Q4 Plus Turf Herbicide can be applied using a hose end sprayer for spot treatments only at the rate of 3 oz per gallon of water. You may however have more accuracy with the backpack sprayer when using as a broadcast application as the rate is not set per gallon of water but per area. Please follow the product label for application.
