WYOMING RIGHTS-OF-WAY PEST
CONTROL. EXAM QUESTIONS AND
ANSWERS 100% PASS.
IVM - ANS Integrated vegetation management, uses several control methods to economically
and effectively control undesirable vegetation.
Native weeds - ANS Plants that have historic origins in the area and were not introduced by
human activity.
Introduced plants - ANS Came from other parts of the country or world through human
activities, animal movements, and water flow.
How do weeds spread - ANS Weeds spread when seed or growing plant parts (roots,
rhizomes, stems) are moved or carried into new territory.
People - ANS Unintentionally move and introduce weeds over long distances.
Wind - ANS Carries many seeds to new areas.
Water - ANS Rain, irrigation, and surface runoff also transport many seeds.
Carry seeds on their bodies, dropping them into new areas - ANS Mammals, birds, and
humans.

, How do weeds establish - ANS Any practice that disturbs the soil or ground cover and leaves
an opening for weeds to germinate will help weeds invade that area.
Grasses - ANS Have only one leaf, which is narrow and upright. Leaf veins run paralled to leaf
margins.
Herbaceous broadleave plants - ANS Have two seed leaves and die back to the ground each
winter. Their leaves are usually broad with netlike veins.
Woody plants - ANS Form wood and do not die back during the winter. they include brush,
shrubs, and trees.
annual plants - ANS complete their life cycle in less than 12 months. Normally annuals are
the easiest weed type to control, though they are the most common in disturbed areas.
Summer annual - ANS Plants germinate (sprout from seed) in the spring or summer. they
grow, flower, set seed, and die before winter. The seeds lie dormant in the soil until the next
spring or several springs later, when the cycle repeats itself
Winter annual - ANS plants germinate in the late summer to early winter. they overwinter in
a vegetative stage. In the spring or early summer, they flower, set seed, mature, and die, but live
for less than one full year. the seeds lie dormant in the soil during the summer months.
Biennial plants - ANS Their life cycle within two years. In the first year, the plant forms basal
leaves (rosette) and a top root. The second year the plant flowers, matures, and dies. there are
no biennial grasses or sedges.
Perennials - ANS Live more than two years, and some may live almost indefinitely,
resprouting from vegetative plant parts.
