Hydrothol: Don't Get Burned!

Hydrothol is a selective, quick-acting, contact herbicide and algaecide that can burn your skin.

Natalie is a homeowner in Charlotte, NC and has a farm pond. She was getting ready to have a party in a few weeks and wanted to make sure everything looked beautiful. She went out on her dock to check on her pond and noticed some weeds growing up from the bottom or was it algae? After contacting the Clemson Extension office they determined it was Sago Pondweed, Small Pondweed, and Chara.

In just a few short weeks over 60 percent of her pond had been taken over by the large beds of algae and the chara. And it was starting get really embarrassing.

Finally, after trying every product in the catalog and from Tractor’s Supply, she became a member so she could insure a healthy and beautiful pond. No longer would she have to worry about it being an eye sore for anyone visiting.

We knew Hydrothol would be best for her pond. Hydrothol is a selective, quick-acting, contact herbicide plus algaecide. It controls submersed weeds and kills algae in lakes, ponds, irrigation canals, and drainage ditches.

Hydrothol can be toxic to fish. So slowly treating the edges of pond first is essential. When treating the edges, fish will move away from the side that’s being treated. Within a few days, before Natalie’s guests arrived, her pond was back to being healthy and beautiful.

Hydrothol has been successfully used for over 30 years. It’s primarily used as an algicide and is the only registered broad spectrum organic aquatic algicide available today.

It can be used in combination, in a rotation or as an alternative to copper for control of algae. Aquatic herbicide applicators often refer to mixing copper and hydrothol as a “HOT” mix, because of the heat that is created by it reacting with the copper in the tank.

Hydrothol will burn your skin fast. So beware of wind blowing it on you, splash or dripping down your back with a leaking spray tank lid. “Ouch! It’s the worse sunburn you have ever felt.” And always use gloves. Even when it’s 95 degrees outside and you are sweating.

Due to the fast activity, it can be efficiently used in slow-moving water, such as drainage and irrigation canals. Also, spot or marginal treatments are highly effective against noxious weeds and algae in lakes and ponds. Since it does not bind to the suspended sediment or organic matter, it’s effective in murky or muddy water.

Why both granular and liquid products? Granular products control both bottom growing or rooted weeds and algae. Liquid products control weeds and algae at or near the surface or have accessible foliage. You can pretty much guarantee that in most cases, either form will be successful.
