Name some of the things that affect the efficacy of a pesticide application. - CORRECT ANSWERS
The effects of a pesticide application depend on a number of things . Some important factors are proper
timing (to treat susceptible pest stages), favorable treatment conditions (temperature, humidity,
moisture, time of day, and plant condition), and thorough coverage. Pesticides must be delivered to the
target at the correct rate to do their job.
What are some things to consider before choosing a piece of application equipment? - CORRECT
ANSWERS When evaluating equipment, ask yourself these questions:
- Is the equipment well suited for the target(s) you need to treat?
- Will it apply the formulation(s) you wish to use?
- Is it affordable?
- Is it sturdy and durable enough to do the job?
- Is it easy to fill, operate, and clean?
- Will it apply pesticides in an environmentally sound manner?
What are some advantages and disadvantages of spray applications? - CORRECT ANSWERS
Most spray applications use water as a carrier. Many types of spray equipment are on the market.
However, some pesticide formulations cannot be applied as a spray. Others must be agitated to keep
insoluble particles from settling. Liquid spray particles can drift if not managed properly.
Name the major parts of a spraying system. - CORRECT ANSWERS The common
components of any spraying system are a holding tank, a nozzle (or several nozzles), a hose or tube (or
system of hoses) connecting the tank with the nozzle(s), and the device or system that provides
pressure. In addition, some sprayers have a way to agitate the spray mixture.
, Why is sprayer configuration (set-up) important? - CORRECT ANSWERS A
sprayer must be configured properly (and used correctly) to produce a uniform application.
Describe the function of the spray tank. - CORRECT ANSWERS The tank holds
the mixed liquid pesticide.
How should you care for a spray tank? - CORRECT ANSWERS To keep tanks in
good condition, handle them with care. Careful handling and proper storage can help to prevent cracks
and leaks. Keep spray tanks clean. Debris from a dirty tank may block narrow passages in hoses or tubes,
screens, and nozzles. Contaminants may affect a spray solution, resulting in incompatibility or
phytotoxicity. For example, herbicide residue from a previous application in a tank may harm the plants
an insecticide or fungicide application is supposed to protect. For that reason, plant health managers
should have at least two spraying systems - one dedicated to herbicides and another for applying
fungicides and/or insecticides.
What do the hoses do? - CORRECT ANSWERS Hoses carry the liquid from the
tank to the nozzle. Like all sprayer components, they should be chemical-resistant. This will prevent
them from swelling or breaking down when exposed to organic solvents like those found in many liquid
pesticide formulations. Check them on a regular basis, to be sure there are no cracks or leaks.
What is the function of the nozzle? - CORRECT ANSWERS Pressure forces the
spray liquid through one or more nozzles. The shape and size of the nozzle orifice affects the flow rate
and the spray pattern. Nozzles are made for many different spraying requirements. Manufacturers of
sprayer nozzle tips supply data sheets for the delivery rate (usually in gallons per minute within a range
of pressures) and pattern. However, these specification sheets cannot give the actual application rate.
This is because application rate is also dependent on speed and pressure.
Why is it a good idea to have some sort of filter or screen in your spraying system? - CORRECT ANSWERS
Filters or screens will trap particles. Particles in the system can cause problems by plugging hoses and
damaging the pump. Proper use of filters protects the working parts of the sprayer and reduces nozzle
wear.
