I just got my applicator's license here in Oklahoma and need help on what pre-post emergents to apply (on bermuda). I have a yellow 25 gallon PK sprayer (from Atwoods) to work with this first go round until I get my new 200 gallon skid in a month or so. My 25 gallon sprayer has about 30' of 3/8 air hose and a wand attached that resembles one you would see at a car wash. The pump is just a little electric one that came on it that has the aligator clamps that clip on the battery. I bought it last year to spray roundup with.
