control submerged weeds and MuckMaid® will consume nutrients and silt that help aquatic weeds grow.

    Love the granular pellets. Easy to apply from the dock with a broadcast spreader. We have curly – leaf pond weed, milfoil and hydrilla. Also a little algae along the shore. This works great on all. We apply early summer and early fall.

    Will this work in water and on weeds like bull rush wild rice?

    What aquatic plants are resistant to this product so we can plant them and return oxygen to the lake?

    Do you have sales in Europe?

    Been a user for 4 yrs. Eliminates 95% of the weeds allowing for easy pulling of the remaining weeds.

    Works well to control weeds around my dock and lift. I have used it for a few years now, when looking at neighboring slips mine is by far the clearest. Would have given 5 stars but some weeds still manage to grow. Cheapest control I have found though.

    This is my second year using HG and it seems to have a cumulative effect since there we very few weeds this year compared to last. For reference, we’re located on Little Pine Lake on the Whitefish Chain in Crosslake, MN

    Hard to say much more than it simply works if you have the weeds that are in its list to control best.

    We have used HD granular for 4 years now. While it worked on the weeds the first year or so, now it controls none of them. Probably have eliminated the susceptible weeds and now have the more resistant ones left.

    First of all, Shipping is outstanding! I ordered on a Sunday and received product on Tuesday. Only 2 days, unheard of. I like the product, works pretty fast, will have to treat one more time pretty soon.

    I like the price compared to other brands and it works just as good! Seeing less weeds this year, second year of using it and i will continue to purchase it if price doesn’t go up. I’d like to see if there is something that treats the “crab grass” type of weed, it gets brown but we go in and have to rake it out and the roots are deep! Leaves a big whole when it comes out finally.

    Works within two weeks in my pond.

    Easy to apply, I’ve been using this product for about 10 years. Apply once in the late spring, and its good for all year.

    This stuff is AWESOME. I NEVER leave reviews on something unless it is a complete bust or amazing and this is definitely amazing. We have a 15 acre lake on our property in Central Texas and the hydrilla was awful. We used this stuff and it is the first time I could swim off the boat ramp, out to the middle without touch the hydrilla!! Will be buying more next year!

    My experience is similar to the June 8, 2021 reviewer. We purchased in may 2020. At that time the website stated: Water use restrictions— Swimming zero days Fishing. Zero days Drinking water. Zero days When the product arrived it openly states it can kill fish & should not be used within 500’ of your water intake. Jenni Oxley was extremely slow to reply & did so only after I sent multiple emails. She was rude & said she had no control of the website information. Her comment was that I should have read the labels available in the website. Since the website said the water was drinkable at zero days, silly me did not think it necessary to read the labels. Her suggestion was that I return it at my expense which did not seem fair to me. They have removed drinking water from the website but I do have a screenshot with the 2020 water use restriction. Very disappointing experience.

    I read a lot of comments and all i could find about this product before buying it. I buy it and get the bag out and read it it and BAM HIGHLY TOXIC TO FISH. WHY can`t they put that in the 1st. line, that way people can go on to find something that`s NOT TOXIC TO FISH. Now I have to do the return thing and wait on that,then re- order something that WON`T KILL MY FISH I HAVE SPENT A FORTUNE ON.

    i put a comment on here about them not putting on the description that it is toxic to fish. I emailed Katie and she called me back the next day. I was shocked,lol. She told me I could return it, or I could use it in small amounts, and do sections of my pond at a time. I have done 2 sections now and this stuff works great.I`m very pleased with the results. thanks for being so helpful and kind.
