Spraying generic Roundup

I am about to spray 10-12 acres of former pasture ground with generic Roundup from the local fleet store. The label says its 41% Glyphosate. I will be spraying this with my ATV boomless Sprayer. My neighbor suggests adding some crop oil to the mix to help the product stick to the plants (weeds). I am wondering is crop oil a product name? or a generic terms for something else? Also is it really needed? The Glyphosate label doesn't mention needing crop oil. I'm just wondering if it is really needed, where I can get it and what do I ask for? Is Crop Oil restricted?
 
He's talking about a surfactant. It will actually end up costing you about as much per acre, as your glyphosate. I personally think it is a necessity. It does not require any license to purchase. Many people will tell you that dish soap, have the same affect. In large part they are correct. Palmolive, and dawn are the only two that I would consider. They have a neutral ionic factor. Most others do not. I wouldn't get excited about running out, and buying some. When you buy enough Palmolive to equal 2 1/2 gallons of surfactant, the surfactant will be cheaper.
 

Crop oil is a term for a spray adjuvant. Induce is one of several brands. It is used to help break the surface tension of the spray droplets when they hit the plant to give the chemical better coverage. It is not restricted and should be available where you purchase the chemical.
 
I just use more Roundup. Use 2 qts a acre. Will be just as cheap as throwing a bunch of stuff in the tank to (help) Vic

I wouldn't worry about it unless you have weeds with a waxy coating. I've heard diesel fuel will work as a poor farmer's surfactant.
 
The spray adjuctive will make a difference. It is your time and your dime. If you are unsure spray part of the field with and part of the field without.
 
As you can see, there are many opinions on this, many different ways. ;)

Mix the glyphosate on the heavy side of the label, and should be fine without. Most glyphosate has some form of surfactant in the jug already. What is the brand name of yours, we can look up the label? Sometimes the wrong 'crop oil' (there are three different types...) can argue with what is already in the jug and make things worse in the end....

What does help glyphosate a lot is some form of N in the water, only takes a little. AMS is granular like sugar, 40lb bag treats 300 gallon tank of spray. There are liquid versions too, many different names. It helps soften your water, glyphosate doesn't work well in hard water, and it helps the weeds grow a tad so they die better, is why you want to add some.

I have heard of others mixing 24D with glyphosate, but it used to be that didnt work - one kills the green part real fast, and the other kills the plant real slow by moving down to the root first. They would cancel each other out and not work near as good as either by the self. But, it must work as a lot do that.

It's been done every which way, it will work out for you however you try it.

I'd try to find a little AMS or liquid N to add, that does help condition the water so it all works better.

There's a surfacatant/water conditioner called Optima that I use. 2.5 gallons at 5 oz/acre will do about 60-65 acres. My records show it cost me $2.85 per acre this year. Jim
 
I have said this more then once, READ THE LABEL!!!!! It will tell you what you need to add or not to add, give you the rates to apply, and how to clean up your sprayer after the fact!

We can all tell you what has or hasn't worked for us, but YOU are the one that will be held accountable, should you have any misapplication, or problems with your sprayer.

I just can't stress enough how important knowing and understanding the label is.
 
We use a generic round up. The label says not to add a surfactant.

The product you bought should have a label. As our ag agent says, the companies that make these chemicals spend millions figuring out the correct application methods. Follow them.
 
I added some Ammonium Sulfate as per the label and sprayed it today. I could see the spray sticking to the leaves really well. In a week we shall see how many spots I missed, lol.

Thanks for the advice.
