glyphosate and 24D mix Expiration?

[RadarTech]

Well, I am surprised by this… I was cleaning out the back of the shop, and found a 30 gallon sprayer tank and it was tagged glyphosate mixed with 24D and water 40, 40, 20.. it is about 3/4 full..
now the date on that sharpied tag was 2022..

and frankly I don’t even think that date is right, because I distinctly remember mixing it and using it and I thought I drained it last spring….


But here we are…

So my questions—

it isn’t gelled or lumpy…
1. do you think it is still usable?
2. Do you think with tank neutralizer that tank will be usable for anything else again?

If it will spray and doesn’t have lumps, give it a try. Worst that can happen is it doesn’t kill your weeds.

Yea. I am also wondering if the tank could ever be neutralized…

I’m gonna do something unique to spray … I have a hitch packer we sometimes use when going to the beach…
I’m gonna throw it on the 3PH Reese hitch and put the tank on that..
then I can use the cabbed tractor…..

I was using the UTV.. but it does not have heat or air.. ;-)

I think a tank neutralizer is worth a try. Or just use the sprayer for weed killer. I have 3 sprayers: weed killer, insecticide, and liquid fertilizer. That way you don’t need to neutralize the tanks, just rinse them after use.

mix glyphosate and 24D in several 2.5 gallon jugs to use in hand sprayer. some in the 2 year old range when I use them. work just as good as ones mixed recently.

Any rubber hose would need to be replaced. It takes a molecule of 2,4D to screw up certain plants. Cotton is super sensitive... The tank should be able to be cleaned.

Pretty sure it's still usable as a weed killer.

I've recently used some trimec and others from 10 - 15 years old or so. Weeds still died

My Grandfather taught me to not mix tanks. He had a small orchard (maybe 12 trees) of dwarf apples in Essex Jct. Vt. It was several years old and had just started producing. Then he sprayed one year with a pump that had some residue in it and wiped out the orchard.

The spray mix will do just as good as if you mixed it yesterday most likely, and on the farm we spray everything out of the same 500 gallon sprayer and have for years without any issues of any kind, If you have any doubts try a test area. Good luck.

In my 25 gallon sprayer, I have switched from roundup on the gravel driveway to 2-4D for dandelions in the yard by simply spraying half a tank of straight water through the sprayer after spraying roundup. I never had any problems.

....I never had any problems.

Problem would happen if you were to use the tank AFTER spraying 2,4D (you clean like you normally would) then use the sprayer on a sensitive crop like like cotton. You *might* get it clean enough but it takes just molecules of 2,4D to screw up some plants.

If you are using the tank to kill one thing vs. killing another thing - you don't even need to clean it. I guess the OP needs to state what else his plans are for the tank...

Grass can handle 2,4D google says the normal rate for 2,4D on perennial grasses; "Use 2 to 4.2 pints of product per acre per application". That's why you never had a problem.

I'm guessing most of us just use the tanks for killing only... the research station I worked at had separate sprayers for 2,4D since they killed thousands of dollars of research plots one year.

Glyphosate (Roundup) will kill most actively growing plants, so good cleaning after that chemical is important if you want to spray 2-4-D on the lawn to kill broadleaf weeds.

I agree with you somewhat but I was assuming, a near empty tank after RoundUp would only leave a trace amount of it. After you refill the tank with water for a 2,4D spray, that trace amount would not effectively hurt a thing. Now the (full strength) residue left in the spray boom, that is another story!!! Yes, clean the tank....

Agree. Just a triple rinse and flushing the boom would be sufficient.
