    I mixed a quad sprayer load of round up bio (90L) but due to the non stop rain i never got my spraying done my question is does the round up go off or would it be effective in the spring?

    Not sure if you had it mixed with water happened me some years back and clumps of brown stuff was at the bottom of the tank that could block the filter but it should still work I would think.
    At this stage you have no choice but to spray it out in spring and wash out gotten of tank anyway then it will either work or it won't you will know a few weeks after spraying.

    If you're going to keep it in the sprayer protect well from frost because roundup freezes at +4 degrees.

    Heard of undiluted beet spray that froze during the big freeze a few yrs back wiping out a whole field of beet when it was used the following year. Freezing altered its chemistry and turned it into roundup!

    It definitely raises the freezing point of water.

    I had roundup left from last year. It worked perfect this year. It did block up the small holes on my weed kicker though. If I was filling it again I'd be sure to filter it first. Didnt notice any decline in the quality. I stored it in 20 litre drums though.
