Section 8: Application Equipment Flashcards
(25 cards)
What are the two most common equipment types used to apply pesticides?
The two most common equipment types are sprayers and spreaders.
What is broadcast treatment?
Broadcast treatment is an application method where pesticides are spread uniformly over a large area.
What is spot treatment?
Spot treatment is an application method targeting specific areas or spots where pests are present.
What is space treatment?
Space treatment is an application method used to control pests in a specific volume of air or space.
How do you identify the appropriate equipment type to use given a product label?
You identify the appropriate equipment type by reviewing the product label for recommended application methods and equipment.
What is the purpose of application equipment calibration?
The purpose of application equipment calibration is to ensure accurate delivery of pesticides at the correct rate.
List three equipment-related factors that affect application rate.
Three factors are nozzle size, pressure, and speed of application.
Where are leaks likely to develop on application equipment?
Leaks are likely to develop at hose connections, fittings, and seals.
How is nozzle wear determined?
Nozzle wear is determined by checking for changes in spray pattern and flow rate.
How do you decide if a nozzle needs to be replaced?
A nozzle needs to be replaced if it shows significant wear or if the spray pattern is inconsistent.
How do you calculate the area of a rectangle?
The area of a rectangle is calculated by multiplying its length by its width.
How do you calculate the area of a circle?
The area of a circle is calculated using the formula πr², where r is the radius.
How do you calculate the volume of a cube?
The volume of a cube is calculated by raising the length of one side to the third power (s³).
How do you convert units of liquid measure?
Units of liquid measure can be converted using a conversion chart.
How do you convert units of dry measure?
Units of dry measure can be converted using a conversion chart.
How do you convert units of linear measure?
Units of linear measure can be converted using a conversion chart.
How do you convert units of area measure?
Units of area measure can be converted using a conversion chart.
How do you calculate how much product is needed given a label application rate and total area?
Multiply the label application rate by the total area to determine the amount of product needed.
How do you calculate how much product is needed to mix a full tank?
Multiply the label application rate by the tank size to determine the amount of product needed.
How do you determine if the equipment is delivering the proper amount during a calibration trial?
Compare the amount of material applied during the trial to the label application rate.
List three common equipment-related factors to monitor during application.
Three factors to monitor are pressure, flow rate, and nozzle condition.
How do you visually check equipment to ensure the calibrated application rate remains the same?
Visually check for consistent spray patterns and flow rates during operation.
Why is it important to clean out application equipment between jobs?
Cleaning out application equipment prevents contamination and ensures proper functioning.
What are proper site characteristics to clean equipment?
Proper site characteristics include a designated wash area away from water sources and drainage.
