Tank mix calculator for lawn care

A tank mix plan should calculate amounts, respect labels, check compatibility, and leave a record of what went into the sprayer.

Calculate tank mix amounts

Enter product rates per 1,000 sq ft. Units can be oz, fl oz, lb, or mL as long as each rate uses the same unit you want in the result.

Start with the label

Extension pesticide safety guidance is consistent: the label controls use. If the label prohibits a mixture, rate, turf species, site, or condition, the calculator does not make it safe.

Compatibility matters

Montana State Extension and Nebraska Extension both describe jar tests as a way to check physical compatibility before mixing pesticides at tank scale. This is especially important when labels do not provide clear tank-mix instructions or when water quality may affect the mix.

What Lawn Dominator helps track

  • Products and rates by lawn size.
  • Carrier volume and spray notes.
  • Weather and timing conditions.
  • Application history for follow-up decisions.
