Michael,

No matter what type of sprayer you are using, to assure the best reach and coverage, your sprayer should be calibrated.  Calibrating the sprayer will assure the best overall coverage and minimize A handheld sprayer, backpack sprayer or small capacity sprayers can be calibrated in generally the same manner.  If you are using a hand held wand, you can follow these procedures:   
Calibrate hand-held sprayers by 1) spraying a known area using water, 2) measuring the amount of water applied, and 3) calculating the number of gallons applied per acre (gpa). For example, 1.5 gallons on 1,000 sq. ft. is the same as 65 gallons per acre. 

          (43,560 sq. ft. per acre / 1,000 sq. ft.) x 1.5 gallon = 65 gpa. 

The desired rate in lb/A or pt/A or oz/A is used to calculate the amount of product to add to the spray solution. For example, If 3 pt/A is desired: 

          3 pt/A / 65 gpa = 0.046 pt. or 0.74 fl. Oz. or 
          1.5 tablespoons per gallon of spray solution 
          (16 fl. oz. = 1 pt.; 2 tablespoons = 1 fl. Oz.). 

When calibration of a hand-held sprayer is not possible and the product used is safe to the environment and non-target plants, a volume of 
50 to 70 gpa can be assumed. However, the actual volume applied can vary considerably with the type of sprayer, spray pressure and technique of the applicator, so calibration is strongly encouraged.
