Help with roundup mixing.

Try emailing the researcher.

Never friggin dawned on me. Thx

In general, soil itself acts as a filter. Like most filters, it can only handle a fixed volume at a time.

in Civil engineering not too long ago the mantra was:
"The solution to pollution is dilution."
My granddaughter is in Purdue Civil Engineering I should ask her if they still think that way.

I suppose I could ask my son. He has an MS in ChemE. He did his thesis on using switchgrass for biofuels, but he works in a papermill. Part of his job is environmental controls and monitoring.

As I expected, he had more questions than answers...soil type, weather, etc. Biggest risk would be in heavy clay soil with heavy rain right after. He did say that it would require an EPA report if 50 gallons or more are 'spilled'.

I did some estimates...to spray my entire driveway it would be something less than 20 gallons. (that's how many gallons it would take to paint a wall the size of my driveway...cannot imagine having to put the diesel on that thick. Given where we are, there are probably a lot more things that get to the groundwater than a little diesel fuel. There is brown coal nearby. Imagine every time it rains, the water soaks through that coal on its way to the water table. I would probably just use the herbicide myself, but I think panic over the use of diesel that way is a bit of Chicken Little syndrome.

I used to work at a medical school, and they said that when I questioned dumping radioactive tracers down the sink. The translation was, "We don't want to deal with safe disposal and they will never catch us."

So what is a good available substitute for Ortho Triox?

I maintain a commercial parking lot in industrial zone and one Triox in the cracks and crevices and good...

Now it is every 4 to 6 weeks roundup and string trimmer...

Jeez guys, I put maybe a cup or two in a 40 gallon mix. That's sprayed maybe 2 times a year. I doubt that any ever hits the ground considering how heavy the vegetation is but if it did it would take 1000 years to get 50 gallons on the ground. Good Lord....

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.

You can leave the 2,4-D, atrazine and diesel out of this mix and get the same result. Diesel will instantly burn the leaves of the plant, and will not allow the Roundup and 2,4-D to be taken into the plant.

Atrazine mostly works as a pre-emergent and so does Pramitol. Pramitol is more of a soil sterilant and will kill/prevent more plants than the Atrazine. Pramitil does basically the same thing that Atrazine does, and more.

Roundup is much safer to apply than diesel.

I work with lots of high school athletic programs and there are still a few that use diesel to mark the lines on their football fields.

Thanks for the great information you have shared. What is the best way to control an early infestation of Johnson grass?

 

[workinonit]

I understand what you are saying but on several points I have to disagree. I have used this mixture with great results for years, much better results than Roundup alone. Much better. It kills faster and lasts mutiple times longer. As far as atrazine goes, prior to Roundup ready corn seed we used almost exclusively atrazine as a pre and post emergent herbicide. We sprayed in pre-emergent and mixed it with the nitrogen post-emergent. I've been using a broadcast mix of atrazine and 2,4D amine for years over my turf grass to control early season weeds and primarily sand spurs. I mix it with my Reagent when I spray for fire ants. I use it in my total kill mixture because I have it. As for Pramitol, yes it is a ground sterilant and again I mix it with my total kill because I have it and I hope some of it makes it's way to the soil. With these mixes I usually end up only having to spray each once per year vs mutiple times of spraying with just Roundup. Thanks for your recommendations CTC.
