AHAS Inhibitors - (ANSWER)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 - (ANSWER)manually operated switch----deployed where two circuits meet or circuit
portion from an energized feeder
-not designed to auto interrupt electrical load or be used as line protection from overload, short circuit
or fault
Allelopathy - (ANSWER)ability of some plants including certain grasses, to release chems that suppress
other plant species growing around them
ALS Inhibitors - (ANSWER)chemical class of commonly used IVM herbicides in which the mode of action
inhibits a key enzyme
-acetolactate synthase
Alternating Current(AC) - (ANSWER)electric current that reverses its direction many times per second at
regular intervals typically used in power supplies
Aluminum Conductor Steel-Reinforced Cable(ACSR) - (ANSWER)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

-ANSI A300(Part 7) - (ANSWER)American National Standard for Tree Care Operations----
Tree/Shrub/Wood Plant Maintenance
-IVM---utility ROW
ANSI Z133 - (ANSWER)ANSI Arboricultural Operations----Safety Reqs
-safety standard of practice for tree care
Approach Distance - (ANSWER)minimum distance that must be kept btwn conductors/energized
equipment & qualified line clearance personnel & non-qualified & bodies/tools
-approach distance vary w qualifications of personnel & voltages
Automatic Line Recloser - (ANSWER)circuit breaker equipped w mechanism that auto close the breaker
after it has been opened due to a. fault
-designed to reset quickly to give the cause of a fault opp to clear
-may immediately recharge the circuit several times at adjustable time delay----2/3 operations within
seconds before they open permanently

development of plants
-produced at sites where cells are dividing primarily in the shoot tips
-auxin like compounds may be produced synthetically
Auxin Transport Inhibitors - (ANSWER)class of selective herbicides that disrupt auxin transport
-auxin transport obstruction causes unnatural concentration of auxin in meristematic shoots & roots,
disturbing the auxin tolerances req for normal plant growth
