To calculate actual application rate (litres per hectare), use
the following formula:
Application Rate (L/ha) =
Total sprayer output (L/min)
x 600 ÷ speed (Km/hr) ÷ row spacing (m)
÷ number rows in one pass
Example 1
(as per Tier 1 example)
22.8 (L/min) x 600
÷ 7.5km/hr ÷ 3m (row spacing)
÷ 2 (rows/pass)
= 304 litres/ha
Example 2
(as per Tier 2 example)
33.7 (L/min) x 600
÷ 7.5 km/hr ÷ 3m (row spacing)
÷ 2 (rows/pass)
= 449 litres/ha.
STEP 9 - IF THE TESTED RATE IS
UNSATISFACTORY
If your tested application rate does not meet your
requirements, your options are:
A) In Auto mode - if application rate is not
being achieved:
• Operating pressure will climb if nozzles are too small
or blocked or speed is too fast.
Likewise, if your pressure filter is blocked (even
partially), you may experience excessive pressure at
the pump.
Make adjustments accordingly.
• Operating pressure will fall if nozzles are too large or
speed is too slow. Make adjustments accordingly.
B) In Manual mode - the Controller application
rate can be altered by:
• Adjusting pressure up or down to increase or decrease
rate of application (use +/- keys).
• Adjusting spraying speed up or down to decrease or
increase rate of application.
• Changing to a different nozzle capacity.
Repeat necessary testing procedures and calculation of
application rate if adjustments or changes are made
LITRES PER 100 METRES / ROW
Many Auto Rate controllers, including the Fusion controller
have an option for Litres per 100 metres and is occasionally
the unit of preference in some vineyard operations. It’s a
simpler formula as row width is not relevant.
The calculation requires volume and distance, such as 11 litres
per 100 metres (of rows). The operator only needs to follow the
chemical label rate for mixing concentrate per 100 L.
