How much Quinclorac 75 DF Herbicide do I use in a 4 gallon backpack sprayer?

My yard is 3400 sq ft.

Answer:

Quinclorac 75 DF is used at the rate of 0.367 oz per 1000 sq ft when applied as a broadcast appliation or spot treatment in a minimum of 0.5 gallons of water.  If you are just spot treating with a specific amount of water, for example 1 gallon, you would use the 1 tbsp per gallon of water. So if you are treating the entire lawn, you could use 1.25 oz in 4 gallons to treat the entire lawn.
