8-54. Equipment Availability and Suitability<br />
a. The requirements for pest control equipment<br />
are numerous because of the variety of<br />
organisms, their habitat, and the types of control<br />
agents that are to be dispersed. Depending on the<br />
control problem, pesticide dispersal equipment is<br />
available for meeting the needs of confined or<br />
broad areas, whether the requirements call for<br />
stationary, portable, vehicular, or aerial equipment<br />
use. Because equipment types are continually<br />
being modified or developed to meet specialized<br />
or changing needs, it is essential to contact the<br />
appropriate medical entomologist or applied biologist<br />
for recommendations regarding the most<br />
appropriate equipment, as well as its authorized<br />
use.<br />
b. Article 8-11, Pesticide Formulation and<br />
Dispersal, discusses formulations of pesticides,<br />
i.e., emulsions, suspensions, granules, etc., and<br />
types of pesticide dispersal, i.e., gases, aerosols,<br />
sprays, etc. Table 8-2 is provided for quick reference<br />
(see next page for table) on equipment<br />
types, formulations applicable, and best scenarios<br />
for use. Additional information regarding the use<br />
of equipment in the application of specific<br />
formulations, types of dispersal equipment,<br />
accessory platforms – vehicles or aircraft –<br />
required for transportation, advantages and<br />
disadvantages of each is discussed in this section.<br />
c. There are several factors used in determining<br />
which spray system will be used for a spray<br />
mission. The target area to be sprayed, its size,<br />
location, habitat, and accessibility are considered<br />
when determining which spray equipment should<br />
be used. The size of the area will determine how<br />
quickly it can be sprayed, if it can be achieved on<br />
foot, or if it requires ground transportation. The<br />
location may be adjacent to an environmentally<br />
protected area, requiring greater drift control that<br />
may eliminate the use of aerial spray application.<br />
If the habitat has thick vegetation, ULV penetration<br />
will be greatly reduced, thus making a<br />
residual treatment more effective. The target area<br />
may not be accessible by road or it may contain<br />
numerous flooded acres that cannot be penetrated<br />
by ground vehicles, thereby necessi-tating the use<br />
of aerial or manual sprayers. The availability and<br />
schedule of the required vehicle or aircraft is<br />
another important factor. For example, mosquito<br />
control is generally most effective from dusk to<br />
several hours after dark. If the desired vehicle or<br />
aircraft is available for spray missions at different<br />
times, vector control effectiveness will be greatly<br />
reduced, possibly necessitating alternative<br />
application methods.<br />
