How much 4 speed to a gallon of water?
When using herbicides such as 4 Speed XT, the amount of water is dependent on the how much water it takes to cover a 1,000 sq ft area. The best way to gauge this is by marking off a 10ft by 100ft area. Fill your pump sprayer and "mock" spray the area thoroughly. This will tell you how much water to mix the 4 Speed XT with.
