The Herbiculator can’t run on this device

This browser is too old to load the calculator, so nothing below would work. Rather than leave you with a blank screen in the field, here’s what to try:

Update your browser, or update the device’s software.
Try Chrome, Firefox, or Safari if you’re using something else.

The Herbiculator didn’t load

Your device is fine — the app’s files didn’t arrive. That’s usually signal. Once it has loaded properly the app is stored on the device and works with no signal at all.

Move somewhere with better reception and tap Try again.
If you’re on mobile data, check it isn’t turned off for Chrome.

Accurate mixes,
no maths

Pick a volume, pick a mix, and The Herbiculator tells you exactly how much of everything goes in the tank. No mental arithmetic over an open drum.

Any recipe,
any vessel

Set the volume and every amount follows — the same mix in a knapsack, a unit on the ute, or whatever else you’re filling.

Keep your
go-to mixes

Save a recipe mix and it’s there for next time. The ones you use most are a tap away, scaled to whatever you’re filling today.

Products you use,
with their rates

The common ones are already in there. Add what’s missing, set the rates you actually mix at, and they’re a tap away from then on.

Labels and SDS,
before you pour

Check the Safety Data Sheet for PPE, or the label itself, straight from the app. Links can point at your own sources.

This app is
in beta

This app is still being built. If something’s missing, something’s broken, or it’s just working nicely — I’d love to hear it (you can reach me through 'Contact' via settings).

Free whilst in beta.
