Chemical controls. Controls

The plants provide the food (99%of the world food supply) either directly or indirectly.
Man, and other living organisms are dependent on plants for food.
The unwanted animals, plants or other forms of living organisms, that cause injury disease or destruction to man himself to desirable animals & plants as well as pests.
The control of various pests is necessary, and several steps must be taken prior to the selection of mode of control.
These controls are generally achieved either by natural controls or the controls practices developed by and applied by man.
The pests control methods are classified into two main groups.
1)Natural control and 2)Applied controls
1)Natural control:
It is a collective action of environmental factors, physical or biotic that maintain no of pest's population within certain upper & lower limits, over a period.
The important factors of natural control are climatological factors. (Heavy raining, hot sunshine, floods, availability lighting speedy wind, etc) natural enemies' availability of food and evolutionary pressure.
2)Applied controls:
These include a whole range of practices, developed or modified by man, that become necessary when natural control factors failed to control the pests.
The different methods under applied control are cultural mechanical, physical, biological, genetical, regulatory and chemical controls.
Identify the pest or pests and determine whether control is warranted for each.
Determine your pest control goal(s).
Know what control tactics are available.
Evaluate the benefits and risks of each tactic or combination of tactics.
Choose a strategy that will be most effective and will cause the least harm to people and the environment.
Use each tactic in the strategy correctly.
Observe local, State, and Federal regulations that apply to the situation.
Toxicity of pesticides
It is the property of substance that causes adverse effect in an organism.
Hazard(risk)-
It is a probability of adverse effect occurring.
Acute toxicity:
is that property of substance which adverse effect in organism through exposure of the substance in a single short term dose. It is expressed in mg\kg, mg\kg diet.

selection criteria for pest control Pest Resistance
Pesticides fail to control some pests because the pests are resistant to the pesticides. Consider this when planning pest control programs that rely on the use of pesticides. Rarely does any pesticide kill all the target pests. Each time a pesticide is used, it selectively kills the most susceptible pests. Some pests avoid the pesticide. Others withstand its effects. Pests that are not destroyed may pass along to their offspring the trait that allowed them to survive.
When one pesticide is used repeatedly in the same place, against the same pest, the surviving pest population may be more resistant to the pesticide than the original population was. The opportunity for resistance is greater when a pesticide is used over a wide geographic area or when a pesticide is applied repeatedly to a rather small area where pest populations are isolated. A pesticide that leaves a residue that gradually loses its effectiveness over time will help select out resistance. Rotating pesticides may help reduce the development of pest resistance. Integrated pest management is the combining of appropriate pest control tactics into a single plan (strategy) to reduce pests and their damage to an acceptable level.
Using many different tactics to control a pest problem tends to cause the least disruption to the living organisms and nonliving surroundings at the treatment site. Relying only on pesticides for pest control can cause pests to develop resistance to pesticides, can cause outbreaks of other pests, and can harm surfaces or non-target organisms.
With some types of pests, use of pesticides as the only tactic will achieve very poor control. Chemical Controls The use of pesticides has become necessary and accepted practices in agricultural, public health,
forestry, and animal husbandry. The pests controlled by chemicals called pesticides is a basic
tool and will be continued for efficient pests' management. The pesticides provide rapid,
effective, economical means of control of various pests. However, the problems associated with
their uses are increasing, and future development of new pesticides is alarming
Genetic control In this method two aspects are considered.
