How much Pramaxis MEC Plant Growth Regulator is needed per gallon of water to treat St. Augustine turfgrass? I am using a 3 gallon sprayer.


The usage rate for Pramaxis MEC Plant Growth Regulator will depend the type of area for the application. For residential and commercial turf, the mix rate is 0.10 to 0.15 fl oz per 1000 sq ft. You will need to determine if 1 gallon of water is enough to thoroughly cover a 1000 sq ft area as water is acting as the carrier to get the active ingredient into the lawn. Please view the recommended Rate Chart on page 6 of the product label for more information.
