What are some examples of cultural control methods? -
ANSWER-Choosing plants that are well-suited for the site, using
weed-free plant material, using alternatives to vegetative ground
covers if needed, address weeded areas ASAP, and clean
equipment after use
What is the cultural tactic of controlled/prescribed burning used
for? – ANSWER-Temporarily removes unwanted vegetation
What are the disadvantages of using biological controls to
control weeds in rights-of-way areas? - ANSWER-Doesn't
eliminate the weed population, only reduces the severity of
infestation; species specific
What are the benefits/drawbacks of mowing? - ANSWER-Makes
grass thicker and more competitive with weeds; cutting too
short can increase erosion and broadleaf invasion; must be
properly timed
,What are the benefits/drawbacks of cutting? - ANSWER-
Expensive; best for small areas; increased selectivity of what is
removed; stalks must be removed to prevent regrowth
What are the benefits/drawbacks of girdling? - ANSWER-Labor-
intensive; only effective for scattered big trees; takes years for
effects to be seen; effectiveness can be increased with herbicide
What are the benefits/drawbacks of grubbing? - ANSWER-
Difficult; time consuming; costly; removing as much of the root
system as possible yields the best results
Why are chemicals commonly used in right-of-way areas? -
ANSWER-Less labor-intensive, less time consuming, and more
economical than other types of control
What are the six factors that should be considered before using
chemical controls? - ANSWER-Financial and environmental
risks; proximity of sensitive plants; weather and site conditions;
impacts on non-target species, local pesticide ordinances,
application methods, equipment, etc; method of chemical use
(complimenting other forms of vegetation control)
, Where is the use of growth regulators most useful? - ANSWER-
Areas where mowing is difficult (hills/slopes, cemeteries, etc)
and herbicide-sensitive areas
What seven factors should be considered when selecting a
herbicide? - ANSWER-Type of weeds present, length of control,
climate, soil type, cost, nontarget impact, and plant
physiological processes
What factors can lessen or prevent the penetration or absorption
of herbicides? - ANSWER-Leaf surface (cuticle waxes and hairs),
degradative soil processes, and metabolism
What are the five ways in which herbicides are classified? -
ANSWER-
Selective/nonselective, systemic/contact,
persistent/nonpersistent, how they are absorbed by plants, and
by mode of action
What may selectivity be dependent on? - ANSWER-The range of
plants they control, amount of injury to other plants, rate, timing,
method of application, and plant characteristics
