Calibration of Boomless/Clusterjet Nozzle Sprayers:

• Fill spray tank with water to a marked level
• Drive in a straight line for 660 feet, operating the sprayer at a constant pressure and speed.
• Refill the tank to the original level to determine the numer of gallons used.
• Measure the width (ft.) of the area sprayed.
• Calculate as follows:
  (gallons used x 66) / width of sprayed area (feet) = gallons sprayed per acre
  tank capacity(gallons)/gallons sprayed per acre = acres sprayed per tank
• Add the appropriate amount of herbicide to the tank and fill.

• Record the time required to travel 100 feet under spraying conditions.
• Record the number of ounces sprayed from one nozzle for the length of time required to drive 100 feet.
• Calculate as follows:
  (40 x ounces sprayed) = nozzle spacing (inches)
  tank capacity(gallons)/gallons sprayed per acre = acres sprayed per tank
• Add the appropriate amount of herbicide to the tank and fill.

• Conventional basal:
  Apply diesel fuel oil, kerosene or a herbicide/diesel fuel oil mixture (2 to 4 percent herbicide) to the lower 12 to 18 inches of the trunk of a brush plant. The solution is applied completely around the trunk with sufficient volume to allow runoff and puddling a the soil surface.
• Low-volume basal:
  Apply a mixture containing diesel fuel oil plus 15 to 25 percent herbicide, or diesel fuel oil plus 15 to 25 percent herbicide to wet the lower 12 to 18 inches of the trunk completely around, but not to the point of runoff.
• Streamline basal:
  Apply a mixture containing diesel fuel oil plus 15 to 25 percent herbicide, or diesel fuel oil plus 15 to 25 percent herbicide and 10 percent penetrant, in a band (3 to 4 inches wide) completely around the trunk near ground level.

• 1 to 2 qts. per 100 gals. water
• 2 to 4 tsps. per gal. water

• 8 feet + 1 foot per mph of wind expected.
