Help with roundup mixing.

[ponytug]

Local Ag chemical supplier suggested 3 oz each of 41% glyphosate and triclopyr (Remedy) per gallon of water for a near total kill of all grass and brush. His large farmer brother recommended the same mix. Works very well for me. I have to be very careful around the cotton fields as triclopyr is deadly to cotton.

My experience with hard water and surfactant isn’t good. It immediately develops a milky scum on my 25 gal. tank strainer screen and clogs it. Southern Ag brand off Amazon.

​

What are you using for surfactant? SLS? Dawn?

Have you tried adding ammonium sulfate first?

All the best,

I buy the Roundup brand name and make about 4 gallons in a backpack sprayer.

There's your problem right there.
Don't buy Round Up~!!! You are paying a boatload for their advertising. Buy 51% Glyphosate in a 2.5 gallon container from Tractor Supply or other farm / ag supply house. You work out the math and you will kick yourself ten times for each time you bought the brand name.

Then mix it pursuant to the concentration you want (instructions on the container). Think of it like Liquor. If a little bit is good, more won't necessarily be better. Too much is not better.
It takes a few days to see the result (sometimes a week). To kill poison ivy, I use a machete on the vine and fill 'r up with glyphosate. You could use a little squirt of gasoline but it's prolly illegal.

I use a different (lighter) mix for the vegetable garden. Every single negative thing they (who ever "they" are) say about glyphosate is all made up hooey. Pure Bunko hooey. If ya want the research papers I can provide links.

Oh, clean your machete after chopping Poison ivy. I use Kero with a skosh of mineral oil mixed in.

never have used any of that.
Does it make it work better?

A couple of other things to keep in mind with Roundup (glyphosate)

The manufacturer has spent millions on research of how to use their products. The results of that research is on the label. Always read and follow the label. It will work best if you do.

Another interesting fact is that the 'Roundup Ready' gene used in soybeans and other crops comes from the Asian Jasmine vine. Asian Jasmine is often used in landscapes as a ground cover.

I looked again at the latest results and it’s pretty good, it appears it takes more than a week to work. I’d say using the ammonia sulfate and surfactant does help. It looks as if it worked on Mares Tail also but very slowly.

Sometimes slow is more thorough in that it results in total kill.

Tordon. But it’s restricted use, so it can only be bought by a licensed applicator.

That might be a state law thing

Amazon.com : tordon

I pour in equal parts Roundup or Glyphosate, 2,4D amine, Atrazine and add some surfactant and diesel fuel. If it's ditches I add Pramitol. I mix a gallon or so and pour it into my 40 gal sprayer. Results are fast and amazing.

your results may be equally amazing using just the diesel fuel and surfactant lol.

Could be. What I like about a little diesel fuel is you see the kill start the next day.
