ILLINOIS PESTICIDE APPLICATOR LATEST EXAMS
TEST PAPER QUESTIONS AND ANSWERS SURE A+
✔✔vegetative reproductive structures - ✔✔rhizomes, budding roots, or tubers
✔✔contact pesticides - ✔✔control by direct contact with the pest
✔✔pesticide resistance - ✔✔develops when a few individuals in a pest population
survive a pesticide treatment because of their slightly different genetic makeup
-then reproduction and pass resistance to offspring
✔✔spot applications - ✔✔treat only a portion of the total area and are used to control
pests that are grouped or clustered
✔✔band applications - ✔✔treat only a narrow strip over or alongside a row of desirable
plants
✔✔broadcast applications - ✔✔treat the entire area or field
✔✔overlap - ✔✔the portion of a spray pattern or spreader pattern that applies over the
adjoining pattern to improve uniformity
-expressed as percentage of the application pattern or swath
, ✔✔effective swath width - ✔✔the distance each successive swath should offset in order
to allow the edges of neighboring swaths to overlap
✔✔application rate - ✔✔the amount of material applied per unit treated
✔✔carrier - ✔✔the material into which the pesticides are mixed for applications
-usually water
✔✔Hydraulic agitation - ✔✔A mixing method in which some solution circulates through
the pump and back into the tank
✔✔mechanical agitation - ✔✔uses paddles to mix instead of hydraulics
✔✔pressure drop - ✔✔a long hose or a small hose restricts flow and will cause reduced
pressure at its end
✔✔flat fan pattern - ✔✔a thin sheet of spray produced by a flat fan nozzle
✔✔even flat fan - ✔✔pattern is a thin sheet of spray with uniform spray deposits across
the spray pattern
✔✔hollow cone pattern - ✔✔Spray Deposited in a circle with no droplets in the center.
✔✔full cone pattern - ✔✔deposits spray in a circle with droplets throughout the circle
and are also avalaible in a variety of spray angles
✔✔spray quality/ droplet spectrum - ✔✔describe the range in droplet size that a spray
nozzle produces and is important for an effective spray application
✔✔calibration - ✔✔involves selecting the right sized orifice (nozzle size) and operating
pressure
-also observe pattern of overlap
✔✔GPA - ✔✔Gallons per acre
✔✔GPM - ✔✔Flow rate per nozzle, in gallons per minute
✔✔MPH - ✔✔application speed, in miles per hour
✔✔W - ✔✔effective sprayed width per nozzle, in inches
✔✔GPA= - ✔✔GPM X 5940 / MPH X W
✔✔Hopper - ✔✔holds the granules until they are spread
