Duckweed, among other things.
Co-op I called said they could order it, and it would be $300/gal. I was wondering if was cheaper somewhere where they sell enough to keep it stocked.

at that price you may want to do some research on Rodeo.. a fish friendly alternative to round-up...{ i think they are the exact same product, just that rodeo has the nads to cover any liability if any occurs.but you pay for that label}

Thanks Judge, we've not had very good results with our Rodeo/2-4,D cocktail on the duckweed, but it does a good job on everything else.
If this Reward does what the label says it will do it would almost be worth the $300/gal, but I'm skeptical.

Call me at the office and I'll get you Reward at half the price and give some other options.

Both Rodeo & Roundup contain glyphosate, but the surfactants are different. Rodeo contains a surfactant that is not toxic to aquatic organisms. Thats why Rodeo is labelled for aquatic uses and Roundup is not.

Rodeo and Roundup contain the exact same active ingredient -- glyphosate. Neither will have a surfactant mixed in. If you by a ready to spray, already dilluted version it may have the surfactant mixed in but if you buy the real deal it does not.
I may be wrong, but I spray a lot of the Rodeo and the generic verisions and I have to mix in my surfactant. I also have a lot of clients that have sprayed plenty of Roundup in ponds. The difference is they spent several millions getting the government to approve Rodeo for an aquatic label.

Glyphosate is not itself toxic; but some surfactants commonly used with it ARE toxic to aquatic animals. Most (probably all) versions of Roundup have a surfactant in them.
The toxicity of the surfactant to frogs and other aquatic animals is the reason that Roundup is not approved for aquatic use. There are several scientific studies. Here is one

You are correct that getting an aquatic label is expensive!
Rodeo is labelled for aquatic use because it does NOT contain a toxic surfactant. If one uses a surfactant, make sure its an aquatic-labelled one.
Hope this helps!

J,
I may be wrong and please correct me if I am, but... when I purchase any type of glyphosate it does not have any surfactant it in. If it does why do I need to purchase a seperate surfactant to mix in with it so that it will "stick" to the plant?
I am not buying a little spray bottle that is sold at a garden store. I buy it in 2.5 gallons jugs and have yet to buy any with a premixed surfactant. Are you referring to the inert components??

Several glyphosate versions, Roundup included, have surfactant in them. Several of the cheaper models do not, and it has to be added. Some glyphosates are 4 lb material, some are 5 lb. Be careful what you are buying when somebody gives you a "good" price, you may be buying 4 lb glyphosate with no surfactant.

Pondman you are mistaken. RoundUp contains a surfactant, but Rodeo does not. Rodeo is aquatic safe, but RoundUp is not. Rodeo is aquatic-labelled, but RoundUp is not.
It is ILLEGAL to use RoundUp on standing water; this is an off label use.
I have confirmed this (in person) with a senior scientist with a major glyphosate manufacturer. This is fact, but I encourage you to do your own research.
Good Luck!

Given that I'm in the business of spraying aquatic weeds I only use aquatically labeled stuff. I can not afford to get caught using something off label.
Just out of curosity, what about the glyphosate products that are not manufactured by Monsanto. Do all non-aquated labled glyphosate products contain a surfactant?

"Always read the label"
Herbicide labels are very important but rarely read. There are many variations of glyphosate mixes. Round-up is glyphosate with NO surfactant. Round-up Ultra, Round-up Weather Max, Round-up Ultra Max,Round-up Original, etc., etc. are all glyphosate + surfactant mixes. The generics most all have surfactant in them because they are sold in bulk for ag purposes most of the time.
