You should only dilute the amount of Precor IGR Concentrate that you plan to spray within about 24 hours. You do not want to leave product inside a sprayer after diluting it. You can choose to mix 1/2 oz of Precor IGR with 1/2 gal of water if you are only going to use that much product per treatment.
