List the four categories of control methods and briefly explain
each.
Mechanical - may be mechanical or manual removal, cutting,
etc.
Biological - work to enhance the effects of natural enemies of
pests
Chemical - use herbicides/pesticides
Cultural - create optimal growing conditions for the plants you
want to preserve or unfavorable conditions for the pest
How does shading work as a cultural control? Where is it often
used?
Block sunlight from unwanted plants to keep them from
growing; often used in aquatic ecosystems to control weeds by
shading them with black plastic, adding dye to the water, or

,Only certain plant species are considered undesirable, so
others are usually left on the right-of-way for other benefits
Why is it important to protect wetlands?
Because they are declining and they are valuable ecosystems
because they protect wildlife, minimize bank and shoreline
erosion, improve water quality, provide recreational activities,
and act as water storage during flooding
List four stages of weed development and briefly describe
each.
Seedling - small, vulnerable plantlets
Vegetative - rapid growth producing stems, roots, and foliage,
uptake of water and nutrients is rapid
Seed production - energy directed toward production of seed,
uptake of water and nutrient is slow and directed towards
flower, fruit, and seed structure
Maturity - little or no energy production or movement of water
and nutrients

year or less
Biennials - plants with two-year life cycle
Perennials - plants that live more than two years and may live
indefinitely
_____ is the use of all available tactics or strategies to manage
pests so that acceptable control can be achieved.
IPM (integrated pest management)
Why must weeds and woody plants be managed on rights-of-
way?
For safety, access to facilities, decrease maintenance costs,
reliability of service, and for other benefits like aesthetics,
wildlife, and environmental protection
True or False: The first component of an effective pest
management program is pest identification.
