Round Up

Just wondering does round up get old and lose its power?

Stroby · Apr 10, 2017

Mine didn't, but, the weeds develop more resistance over time. It is best to "mix it rich" and get them the first time as to "mixing it light" and they then require even more spray to get them.

I haven't had an issue with the bulk containers going bad, but the stuff sold to the general public at Home Depot, lowes, etc loses its potency after while it seems. Changing application rates and mix can make up for loss of kill power.

This is general public stuff, I guess I will add more. Thanks

Wasn't there something when it first came out that you couldn't let it freeze? Maybe my memory is lost on that subject.

I never bring Roundup, 2,4d, etc. into the house to keep it from freezing. I just leave it out in the shed. Maybe it freezes, maybe it doesn't, but it is always good and effective the next year. Might take up to 3 years for me to use an entire jug.

The roundup Home Depot, Lowes, etc sells is so watered down it's almost ineffective.

I have always let leftover roundup set out in the shed. Always seemed to work the next spring.

Some chemicals are very sensitive to freezing.

Roundup isn't.

It is very remotely possible it may settle, and cause part of the jug/barrel to be water, and the other bottom part to be very heavy. If you don't
shake or circulate a bit, that could cause issues. This doesn't happen often with roundup, but could.

When I was a Commercial Applicator was told that any leftover thru the winter had to be agitated well .Always did,no problems

I keep it from freezing but only because i have a spot. I've gotten now to using more excitor with the roundup, if i want a better kill then adding extra roundup. i bought a jug of genartic roundup from the coop. my jug----$11.02 per gallon.

Read the label. It will have a shelf life date or prevent from freezing if it applies to the product.

I have a 17 year old jug of 41% ag strength. It still works like it did when new.
