well, i should have known better because when i calibrated on concrete i could clearly see it was to heavy on left and right. i blanket app'd my own yard with my backpack with spectracide weed stop (at the rate specified for bermuda grass on the label) sprayed at .5 gallons per 1,000 sq. ft. i walked to fast because i had a little bit left over, so was even less than .5 gallons per thousand. there is some yellowing in streaks that comfirms that its definetly comming out to heavy on right or left.. lol. unless i'm just overlapping to much.. i tried not to.. but that could be it. the yelowing is nothing that won't grow out in a week or 2, but definetly gotta get new tip. i ordered 8004, 8005, 8006 teejet xr tips, gonna keep trying. i don't wave back and forth, i hold it straight out infront.

i've never blanket app'd with a backpack before. only spot treatments when i worked for trugreen and a few other companies.

You can use painter's techinque, and cover the concrete more evenly by spraying in a series of overlapping figure 8 patterns as you walk forward.

It does not have to be perfect.

Do not use flat fan nozzles if you move your arm back and forth.
