Sonar Ready-To-Use RTU represents an exciting new era in pond weed management for the do-it-yourselfer! It is generally safe for fish and other aquatic life when used as directed. It slowly kills the aquatic plants, so fish kills aren’t a problem.

The innovative new RTU formulation allows anyone to make water usable for recreation, bring fish populations back into balance and restore property values. Its so simple that applying Sonar RTU doesn't require any mixing, special spray equipment or a boat simply open the bottle and treat from the shoreline.

Many pond owners consider duckweed to be their toughest aquatic weed problem. Duckweed is a very common nuisance aquatic weed that is spread from pond to pond via waterfowl or other wildlife. While it is commonly mistaken for algae, duckweed is actually a tiny plant with an explosive reproductive capacity that can completely cover a pond in just a few weeks to the point that the infested waterbody resembles a golf-course green. Fortunately, no other aquatic herbicide is more effective on duckweed.

Sonar provides complete, long-lasting control of duckweed and other stubborn unwanted aquatic vegetation

32oz. Container Ready-To-Use

What Sonar RTU Controls:

  • Alligator Weed
  • American Pondweed
  • Bladderwort
  • Coontail
  • Creeping Water Primrose
  • Curly-Leaf Pondweed
  • Duckweed
  • Eurasian Milfoil
  • Watermeal & Other stemmed Plants

How Sonar RTUWorks
Sonar RTU manages undesirable aquatic weeds for a year or longer and is recommended for use in water bodies with soft or muck bottoms. Sonar RTU contains 3.79% fluridone in an easy-to-use liquid formulation that is applied straight from the bottle.

Sonar works by stopping photosynthesis, which robs target plants of their ability to make food. Target plants turn white and gradually die over a period of six to twelve weeks. Unlike other aquatic herbicides, Sonar has no restrictions for swimming, fishing, boating or livestock use, even immediately after application. Check the label for irrigation precautions.

Sonar is the world's leading brand of aquatic herbicide for the selective, long-term control of undesirable aquatic vegetation. With an unmatched dedication to advancing the science of aquatic plant management, researchers at SePRO Corporation have integrated fifteen years of laboratory research, field expertise and formulation innovation into Sonar RTU, the first Sonar product designed specifically for small pond and lake owners.

Now you can benefit from time-tested application methods and materials developed by SePRO scientists all in one convenient package you'll use right on your waters edge.

Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy. So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain. So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more! So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that.

High quality replacement clips. Highly recommend.
I used these when replacing the headlight assemblies on my 2011 Honda CR-V. A few clips were already missing before I even started taking the bumper off, and of course a couple more didn’t survive the job. These fit perfectly and snapped right in with no issues. If you’re missing clips or break some while doing a repair, these are a simple fix that gets everything secured again. Very good deal.
