ANSWERS PRACTICE SOLUTION TESTED
MATERIAL
●● Economic threshold for pests control
Answer: the level that a pest population much reach before it becomes
cost-effective to treat them. For landscapes, the most important factor in
pest management is generally appearance.
●● Natural factors that influence pests
Answer: Include climate, natural barriers and enemies, population
development ad dynamics and the availability of shelter, food, and
water.
●● Chemical Control
Answer: There are two approaches to to help control pests in landscapes:
Preventive involves applying a pesticide before the problem appears.
Reactive or curative treatments occur after you notice the pest or its
damage.
●● Protecting water sources
Answer: Do not use more than the label directs
,Mix pesticides 100 feet from surface water or a direct link
Prevent pesticides from back-siphoning into your water source
Factor in irrigation, soil type, and weather forecasts when deciding when
and how much pesticide to apply.
Use buffer strips around water sources and hard surfaces to reduce
pesticide movement.
●● Pesticide Movement
Answer: Drift, runoff and leaching
●● Drift
Answer: The unintended movement of pesticide through the air during
or after application.
●● Particle drift
Answer: The movement of droplets through the air during or soon after
application
●● Vapor drift
Answer: occurs when pesticides land on the target site but then turn into
vapor and move off-target
●● Runoff
, Answer: the movement of pesticides across the treated surface, such a
lawn. Can contaminate water through runoff if it lands on concrete or
sidewalk.
●● Leaching
Answer: Occurs when chemicals move downward through the soil in
water. Leaching is likely in sandy soils than dry.
●● Pesticide Residues
Answer: The Trace amount of pesticides that remains in the environment
after it is applied is known as residue. All pesticides break down, or
degrade after application.
●● MOA
Answer: Mode of action. Most instances of resistance have arisen
because applicators have relied too much on pesticides with the same
mode of action.
●● Pesticide Adjuvants
Answer: Adjuvants are products designed to make pesticides more
effective.
●● Surfactants
