    Um, are you certified to spray these product?

    The question you are asking is basic stuff that an applicator should know.

    To answer your question....

    If your tank is 100 gallons, and you are spraying 1.25 gallons/1000 sq/ft then your tank can spray a max of 80,000 sq/ft.

    If you wish to apply 1.8 oz of SpeedZone/1000 sq/ft then you will need to multiply your rate by the area you wish to treat. In your case 1.8 * 80 for 144 oz.

    Use the same method for calculating your Pre-m.

    If you are not certified to use these products then do the wise thing and contact it out.

    Total gallons (100) divided by spray rate (1.25 gal.) times mix rate (1.8 & 1.3)

    100/1.25 = 80
    80 x 1.8 = 144
    80 x 1.3 = 104
