CAT 3 PESTICIDE CERTIFICATION PRACTICE
EXAM 2026 QUESTIONS WITH ACCURATE
ANSWERS
◉ Filter Strips and Vegetation Buffers. Answer: Untreated grass
strips next to streams, ponds, and other sensitive areas that can trap
much of the pesticide running off treated sites.
◉ Depth to Groundwater. Answer: The distance from the soil surface
down to the water table.
◉ Backflow. Answer: When the water source filling the pesticide
application equipment has a water pressure drop unexpectedly in
the supply line, electricity is shut down or a pump fails and the
pesticide runs back into the water source, contaminating it.
◉ Reduced Pressure Principal Device. Answer: Two independent
check valves in the water supply line, with an automatic pressure
differential valve located between the two valves.
◉ Pressurized Vacuum Breaker. Answer: Vees stop backflow in the
waterline is under continuous water pressure and the waterline
pressure is lost.
,◉ Atmospheric Vacuum Breaker. Answer: These let air from the
atmosphere into the waterline to break the backflow siphon at the
event of pressure loss in the waterline.
◉ Chemigation. Answer: Application of pesticides and fertilizers
through irrigation systems
◉ Pesticide Waste. Answer: Includes both pesticides that you cannot
use as originally intended, old pesticides that may no longer be
effective or pesticides you no longer need or want.
◉ Waste Pesticides. Answer: Pesticides that are no longer usable or
wanted.
Examples-
The government has banned the use of the pesticide.
The pesticide has been stored too long and lost effectiveness or
changed in other ways so it no longer works.
The pesticide is left over or you no longer need or want it.
◉ Incident Response Plan. Answer: This plan helps you prepare for
and deal with pesticide and or fertilizer incident quickly and
effectively. The plan should contain at least the following
information;
An emergency response contact list
, Product labels and product material safety data sheet (MSDS)
First aide information
Prefire planning
Maps
Use and handling procedures
Emergency equipment and supplies for pesticide and fertilizer
incidents
Release procedures
Anhydrous Ammonia (NH3) equipment and procedures
Employee release response training
Date last revised or updated
◉ Agricultural Chemicals. Answer: Substances such as pesticides,
herbicides, and fertilizers
◉ STARR. Answer: Secure - Key people/children/pet/animals away
from site and wear PPE
Telephone - if there is a threat to public safety call 911 and or fire
department if needed. Then call safety duty officer to report
Abate - Control the source of contamination and contain the
contamination so it does not spread any further
Recover - collect the released chemical and any contaminated soil or
other materials
