Just go ahead and use it.It might be a little weaker,but i doubt it.If mixed with water and stored it will breakdown.

Larry is right about chemicals breaking down, some chemicals do not like alkaline water they prefer water with a lower ph. I learned this at an ag meeting this spring. I used to drain the sprayer of glyphosate and store it, found out that it no killing power after it sits even a few hours the chemical "cracks". The expert told us to test the well with ph tests strips that you can buy for testing pool water for about 5 bucks a pack, that way you know more about the water source that you are spraying with. He said if you mix a load of chemical, go spray it before it breaks down because of water ph that is incompatible. Don't park the sprayer because you need a sandwich or it got too windy....plan ahead.

Larry is right. I have used old 2,4-D that I have gotten from old farm auctions, on my hay fields. It still works, to a varying degree. One thing, with 2, 4-D, always store it away from other types of chemicals, in hot weather, it can migrate in vapor form, into other chemicals, unnoticed, till your insecticide, for example, starts damaging your roses. I always store 2, 4-D with other like chemicals, like banvel, 3way, trimec, trichlopyr, etc.

I found some last year that I bought back in the early 90's. It worked fine.

I never buy more than a one gallon container of 2,4 d at a time 'cause I don't need to, but more often than not that partially used gallon sets out in the old wash house through at least one winter, and I've never noticed that any potency was lost.

I buy it in quarts so that I don't have to renew my applicator's license and pay the fee. Bein retired, that doesn't make sense. Anyhew, I leave it in the original sealed containers on the shelf in my shop (not temp controlled) till ready to use and only mix what I plan to spray. I mix it by hose pressure as I add the water (sprayer is 100 gal and no agitator) and go to the field immediately pumping all of it out and flushing my equipment.
I don't feel that I have an age problem with it's performance. I don't think I'd mix it and keep it as I don't want to corrode up my equipment if for no other reason.

This is the first I heard of storing 2-4-D away from other chemicals. I have always stored it in the original container next to my other chemicals I use around the farm. I never had a problem doing so that I am aware of. Guess I better check with my supplier.
I think your 2-4-D will be fine. I haven't done it lately but I have used it after sitting around and even getting exposed to cold weather. It seem to work OK. I normal keep it where it is not exposed to freezing temps though.

Low temperature should have no affect. As for storage around other chemicals, here is some detail:
"2,4-D should be stored in a cool, dry, well-ventilated area in tightly sealed containers that are labeled in accordance with OSHA's Hazard Communication Standard [29 CFR 1910.1200]. Containers of 2,4-D should be protected from physical damage and should be stored separately from strong oxidizers such as chlorine, bromine, and fluorine. "
I hope this helps a bit.
