    New in the business. Licensed and insured. Finally started spraying customers lawns this weekend.

    I made myself up a record sheet that is required in the manual.
    Requiring : name, address, temp, wind, pesticides used, EPA #, lot #, square ft treated, target pest, mechanical calibration (2 gallons/minute) and other stuff.

    My question: it asks for the dosage used

    IS that amount of gallons sprayed or the actual active chemical put on the lawn??

    example:
    the 2 1/2 gallon jug says: 1pound of chemical per gallon
    my sprayer calibration @ 2 gallons per 1000K

    i put 2.4 qts for acre = 86 gallons which equals .6 pounds of chemical per acre

    i spray a 10K yard = 20 gallons which is .1395 pounds of active chemical

    so i write down on "dosage used"=.14 pound

    Is this RIGHT?

    so

    I think you're trying to make it too hard for yourself. I don't think you need to worry about how much a.i. you are using. On 10k, you'll use 17.65 oz of chemical - that would be your dose.
