Does Round Up really loose strength if kept in the sprayer more than 24 hours?

    I read this in the Round Up instruction book. I mix 2 oz./gal along with 3 oz of Sythe, and so far haven't noticed a problem with reduced effectiveness if I don't use up the whole mix for 2-3 days. Has anyone else had a problem, or is this just a possibility they have to inform you about?

    I use Round Up dry packs. One dry pack, 4oz scythe, and a dab of spreader sticker to a gallon of water. It always works and I've never had a clog.

    You want to make sure you put roundup 1st than add scythe, and make sure to mix will not gel. If you put scythe 1st it will gel.
