2024 ACTUAL EXAM 200 QUESTIONS AND
CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) |ALREADY GRADED A+
first step in weed control - ANSWER >>>identification of weed
broadleaf weeds - ANSWER >>>netted veins
narrowleaf weeds (grasses) - ANSWER >>>long, thin leaves with
parallel veins
areas preferred by annuals - ANSWER >>>soil is disturbed or
perennial plants are spotty/poor
areas preferred by winter annuals - ANSWER >>>soil is disturbed in
fall or left exposed over winter
areas preferred by biennials - ANSWER >>>areas not mowed or
disturbed
areas preferred by perennials - ANSWER >>>areas with minimal soil
disturbance
Examples foxtail, crabgrass, common chickweed, henbit - ANSWER
>>>annuals weeds
Examples garlic mustard, wild carrot, bull thistle, common teasel -
ANSWER >>>Biennial Weeds
,Examples Johnsongrass, dandelion, Canada Thistle, honeysuckle -
ANSWER >>>Perennial Weeds
Herbaceous perennial - ANSWER >>>die in fall, but root systems
overwinter
woody perennial - ANSWER >>>persistent aboveground stems that
remain each season
monocotyledons (monocots) - ANSWER >>>parallel-veined leaves
that are much longer than they are wide; grasses or grasslike
dicotyledons (dicots) - ANSWER >>>netted-veins that are usually less
elongated than grass; broadleaves
vegetative characteristics used to identify grass weeds - ANSWER
>>>collar region, ligule, stem shape, nodes, presence of hair
vegetative characteristics used to identify broadleaf weeds - ANSWER
>>>cotyledons, leaves, flowers, fruits, roots
noxious weeds - ANSWER >>>control is required by law; common
ragweed, giant ragweed, marijuana, musk/Canada thistle
exotic weeds - ANSWER >>>cannot be sold/used without permit
issued by govt; Japanese honeysuckle, Chinese buckthorn, giant

through bark and sapwood; interrupt sap flow
grubbing - ANSWER >>>uprooting by pulling/digging
herbicides - ANSWER >>>chemicals used to control,suppress, or kill
plants
factors to be considered when using chemical control - ANSWER
>>>environmental risks, weather, soil textures, proximity to water
growth regulators - ANSWER >>>chemically slow down plants; best
used steep slopes or areas when mowing is difficult
factors that can lessen penetration or absorption - ANSWER >>>leaf
surface/cuticule waxes
photosynthetic inhibitors - ANSWER >>>prevent photosynthesis in
plants; chlorosis/rapid wilting; nonselective
growth hormones - ANSWER >>>causes growth abnormalities; used
on foliage; leaf rolling/twisting of stems
meristematic inhibitors - ANSWER >>>affect growing points of plants
phosphono amino acid derivatives - ANSWER >>>applied to foliage
because they have very little soil activity; chlorosis; stunting and
narrow upright leaves
ACCase Inhibitors - ANSWER >>>foliar applied herbicides that
selectively control grass; broadlead unaffected
ALS enzyme inhibitors - ANSWER >>>absorbed through the foliage
and roots and translocated to growing areas; growth stops
immediately
