Surfactants and Generic Gylphosate

ryanwheelock · Jun 9, 2010

Was reading older post when I read this, "When you use the Roundup branded it had the surfactants in the mix. With the generic you are going to have to add them or you risk a poor kill because no surfactants are in the generic."
I sprayed my RR corn with the generic at a rate of a bit over 1qt per 10 gal. of water per acre. Didnt get much of a kill. Its mostly what I've always called quack-grass thats about 2-3 inches tall and pretty thin. Should I add a surfactant next time??? What would I ask for at the dealer??
Also I've got hard water and read that I should add some AMS to the mix. Good idea??
Just want a better kill after I spray. Its my first corn crop and want to get the weeds under control before they get taller.
Thanks
Ryan

Ryan----I planted my first SOYBEANS this year with Round up Ready seed.....

I found a post emergent weed killer called Pronto "Big and Tuff" that will work with RR soybeans...about $35 gallon and mixes at 3oz/gal H20...you are using on CORN, so thought they may have a product that may be suitable....

My beans should be up with all the rain we have had, and I plan on spraying them in 2 weeks.

Wonder if a lisence is needed to buy that stuff in Michigan, which I dont have. Been thinking about taking the test and learning about the other herbicdes other than Gylphosate.

I was looking at some on Agri-supply that claimed to have the surfactants included, for a pretty good price, but a lot of shipping. So I called the local farm supply stores and on the road to my farm I found some for $13.50 gal in 2 1/2 gal jugs, if it doesn't have surfactant I will get some, It's cheap ( I think)

You need to look at the label, most generics have a surfacant, a few do not. There are so many different generic names, hard to tell. You need to look at the label....

Are you using AIM or some other water treatment? Hard water does not work well with glyphosate, nor does 'dirty' water. It will bind up with clay or hard water particles & not soak into the plant. These types of products soften up your water in the tank. Granular ones are cheaper, liquid ones are easier to mix.

Here in Minnesota I've never used a herbicide that needs the certificate, but I've had the training & licence for 12 years or so now. It's a good idea. Look to learn a bit from it, rather than as a chore to do. Here anyhow they do pretty good telling you practical help on handling & mixing chemicals, they don't get hung up on boring lectures with no meaning.

Here you can use any chemical with 'caution' in the label, it's the more dangerous or more polluting one's that you actually need the training to buy.

No it is not. License isn't required for
Roundup anywhere, it is available in home centers and wouldn't be if it was restricted.

AND YES YOU SHOULD!!!!!! Lots to be learned as part of this.

Wasnt talking about roundup for the lisence but the reply about, Pronto "Big and Tuff"

rrlund · Jun 9, 2010

Don't let anybody B.S. you into thinking there's any difference. It all comes out of the same factory. The jugs and barrels are all filled with the same formula no matter what label is on them. That said,I use a surfactant called Corn Belt Guardian. Yes,it contains AMS.
If you aren't getting a good kill in quack grass,it's probably coming up from tillers below the ground before the glyphosate has a chance to get through the system. You'll no doubt have to let it get a little size to it and hit it a few times to get a good kill.

adding a surfactant to any roundup makes it work better. ask your chem dealer for his advice.
mine is call synergise

paul · Jun 9, 2010

Pronto is sold by Tractor Supply Co, and it is a generic glyphosate - it's a 41% Roundup is all.....

Quack grass is hard to kill with roundup. If you have a lot of quack you maybe should use a quart and a half. Add AMS to all herbicides you apply post-emerge if you have hard water, its cheap. As for surfactant read your label, most generics have it but not all. If its not in the mix you will get a poor kill. 10 GPA is on the low side for spring applied post-emerge herbicides, consider 15 to 20 GPA. With RR corn you should also be using a residual for later emerging weeds. I use reduced rates of Impact and Surpass tank-mixed with generic Gylphosate to control later emerging grass and broadleaf weeds.

Not that I care, but don't let everyone know you're using generic. I thought you were only supposed to use Roundup on RR crops so Monsanto can get more $$$.

8N'r--WI · Jun 9, 2010

Your comments bought a smile to my face....when I bought my "Round up Ready" seed (a whopping 3 full bags)I had to sign a form stating I would not use this seed to produce seed for sale that would compete with any Monsanto Brand...

I didn"t think my "large scale" ag practice would pose such a threat....:>)

You can most likely get 41% generic Gylphosate from you local ag chemical supplier cheaper than Pronto from TSC. Everything costs more at TSC!

OliverGuy · Jun 9, 2010

I had to sign it too. But you can guess what goes in my "fencerow" sprayer on my four wheeler and it works just fine. It does have the surfactant in it too. A long time ago my Dad used to put a squirt of dish soap in our small tanks to make the chemical "stick" better. Guess it helped.

MN Scott · Jun 9, 2010

Nope, only requirement with RR seed is you can't save crop for seed. You can spray it with whatever you want.

thurlow · Jun 9, 2010

Planted thousands and thousands of acres of RR soybeans; never signed anything. It was 'implied'. About the second year they were on the market, I was at the local CO-OP getting a couple of pallets of seed; a fellow with I was slightly acquainted (and whose son worked at the store) sidled up to me wanted to know if I would fill one of his grain trailers up if he left it in one of my fields at harvest time. He'd 'pay me for my trouble'. I just looked at him and always tried to steer clear of him afterwards.

You signed an agreement to not sell seed from your crop, not what kind of roundup you could use. They will throw the book at you if you get caught saving seed to replant or sell it to someone to plant.

>Everything costs more at TSC!

On the other side of the coin, you always save money because they never have in stock what you stopped to pickup.

evilboweivel · Jun 9, 2010

license is required for Roundup in a lot of applications in Ohio.
JUST BECAUSE YOU CAN BUY SOMETHING
DOSN'T MEAN YOU DON'T NEED TO BE LICENSED TO USE IT
ALL DEPENDS ON WHERE IT IS BEING USED

General rule is 17# of AMS per 100 gallons of water. Put it in the mix!!!
