Part 5 (Chapter 6) Introduction to Urban and Industrial Integrated Pest Management

Most nozzles on the hand-held sprayer offer a four-way multi-tip which can produce two [a] spray patterns and two [b] spray patterns.

The hand-held [a] sprayer is the most widely used piece of pesticide application equipment in the industry.

Equipment for applying pesticides can be placed into five general groups: 1) bait applicators; 2) [a] ; 3) [b]; 4) [c] and 5) [d] .

The amount of pressure that builds up in the tank is expressed as [a] or [b].

Sprayer pressure affects the amount of insecticide applied and the type of pesticide [a].

Droplets of 100 to 400 microns are classified as [a], while droplets larger than 400 microns are referred to as [b].

Lacquers are too [a] to be applied with standard nozzles and tips, and the use of [b] and hand-application is required.

The concept of ULD treatments using a [a] involves distributing a very small amount of concentrated insecticide solution over a relatively [b] area.

Droplets produced by cold foggers are in the 5 to 15 micron range and remain airborne for periods of [a] hours.

Generally, it is the size of the opening in the nozzle through which the liquid is forced which determines the insecticide [a] size.

Regarding backpack or knapsack sprayers,
a.)most professionals don't use tanks exceeding the 3-gal. capacity

b.)they are used for applying herbicides and insecticides to building perimeter

c.)most use specialized hand-operated levers

d.)they are the choice for precision applications using low pressures

To keep up-to-date on pest control equipment, the professional can:
a.)review current trade magazines

b.)review equipment information brochures

c.)talk with their suppliers

d.)attend educational conferences and seminars

Some important considerations when selecting the right pump for the job include
a.)the amount of pressure needed for the spraying operation

b.)if high pressure or larger volume applications will be made

c.)the LD50 of pesticides used

d.)the type of pesticide formulation that will be used in the sprayer

Foam applicators
a.)have been mostly used for termite control efforts in the past

b.)are available as handheld units for applying to hard-to-reach structural voids

c.)are not good for treating floor drains

d.)provide good residual coverage

If a compressed air sprayer is used daily, it should be cleaned thoroughly at least once a week. To clean the tank
a.)never use ammonia or other detergents to clean inside the tank

b.)scrub the outside of the tank with steel wool and detergent

c.)fill the tank with hot water and soak overnight

d.)rinse the tank thoroughly with clean water

A nozzle may be unclogged safely by
a.)using a soft bristle brush

b.)back-flushing with water

c.)using a knife

d.)cleaning the nozzle with a pin

Power sprayer nozzle performance depends on:
a.)nozzle design or type

b.)operating pressure

c.)size of the opening

d.)distance from nozzle to target

A power sprayer system can be broken down into five major components, including
a.)tank

b.)pump and motor

c.)shunt

d.)applicator or nozzle

Liquid insecticidal sprays are categorized according to the size of the particle that makes up the spray. Which of the following are correct?
a.)coarse spray = droplet size of 400 microns and larger

b.)mist aerosol = 100-400 microns

c.)fog aerosols = 50-100 microns

d.)vapors = less than 0.001 microns

Proper calibration of cold fogging equipment is critical because
a.)large droplets will settle out of the air too rapidly

b.)small droplets will be deflected around the target insect rather than hitting and sticking on it

c.)machines producing a visible fog create the potential for various hazards

d.)droplets may be too wet

Provides an even coat of spray on flat surfaces

Simple in form and function, but probably the most important piece of (ULD) equipment in the pest management industry

Pressurized aerosol containers

Distributing a very small amount of concentrated insecticide solution over a relatively large area

Unit of measure (1/1,000 of a millimeter) used to determine the diameter of spray droplets

List five safety considerations when using thermal foggers.

List six (6) helpful tips for the proper and safe use of cold fogging machines indoors.
