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.
Enter treated area, carrier gallons, and at least one product rate. The mix updates as you type.
01Start 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.
02Compatibility 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.
