QUESTIONS WITH VERIFIED ANSWERS |LATEST UPDATE
What types of hazard statements are on pesticide labeling? - Correct answer -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?)
- Correct answer -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?) - Correct answer -
True
It is adequate to orally warn agricultural workers of an application of VIP Pest-No if the locations are
explained. (True or False?) - Correct answer -False. This product label requires the entrances to treated
areas to also be posted.
Point-source pollution - Correct answer -Point-source pollution comes from a specific, identifiable place
(point).
1|Page
,Nonpoint-source pollution - Correct answer -Nonpoint-source pollution comes from a wide area. The
movement of pesticides into streams after broadcast applications is an example of nonpoint-source
pollution.
MSDS - Correct answer -Material Safety Data Sheets
Explain the differences between the terms "label" and "labeling." - Correct answer -The label is the
information printed on or attached to the pesticide container.
Labeling includes the label itself, plus all other information you receive from the manufacturer about the
product when you buy it.
Where would you look to find out whether a pesticide is classified as Restricted Use? - Correct answer -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 - Correct answer -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. - Correct answer -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.
Which types of nozzles lower the risk of pesticide air drift? - Correct answer -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? - Correct answer -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 - Correct answer -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 - Correct answer -Absorption is the process by which chemicals are taken up by plants and
other organisms.
Microbial Degradation - Correct answer -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.
