NYS PCO NYS PCO Equipment and Calibration

Question 1

Calibration of pesticide application equipment is performed to ensure that:

Accepted Answer

The correct amount of pesticide is applied per unit area as specified on the label

Answer

Calibration verifies that the sprayer delivers the label-specified application rate per acre or square foot, preventing under- or over-application.

Question 2

A power sprayer nozzle that produces a fan pattern is MOST appropriate for which type of application?

Accepted Answer

Flat-fan nozzles for broadcast or band spraying on flat surfaces

Answer

Flat-fan nozzles produce an even, flat spray pattern ideal for broadcast coverage of horizontal surfaces.

Question 3

If a sprayer is applying too much pesticide per 1,000 sq ft, the PCO should:

Accepted Answer

Increase walking speed, decrease pressure, or switch to a nozzle with lower output

Answer

Reducing output per area requires increasing walking speed, reducing nozzle pressure, or using a lower-output nozzle to bring the application rate into label compliance.

Question 4

What does GPM stand for in pesticide sprayer calibration?

Accepted Answer

Gallons Per Minute

Answer

GPM (gallons per minute) is the nozzle output flow rate used as a key variable in calculating the correct application rate during calibration.

Question 5

Which piece of equipment is used to measure nozzle output during sprayer calibration?

Accepted Answer

A graduated cylinder or collection container timed over 30–60 seconds

Answer

Collecting and measuring nozzle output in a graduated cylinder for a timed interval determines actual GPM, which is the basis for calibration calculations.
