This will kill seeds, full grown trees, and any vegetation growing in the area or that has roots growing into the area. It also runs off with rain and will kill what it runs off to. 5-10 gallons per acre in a wetting spray.

What has worked well for me for total vegetation control is 10 lb Sahara DG, 2 quarts Garlon 4, and 1 quart Reward. This is not as likely to run off and kill things downstream, however it must not be used over the root zone of desirable trees.

On the jug label says 1 gallon w/25gal water covers 43,500 sqft. Wonder how much run off it will have at that rate.
I been reading everything I can't find the rate 1 gal per 25gal of water if there any run off due to rain ( online)

It works great, but like he's said it will run, just be careful.

According to the label, the lowest rate is 1 gallon per 10,000 sq ft. When doing a bare ground job, especially over a large area, consider the cost of an application failure or weed breakthrough. Who pays for you to re spray the area or take care of weeds that have popped up here and there? I do not mind an expensive spray mix if it means everything is dead and not going to come back for the rest of the year.

Pramitol runs no matter what rate you apply it at. Sadly, desirable trees and shrubs are more sensitive to it than the weeds. I also notice that grassy weeds are hard to control with it. That is where Sahara shines. If there is high grassy weed pressure, I add the maximum rate of oryzalin to the mix. However, this does not cover leguminous broadleaves and brush very well. Escort helps with that.

DuPont published some literature on bare ground weed control programs for various regions of the US. They do push their bare ground herbicides, however mention is made of other herbicides. Good take home points from the literature include knowing what kind of weeds are present, timing, and good application practices. It can be amazingly hard to provide total vegetation control. I think it is harder than weed control in lawns.

I wouldn't use it on a bank or hill. If you end up with a heavy rain within a few weeks after you will see damaged plants below

Yes seen that online but on the jug says something different .

The customer said the last guy used this few years ago with good results.
I told the customer hire that guy again .
They said he pass away.
All I know is what customer said how he applied it .He only applied the top side and let mother nature take care rest

I had one guy told me to mix half the rate with Gly4 blanket the area
He said, he had very little runoff but he is treating rock parking lots semi flat with grass borders with no kill of the grass.

I'll read more on stuff you posted to use maybe find something better and safer

I always hate trying new stuff

Dangerous. I would never apply something that ran on any kind of incline. A no runoff application would look like oryzalin or pendimethalin + Goal. Pick your postemergent combination depending on what has established there. Glyphosate is ok if there are no vines or brush.

I agree with green doc. I would not use pramitol on any kind of incline. Your are better off with a mix like was suggested above. It is way to mobile in the soil. I have seen large established trees get killed by a pramitol app that was done a significant distance away from the app site.
