TEXAS PESTICIDE APPLICATOR GENERAL STANDARDS EXAM
PREP: 200 COMPREHENSIVE QUESTIONS WITH VERIFIED
ANSWERS AND IN-DEPTH RATIONALES COVERING FIFRA, WPS,
IPM, CALIBRATION, LABELING, PPE, TOXICOLOGY, AND STATE
REGULATIONS
1. Which federal act governs the registration, labeling, and
distribution of pesticide products in the United States?
A) Toxic Substances Control Act (TSCA)
B) Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C) Clean Water Act (CWA)
D) Occupational Safety and Health Act (OSHA)
Correct Answer: B) Federal Insecticide, Fungicide, and Rodenticide Act
(FIFRA)
Rationale: FIFRA is the primary federal law that gives the EPA authority
to register pesticides and enforce label compliance.
2. Under Texas law, which agency issues pesticide applicator licenses
and enforces state pesticide regulations?
A) Texas Commission on Environmental Quality (TCEQ)
B) Texas Department of Agriculture (TDA)
C) Texas Department of State Health Services (DSHS)
D) Texas Parks and Wildlife Department (TPWD)
Correct Answer: B) Texas Department of Agriculture (TDA)
Rationale: The TDA administers the Texas Pesticide Applicator Licensing
Program and sets state-specific rules.
,3. Which type of sprayer is more likely to cause you to injure sensitive
vegetation or wildlife by overdosing with concentrated pesticides?
A) Boom sprayer
B) Hand sprayer
C) ULV sprayer
D) Airblast sprayer
Correct Answer: C) ULV sprayer
Rationale: ULV (Ultra-Low Volume) sprayers apply highly concentrated
pesticides, increasing the risk of overdose injury to sensitive vegetation
or wildlife.
4. You must increase pressure ___ times to double flow rate.
A) 2
B) 3
C) 4
D) 5
Correct Answer: C) 4
Rationale: To double the flow rate from a nozzle, pressure must be
increased four times. Flow rate is proportional to the square root of
pressure.
5. List 3 materials that nozzles are made from. (Select the correct
combination)
A) Brass, plastic, and aluminum
B) Brass, plastic, and stainless steel
C) Brass, stainless steel, and titanium
D) Plastic, stainless steel, and copper
Correct Answer: B) Brass, plastic, and stainless steel
Rationale: Common nozzle materials include brass, plastic, stainless
,steel, ceramic, and hardened stainless steel. Brass, plastic, and stainless
steel are three correct examples.
6. True or False: Among nozzle materials, brass is the least resistant to
wear.
A) True
B) False
Correct Answer: A) True
Rationale: Brass is the softest and least wear-resistant among common
nozzle materials, wearing faster than stainless steel, ceramic, or
hardened stainless steel.
7. Which pump does not have an automatic pressure relief
characteristic?
A) Centrifugal pump
B) Roller pump
C) Piston pump
D) Gear pump
Correct Answer: C) Piston pump
Rationale: Piston pumps do not have automatic pressure relief; they
require a separate pressure relief valve to prevent over-pressurization.
8. List 2 advantages and 1 disadvantage of a piston pump. Which
option correctly identifies them?
A) Advantages: No leakage inside pump chamber, output unaffected by
pressure; Disadvantage: Expensive
B) Advantages: No leakage inside pump chamber, output unaffected by
pressure; Disadvantage: Poor maneuverability
C) Advantages: Self-priming, high pressure; Disadvantage: Heavy
D) Advantages: Low cost, simple design; Disadvantage: Leaks
, Correct Answer: B) Advantages: No leakage inside pump chamber,
output unaffected by pressure; Disadvantage: Poor maneuverability
Rationale: Piston pumps have no internal leakage and output is virtually
unaffected by pressure, but they are less maneuverable.
9. What are some basic functions of spray nozzles?
A) Regulate flow and atomize liquid only
B) Atomize liquid and spread droplets only
C) Regulate flow, atomize liquid, and spread droplets in a specific
pattern
D) Regulate flow and filter liquid only
Correct Answer: C) Regulate flow, atomize liquid, and spread droplets
in a specific pattern
Rationale: The three basic functions of spray nozzles are regulating
liquid flow, atomizing the liquid stream, and spreading droplets in a
specific pattern.
10. Worn nozzle tips produce poor spray patterns and ___ flow rates
than new nozzles.
A) lower
B) higher
C) the same
D) unpredictable
Correct Answer: B) higher
Rationale: Worn nozzle tips allow more liquid to pass through, resulting
in higher flow rates than new nozzles.
11. You should replace a used nozzle when its flow rate varies ___ % or
more from a new nozzle.
A) 3
