Section 14: Application Technology

Question 1

List 7 factors to consider when selecting application equipment.

Answer 1

Type of application
Application location
Pesticide formulation
Environmental conditions
Size, shape, and topography of the application site
Target site or pest
Available application time

Question 2

What type of application equipment provides an uneven application?

Answer 2

Trigger pump sprayers
Granular equipment on a sloping ground

Question 3

What type of application equipment uses concentrated pesticides with no liquid carrier?

Answer 3

Ultra low volume equipment (ULV)

Question 4

What does it mean to calibrate pesticide application equipment?

Answer 4

Checking and adjusting the application rate of the equipment under typical operational conditions and includes a test of each nozzle.
Prior to use the sprayer must be calibrated to deliver the correct amount of pesticide, in a uniform distribution, on a specific area.

Question 5

What can be the result if pesticide application equipment is not calibrated properly?

Answer 5

The application rate may be too high or too low and non uniform distribution.

Over application results in: increased application costs, damage to application site, damage to the environment, increased applicator or bystander exposure, excessive pesticide residues.

Under application results in: poor control of the pest, need to retreat the area, development of resistant pests

Question 6

Where can you find information on calibration procedures for your equipment?

Answer 6

Equipment manual, equipment dealers, industry specialist

Question 7

State 3 reasons why proper preventative maintenance of application equipment is important.

Answer 7

Reduce accidents which can be hazardous to your personal safety
Preven spills which may contaminate the environment
Prevent damage to non- target sites
Minimize breakdowns which cost you time and money
Increase service life of your equipment
Ensure that the correct application rate was uniformly applied.
