1. Pesticide laws and regulations help to:
Protect the environment.
Knowing the proper procedures for diluting pesticide concentrates is:
An EPA general standard for certified applicators.
The format of pesticide labels is established by:
Knowing how to properly handle, mix, store, and dispose of pesticides is a requirement of the:
Environmental Protection Agency (EPA).
One purpose of federal pesticide regulations is to:
Prevent agricultural workers from handling pesticides or working in pesticide-treated areas.
State pesticide regulatory agencies generally have the responsibility for:
Certifying commercial pesticide applicators.
In addition to the actual pesticide label, which of the following is part of the pesticide labeling?
Worker Protection Standard provisions.
Which of the following is one of the require- ments for pesticide applicator certification?
Knowing how to use appropriate application methods for various pesticide formulations.
From the choices below, what pesticide use information found on a product label would be specific to an aerial application?
ASABE droplet size requirements.
Having a current Class II Medical Certificate is a requirement of the for all pilots making aerial pesticide applications.
Federal Aviation Agency (FAA).
The type of first aid given to a pesticide exposure victim depends on the:
Type of exposure
If a person shows signs of pesticide poisoning, he or she should:
Receive immediate medical attention.
If a person spills liquid pesticide onto his or her arm, the amount of exposure and injury can often be reduced by:
Washing the exposed area with soap and water.
During an application operation, pilots must wear the label-required personal protective equipment for pesticide handlers:
While making nozzle adjustments.
First-aid instructions to use for pesticide exposure is found on:
An up-to-date Standard Operating Procedures (SOP) document is useful to ground crew members especially when:
The communication channel with the pilot is lost.
For protection of the surrounding community, a good reason for securing pesticide applica- tion aircraft and other equipment when not in use is to:
Prevent intruder access to the equipment
At a minimum, the training that ground crews must receive as pesticide handlers is required to be performed:
Every five years, before performing handling activities.
Chances of pesticide exposure greatly increases if a pesticide handler fails to:
Wear the required personal protective equipment.
Good communication with the ground crew before and during an application operation may result in:
Fewer job delays.
Managing off-target pesticide drift during an aerial application is:
The pilot's responsibility.
Off-target pesticide drift is the offsite movement of the pesticide that occurs:
At the time of pesticide application or soon
The color code for a nozzle that produces spray droplets in the extra fine category is:
Generally, the optimum time for making an aerial application of a liquid when droplet evaporation is a concern is:
Which of the following factors has NO effect on off-target pesticide drift?
Constant 3 mph wind.
Wider-angle spray nozzles usually produce____________
droplets than narrower spray
The most effective boom lengths for reducing the amount of drift are:
75% of the wingspan or the rotor span.
Aside from external factors, the most important factors affecting off-target drift are:
The size of the spray droplets and the percentage of droplets within a certain size range.
Driftable fines are droplets in the size range of:
50 to 200 microns
The droplet size at which spray drift becomes a concern is:
200 microns and below.
Aircraft suitable for aerial application of pesticides must be:
Able to lift, transport, and disperse pesticides safely.
One of the reasons for an adequate vent in the aircraft pesticide tank is to:
Prevent a vacuum from altering the normal flow of liquid.
The purpose of baffles inside a liquid spray
tank is to:
Reduce sloshing of the liquid during flight.
Hydraulic agitation of the mixture in the aircraft spray tank requires:
Sufficient pump output capacity.
A proper functioning positive cutoff valve with a suck-back feature will supply ________________ pressure to the boom and nozzles when the spray flow is stopped.
The purpose of bleed valves at the ends of the spray boom is to:
Prevent pressure from building up from trapped air when the spray valve is opened.
To accommodate for the influence of prop wash on spray pattern, it is necessary to:
Reposition the nozzles on the spray boom.
The advantage of an electronic sprayer volume controller is that it:
Reduces or increases the spray output as airspeed changes.
Ram-air spreaders can:
Compromise fixed wing aircraft performance.
The purpose of adjusting ram-air spreader vanes is to:
Improve the granule distribution pattern.
The purpose of calibration is to:
Apply the correct amount of pesticide.
Applying a pesticide at a rate that is higher than the pesticide label rate is:
Increasing airspeed without changing the spray output will result in:
Less pesticide active ingredient applied per acre.
If 1700 ounces of material is collected from nozzles on a helicopter spray boom in 90 seconds, what is the total flow volume in gallons per minute?
An aircraft spraying system has an output volume of 8 gallons per minute. How many gallons are sprayed per mile when the aircraft travels at 130 miles per hour?
An effective swath width is the
Width of a single pass that includes portions of overlaps from other passes.
An aircraft sprays 20.2 gallons per minute. How many minutes of spraying time are needed to spray out 147 gallons of spray mixture?
Given an application rate of 11.3 gallons per acre, how many acres can be sprayed with 147 gallons of spray mixture?
If an aircraft treats 14 acres per tank of spray mixture, how many pints of pesticide liquid should be put into the spray tank to apply at a volume of 1.5 pints per acre?
How many acres are in a rectangular field that measures 620 feet by 1280 feet?
The last application flight of the day:
Requires the same attention as every other flight.
Varying the application speed without changing flow volume during an application will:
Result in uneven coverage.
The application pattern that helps to avoid flying through spray from a previous swath is the:
Race track pattern.
Ferrying flights must be made at an altitude of at least:
Ferrying flights that pass over areas where people live or work should:
Be varied by 1/8 to 1/4 mile for each trip.
Breaks seen in the normal cultivation patterns of a field may alert the pilot to:
Too wide or too narrow overlapping of spray passes will result in:
Uneven application patterns.
To avoid the adverse effect of headwinds or tailwinds on an application volume, you should fly:
Crosswind or 45 degrees to the crosswind.
Which of the following would have little effect on the safety and effectiveness of an application if changes occur during the operation?
Moving the operation to a different mixing- loading location.
The problem with flying too low when making a granule application is that:
Granules are still moving horizontally at lower heights.
