How long can mixed herbicides last

[woodlandfarms]

So I am spraying crossbow on our pile of noxious blackberries. I mixed up 25 gallons and had a breakdown. In the 24 hours waiting for the part the weather has changed. I now have rain for the rest of the week so this mix will sit for 6 days probably. Thoughts?

Assuming you have a spray wand, recirculate the tank contents before your next application. The label may well recommend a shorter time limit for application after mixing, but you don't have much to lose by using what you have already mixed.

You’ll be fine. Crossbow equivalents I keep in a five gallon hand pump sprayer all spring and summer for small touch ups.

For blackberries it helps to add a surfactant. Spraying in the fall is best.

I've had glyphosate mixes form like strings in it, but probably not in only 6 days.

I am stirring every day so so far so good.. no gelling yet.
