Every tank, mixed right the first time.
Lawn size, tank size, carrier volume, and whatever's going in. We split the job across tanks and tell you exactly what to pour into each one — in the order it goes in.

Rates start at the label default. Change any of them — the tank recalculates as you type.

30,000 ft² at 1 gal per thousand needs 30.0 gal of finished spray — 1 full tank plus a 10.0 gal finish tank.

Rates here are label ranges, not permission. The label on your jug wins every time — read it, and follow the one in your state.
Written for the guy standing next to the tank.
We split it across tanks
A 4-gallon backpack doesn't do 30,000 ft² in one pass. You get tank one, tank two, and a short last tank measured for exactly the area that's left.
Numbered, in pour order
Dry formulations first, then liquids, surfactant last. Dump a WDG into a tank that already has oil in it and you'll be cleaning a screen instead of spraying.
Calibrate in five minutes
Spray water on a measured patch, tell us what it took, and we'll give you your real gal/1,000, GPA, walking speed, and acres per hour.
We flag it, loudly
Over the maximum rate, missing a required surfactant, a tank too loaded with dry solids to stay in solution — all of it turns red before you pour.
