Chemical mix ratios can easily be adjusted in
between or lower than the listed 0-7 settings by
pre-diluting your concentrate.
For example, if you wish to spray at .5 oz/gal, simply
mix your chemical 50:50 with clean water before
placing it in the concentrate tank.
Divide the desired rate by the closest higher rate
(oz. /gal) value from above guide to determine the %
of chemical in concentrate tank.
