1A APPLICATORS EXAM QUESTIONS
AND ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT RATED A+
Are most perennial weeds best managed using herbicides?
✔✔ False — While herbicides can help, many perennial weeds require a
combination of control strategies for effective long-term management.
Do symptoms of soil-applied photosynthesis-inhibiting herbicides usually
appear first on the roots?
✔✔ False — These symptoms typically show up on the leaves or above-ground
parts of the plant, not the roots.
You sprayed 1/8 acre and had to refill your tank with 4 1/8 gallons of water.
What is your application rate?
✔✔ 33 GPA (Gallons Per Acre) — This is the correct calculation based on the
spray volume used over 1/8 acre.
Are crop rotation and using narrow row spacing examples of cultural pest
control methods?
✔✔ True — Both practices help reduce pest pressure by disrupting pest life cycles
or improving crop competition.
Do Triazine herbicides tend to persist longer in acidic (low pH) soils?
✔✔ False — They are actually more likely to carry over in alkaline (high pH)
soils.
ACCase-inhibiting herbicides such as sethoxydim are primarily root inhibitors.
True
False - ANSWER✔✔False
,Sulfonylurea herbicides inhibit amino acid synthesis.
True
False - ANSWER✔✔True
Herbicides are more likely to leach into groundwater when applied to sandy soils
than soils with high organic matter?
True
False - ANSWER✔✔True
Glyphosate is an example of a plant growth regulator?
True
False - ANSWER✔✔False
Soil-applied herbicides are only translocated in the photosynthetic stream
(Phloem).
True
False - ANSWER✔✔False
White leaves (bleaching) are a symptom of pigment inhibitors?
True
, False - ANSWER✔✔True
Air temperature can affect vapor drift.
True
False - ANSWER✔✔True
A sandy soil with 2 percent organic matter would typically require a higher rate of
soil applied herbicides than a clay loam soil with 5 percent organic matter.
True
False - ANSWER✔✔False
Most annual weeds germinate in the upper 1/2 inch of the soil.
True
False - ANSWER✔✔True
Contact herbicides require better spray coverage that translocated herbicides.
True
False - ANSWER✔✔True
Pesticides that are listed ad 1.5 EC and 90 DF contain:
