Ounce Method
1. Determine how long it takes to cover the test strip. Use the following
chart to determine the length of your test strip. Row width for broadcast
application is equal to your nozzle spacing. For your drop nozzle or
band application, use row spacing.
Row width or nozzle spacing (in.)
2. Measure the amount of time it takes you to travel the test strip when
throttle is set at spraying speed.
3. In a container (with oz. measurements), catch the spray from one nozzle
for that amount of time. For drop or band nozzles, catch the spray from
all nozzles for the row.
4. Read the ounces in the container. That is the actual U.S. GPA applied.
(ounces = GPA)
