Every premix conversion is computed from lb ai per gallon on the label — never a guessed ratio. Two independent calculation paths must agree before a number is shown.
Built for the field
Every tool works one-handed on a phone from the cab, the shop, or the field edge. No login, no install, no waiting on a rep to call back.
Evidence you can check
Answers cite their sources — the label passage, the trial guide, the chemistry. TANKWISE assists your judgment; it never asks you to replace it.
“I built TANKWISE after years of answering these questions from a pickup with a phone and three PDFs. It gets you to the right number and the right label passage faster — without replacing the label or your judgment.”

Where does the data come from?
Product chemistry comes from federally approved EPA labels — 10,112 pages indexed across 462 products. Weed control ratings come from university trial guides (NDSU and K-State). Rotation rules are cross-referenced against the label for every product shown.
Does it replace the product label?
No, and it never will. TANKWISE is a decision-support reference that gets you to the right number and the right label passage faster. Always read and follow the approved product label — rates and uses vary by state and crop stage.
Does it work on a phone in the field?
That's what it was built for. Every tool works one-handed on a phone — from the cab, the shop, or the field edge.
How do I get help or suggest a product?
Reach out through the contact page — questions, missing products, and corrections are all welcome. It's built by one weed scientist who reads every message.
