After I mix 2 gallons of Sedgehammer, how long will it remain effective?

I have my nutsedge down to a small area with only a dozen colonies so I mix 2 gallons and fill a one quart spray bottle for convenience. How long will the remaining liquid product remain effective?


Typically it is not recommended to leave any pesticide solution in a sprayer for more than two weeks at a time.  You should only mix what you plan on using.  If you want to leave the product in the sprayer for longer you should at least shake and agitate the sprayer every few days to keep the solution from separating.
