–competes with humans, domestic animals,
or desirable plants for food or water.

13. •To control a pest only
when it is causing or is
expected to cause
more harm than is
reasonable to accept.

Pest Control is…….

14. •To use a control
strategy that will
reduce the pest
numbers to an
acceptable level.

Pest Control is…….
EMW3

15. •To cause as little harm
as possible to
everything except the
pest.

16. Pest Control Goals
•Prevention
•Suppression
•Eradication
16EMW3

17. Threshold Levels……
•Are the levels of pest
populations at which pest
control action needs to be
taken to prevent the pest
from causing unacceptable
injury or harm.
17EMW3

18. Avoiding Harmful Effects
•Choose the pest control
method that will best
control the pest with the
least harmful effect to the
environment.
18EMW3

19. Integrated Pest
Management (IPM) is…
•the combining of
appropriate pest control
tactics into a single plan
to reduce pests and their
damage to an acceptable
level.
19EMW3

20. •To solve pest problems using
IPM:
–Identify the pest
–Is control needed?
–What controls are available?
–Evaluate the risks and benefits

21. •To solve pest problems (con't):
–choose a control strategy that will be
most effective and cause the least harm
to people and the environment
–use each tactic in the strategy correctly
–observe Local, State, and Federal laws.

22. •Natural Controls
–climate
–natural enemies
–natural barriers
–food and water supply
–shelter

Integrated Pest

23. •Applied controls
–host resistance
•resistant varieties
–biological control
•natural enemies
–cultural control
•plowing, crop rotation, fertilizing, etc.

Management (IPM) is

24. •Applied controls (con't)
–mechanical control
•traps, screens, fences
–sanitation
•remove crop residues, cleanliness
–chemical control
•use of pesticides

Management (IPM) is

25. IPM Monitoring (questions to ask)
•What kinds of pests are present?
•Are the numbers great enough to
warrant control?
•Have the control efforts successfully
reduced the number of pests?
25EMW3

26. Pest Control Failures
•pest is resistant to pesticide
Pesticide resistance describes the decreased susceptibility of a pest 
population to a pesticide that was previously effective at controlling the 
pest.

31. •A PEST is anything that competes, injures, spreads
disease, or annoys humans, domestic animals, or
desirable plants.
•Pest Control is to control a pest only when it is
causing or is expected to cause more harm than
is reasonable to acceptable.
•Integrated Pest Management (IPM) is the
combining of appropriate pest control tactics into
a single plan to reduce pests and their damage to
an acceptable level.
