SPRAYER CALIBRATION, ADJUSTMENT, AND OPERATION (continued)
operating at the correct speed, we can be sure that you’ll be traveling at the right
speed, as well.
c. With the machine traveling in HIGH gear at full throttle, use a stopwatch or wristwatch
to measure and record the time required to travel the 143-foot (44 meter) turf course.
The normal time is approximately 20 seconds.
d. EXAMPLE: It took 20 seconds to travel 143 feet.
e. Find the row in Table 2 that matches your measured time above.
2. Determine the product Label Rate, in ounces, required to treat 1000 square feet by
locating that information on the Product label. If the label only lists pints per acre or quarts
per acre you must convert that to ounces per 1000 square feet by using one of the
following formulas
a. Label lists only pints per acre.
a. Multiply the number of pints by 16 to get ounces per acre.
b. Divide number of ounces per acre by 43.56
c. EXAMPLE: Apply 3 pints per acre. 3 x 16 = 48 ounces per acre. 48 / 43.56 =
1.1 ounce per thousand square feet.
b. Label lists only quarts per acre.
d. Multiply the number of quarts by 32 to get ounces per acre.
e. Divide number of ounces per acre by 43.56
f. EXAMPLE: Apply 1.5 quarts per acre. 1.5 x 32 = 48 ounces per acre. 48 /
43.56 = 1.1 ounce per thousand square feet.
3. Find the column in Table 2 that matches the label rate in ounces per thousand above
and read down to the time row from step 1. The box at the intersection of your time
row and ounce per thousand column contains the number ounces needed to mix 1
gallon of spray solution.
a. Referring to our EXAMPLES: The intersection of row 20 and column 1.1 is
4.69.
b. 4.69 ounces of product is needed to make 1 gallon of spray.
