Determining Application Rate
Use the example results of the calculated speed,
spray width, and nozzle capacity to determine the
application rate.
Note:
The application rate may also be determined
by using the Nozzle Application Rate Tables (page
42), along with the chemical manufacturer's label of
recommendation.
The examples below are based on the following
information:
•
Average ground speed = 8.4 kph (5.2 mph)
•
Spray width = 2.7 m (108 inches)
•
Number of nozzles = 2
•
Nozzle capacity = 3.0 L/min (0.8 gpm)
Note:
The numbers 6 and 600 are constants used in
the formulas shown below.
Liter per 100 m 2
Single nozzle capacity (Lpm) x Number
of nozzles x 6
Speed (kph) x Spray width (m)
