QUESTIONS AND
CORRECT VERIFIED ANSWERS 2026/2027
latest
Aerial Application - ANS✔✔-VM application of herbicide using
aircraft(helicopters/fixed wing)
Aerial LIft - ANS✔✔-truck, logging skidder or vehicle mounted w
hydraulic boom supported bucket or semi-enclosed working platform
used to elevate workers
AHAS Inhibitors - ANS✔✔-chemical class of commonly IVM
herbicides in which the mode of action inhibits key botanical enzyme
-acetohdroxycacid synthase(AHAS)--- biosynthesis of critical amino
acids
Airbrake Switch - ANS✔✔-manually operated switch----deployed
where two circuits meet or circuit portion from an energized feeder
Page | 1
,- not designed to auto interrupt electrical load or be used as line
protection from overload, short circuit or fault
Allelopathy - ANS✔✔-ability of some plants including certain
grasses, to release chems that suppress other plant species growing
around them
Accident - ANS✔✔-discredited term for unplanned, undesirable
event that could result in unintentional injury/property damage
attributed to fate/bad luck
Accident Pyramid - ANS✔✔-illustration of Herbert Heinrich
principles of accident prevention ---- bottom has thousands of unsafe
acts/conditions, led to 300 close calls, 29 minor injuries & ultimately
one major fatality/injury at top
Accrual Accounting - ANS✔✔-accounting methodology that records
revenues & costs when they occur
ACSR - ANS✔✔-aluminum conductor steel reinforced
Page | 2
,Action Threshold - ANS✔✔-point at which the level of incompatible
plant species, density, height, location, condition threatens the stated
management objectives & requires implementation of control method
Active Listening - ANS✔✔-structured face to face communication
technique that improves performance & increases understanding
btwn people
- use persons name
-paraphrase their message
Acute Toxicity - ANS✔✔-adverse effects resulting from exposure to
a single dose or exposure to multiple doses of a substance over short
time frame
ALS Inhibitors - ANS✔✔-chemical class of commonly used IVM
herbicides in which the mode of action inhibits a key enzyme
-acetolactate synthase
Page | 3
, Alternating Current(AC) - ANS✔✔-electric current that reverses its
direction many times per second at regular intervals typically used in
power supplies
Aluminum Conductor Steel-Reinforced Cable(ACSR) - ANS✔✔-
energize cable constructed from aluminum wire stranded around a
steel core
- lightweight, low cost
- tendency to stretch when heated----high electrical load or high
temp
- to minimize stretch/add strength --- steel core is added
Ampere(amp, A) - ANS✔✔-measure of current
- 1 A = charge carried by 6.25 x 10^18 electrons moving past a
given point in one second
- ANSI A300(Part 7) - ANS✔✔-American National Standard for
Tree Care Operations---Tree/Shrub/Wood Plant Maintenance
-IVM --utility ROW
