Disease the economic threshold
management attempts to maximize
profits by reducing disease severity to:
Pest competes with humans, domestic animals, or crops for food,
feed or water
Injures humans, animals, crops, structures, or possessions
Spreads disease to humans, domestic animals, or crops
annoys humans or domestic animals
Pest five categories insects (and related animals)
plant disease agents
weeds
mollusks
vertebrates
,To be able to identify and control pests, the common features of pest organisms
you need to know about some aspects of:
characteristics of the damage they cause
pest development and biology
To solve pest problems, the applicator must identify the pest
know what control methods are available
evaluate the benefits and risks of each method or
combination of methods,
choose the methods that are most effective and will cause
the least harm to people and the environment
use each method correctly
observe local, state and federal regulations that apply to the
situation
The most important principle of pest Use a pesticide only when necessary and the lowest labeled
control is rate which will prevent the pest from causing more damage
that is reasonable to accept
,Successful pest control is based on the keep pest damage to a minimum by choosing an appropriate
ability to: combination
of control methods
recognize when direct action, such as a pesticide application,
is necessary
endanger the environment as little as possible
Some forces which affect the pest Climate
population include: Natural enemies
Topography
Food
Water Supply
Host resistance works in two main ways: chemicals in the host prevent the pest from completing its life
cycle
the host is more vigorous or tolerant than other varieties and
thus less likely to be seriously damaged by pest attacks
, Biological control can be: A low-cost control method particularly suited to low-value
crops (pastureland, clover, and hay crops)
Or in areas where some injury can be tolerated (golf course
fairways, forest areas)
Cultural practices are: Agricultural practices used to alter the environments, the
condition of the host, or the behavior of the pest to prevent
or suppress infestation
Mechanical control Devices and machines used to control pests or alter their
environment
What is used to prevent the spread of pests Traps, screens, barriers, radiation and electricity
or reduce infestation:
Sanitation practices: Help to suppress some pests by removing sources of food
and shelter
Chemical control: Pesticides are chemicals used to destroy pests, control their
activity, or prevent them from causing damage
Chemicals which regulate plant growth or Pesticide
remove foliage may also be classified as:
