=
✔✔Where would you look to find out whether a pesticide is classified as Restricted
Use? - ✔✔If a pesticide is classified as restricted use, the words "Restricted Use
Pesticide" will appear on the front panel of the pesticide label.
✔✔Match the signal words and symbols you may see on a pesticide product with the
appropriate meaning.
Caution _______
Danger________
Warning ______
Poison and the skull and crossbones [symbol]_______
a. Highly toxic
b. Moderately toxic
c. Highly toxic as a poison, rather than as a skin or eye irritant
d. Slightly toxic or relatively nontoxic - ✔✔Caution - D
Danger - A
Warning - B
Poison - C
✔✔Can you use the signal word on a pesticide label to judge the likelihood of suffering
acute, delayed or allergic effects if you are overexposed to the product? Explain. -
✔✔Signal words and symbols indicate the likelihood that you will experience acute
harmful effects if you are overexposed. Signal words do not tell you any thing about the
risks of delayed harmful effects or allergic effects.
✔✔What types of hazard statements are on pesticide labeling? - ✔✔You should look for
precautions about hazards to humans (and domestic animals), environmental hazards
and physical/chemical hazards.
✔✔The EPA registration number refers to the facility where the pesticide product was
made. (True or False?) - ✔✔False
✔✔A pesticide use bulletin for protection of endangered species may contain limitations
on certain pesticide applications in an area where an endangered species habitat exists.
(True or False?) - ✔✔True
✔✔It is adequate to orally warn agricultural workers of an application of VIP Pest-No if
the locations are explained. (True or False?) - ✔✔False. This product label requires the
entrances to treated areas to also be posted.
, ✔✔Point-source pollution - ✔✔Point-source pollution comes from a specific, identifiable
place (point).
✔✔Nonpoint-source pollution - ✔✔Nonpoint-source pollution comes from a wide area.
The movement of pesticides into streams after broadcast applications is an example of
nonpoint-source pollution.
✔✔Which types of nozzles lower the risk of pesticide air drift? - ✔✔High-pressure and
fine nozzles produce very small spray droplets that are very likely to drift. Lower
pressure and coarse nozzles produce larger droplets with less drift potential. Pesticides
will vary in their potential to drift.
✔✔What is volatization? - ✔✔Volatilization occurs when a solid or liquid turns into a
gas. A pesticide in a gaseous state can be carried away from a treated area by air
currents; movement of pesticide vapors is called vapor drift. Unlike the drift of sprays
and dusts that can sometimes be seen during an application, vapor drift is invisible.
Volatilization of pesticides increases with higher air temperature and air movement,
higher temperature at the treated surface (soil, plant, etc.), low relative humidity and
decreasing size of droplets.
✔✔Adsorption - ✔✔Adsorption is the binding of chemicals to soil particles.
Pesticides that are strongly adsorbed (bound) are less likely to be carried from the
treated area by surface water or to leach through the soil; they may, however, be moved
readily by soil erosion.
✔✔Absorption - ✔✔Absorption is the process by which chemicals are taken up by
plants and other organisms.
✔✔Microbial Degradation - ✔✔Microbial degradation occurs when microorganisms such
as fungi and bacteria break down pesticides and use them as a food source.
Most microbial activity occurs in the top 12 inches of soil.
The chemical structure of the pesticide also influences the ability of microorganisms to
break it down. In particular, compounds with chlorine in their structures resist
degradation and can persist in the environment for a long time.
This can be avoided or delayed by alternating types of pesticides used, spot-treating
and applying pesticides only when needed.
✔✔Chemical Degradation - ✔✔Chemical degradation of a pesticide involves reactions
that change its chemical bonds, reducing the pesticide's original structure into less
complex components.
