In order to calibrate the field application rate of your sprayer applicator, you have sprayed a mile strip at a speed of 10 km/h with water prior to adding the herbicide to the tank. According to your application calculations, you should use 275 litres to spray this area.
In order to refill the sprayer to the starting level, you added 250 litres of water.
How would you adjust the speed of your applicator in order to apply the correct rate of herbicide?
.Rate of application changes directly with speed.
In order to increase the application rate to the desired level the speed of the applicator must be reduced. All other things remaining the same, if you travel slower you increase the application rate. (If you travel 20% slower you will apply 20% more spray solution.)
Test application rate = 250 litres
Test applicator speed = 10 km/h
Desired application rate = 275 litres
250 ÷ 275 = 0.91
0.91 x 10 = 9.1 km/h
The correct travel speed for this application will be a speed of 9.1 km/h.
You are applying Target to a field of wheat. When you ran a field calibration test, you applied 52 L/acre at a pressure setting of 250 kPa. The desired application rate is 45 L/acre.
How would you adjust the pressure in order to apply the correct rate?
Present application rate 52 L/acre
Present pressure 250 kPa
Desired application rate 45 L/acre
The formula for this calculation is:
New Pressure (kPa) =
Desired Application Rate (L/ha)2 x Present Pressure (kPa)
Present Application Rate (L/ha)
452 × 250 = 187 kPa
52
In order to reduce the application rate, the pressure must be reduced to 190 kPa.
Additional note: The recommended pressure range for Target is 200 - 300 kPa. As the new pressure rate is outside this range some other manner must be used to adjust the application rate. Options include increasing ground speed or changing nozzles.
If you are applying 45 L/ acre, the forward speed is approximately 8 km/h and the nozzle spacing is 50 cm. What nozzle capacity (L/minute) do you require?
The formula for nozzle capacity is:
Litres/minute
= L/acre x km/h × cm
24,300
= 45 × 8 × 50
24,300
= 0.74
The nozzle required for this application would be capable of applying 0.74 minute
If a sprayer has a tank capacity of 2500 litres and you want to apply 50 L/acre, how many acres can you treat with one tank load?
- 2500 liters ÷ 50 L/acre = 50 acres
If the field to be treated in question 4 was being treated with Liberty, how much Liberty should be added to one tank load?
- The application rate for Liberty is 1.35 L/acre: The tank will cover 50 acres. Therefore 50 × 1.35 = 67.50 liters of Liberty go into one tankful
If the field to be treated in question 4 was being treated with Everest for green foxtail, how much Everest should be added to one tank load?
- The application rate for Everest is 8.7g/acre. The tank will cover 50 acres. Therefore 50 × 8.7g/acre = 435 g of Everest go into one tankful.
List four (4) ways to minimize spray drift.
- spray under favorable weather conditions -
- choose suitable application equipment -
-operate the application equipment correctly

Non-uniform application can result from variations in
a.
b.
c.
a. granule flow rates
b. forward speed
c. discharge height of the applicator
When should granular application equipment be calibrated?
When it is new
-when the output of the system changes
- when travel speed, metering mechanism, weather conditions, or the pesticide is changed
How would you verify the application output of an individual outlet on a pneumatic granular applicator?
Do an application test run with nylon “bags” fitted to catch the output at all of the individual applicator outlets. By accurately weighing the amount of granules collected at each outlet you can verify the output of each individual outlet.
During a calibration test, you used an applicator with a 15 meter boom and travelled for 100 meters. How many hectares were covered in this test? How many acres?
1 hectare = 10,000 square meters
1 hectare = 2.47 acres
The area covered in this test would be;
15 meters × 100 meters = 1,500 square meters
As one hectare is 10,000 square meters
The test area is 1,500 / 10,000 = .15 hectare
Each hectare is equal to 2.47 acres
The test area would be .15 × 2.47 = .37 acre
In the test outlined in question 4. you collected 2.66 kg of product from the outlets on the boom. What would your application rate be in kg/acre?
.If you collected 2.66 kg on .37 acre then the application
rate would be 2.66 kg x (1 / .37 acre) =
7.19 kg/acre
What effect can high winds have on a granular herbicide application?
High winds cause distortions in the distribution pattern of the granules which results in poor herbicide performance.
List two (2) types of blockage of the feeder system of a granular applicator?
The feeder system can be blocked be a lump or foreign material in the flow line. Examples would be pieces of bag or lumps in the granule supply. Another way is if the granules bridge over the feeder mechanism. This can occur under high humidity or if the applicator has sat for a while and the granules have caked or hardened in place.
Before using the granular applicator after extended storage, always make sure that none of the moving parts are:
Seized from corrosion
Why is it important to follow up on complaints quickly?
It indicates willingness to accept responsibility. You may be able to limit future damage if you determine the cause of the customer’s damage

- acknowledge the farmer’s concerns - visit the field
- ask the manufacturer’s representative to visit the field
- discuss the situation with the manufacturer’s representative prior to meeting with the customer
- accompany the manufacturer’s representative to the field - try and remain neutral
