Integrated Pest Management (IPM)

Definition of IPM 

Pest management is a system of plant protection which utilize all suitable techniques to  reduce and maintain pest population at levels those causing injury of economic significance to  agriculture and forestry.

A system which brings together all feasible method of pest control, harmonizing them into a  single unified and co­ordinate system designed to maintain pest at levels below those at which  they cause economic loss.

Pest management is the intelligent selection and use of pest control action that will ensure  favourable  economic,  ecological  and  sociological  consequence.  The  practices  of  pest  management has been described by Geir (1966) as;

a. Determining how life system of a pest needs to be modified to reduce its number to  tolerable levels that is below the economic threshold.

b. Applying biological knowledge and recent technology to achieve the desired modification  that is applied ecology.

c. Revising procedures for pest control selected to current technology and compatible with  economic, environmental and social acceptance.

Benefits of IPM 

1. IPM increases crop yield and farmers income.

2. The use of insecticides may be reduced up to 80% of total use of crop yield may be  increased upto 10% through IPM.

3. IPM conserves ecosystem and ensures reliability and stability of farm output.

4. IPM reduces the risk of farmers and the public.

5. It helps farmer to become self reliant.

6. It helps to reduce the national expenditure for pesticides.

7. IPM reduces health care cost.

8. It increases the savings of farmer.

9. IPM directly helps to increasing farmers income.


Disadvantage of IPM 

However, IPM does have some disadvantages. These include:

1.  More involved planning.

2.  More family decision­making.

3.  More demanding lawn and garden care.

4.  More resources needed as substitutions for pesticides.

5.  Requires a greater amount of outside knowledge.

6.  Time and energy consuming.

7.  More involvement in the technicalities of the method


Some problem associated with the use of pesticides 

1. Pesticides causes the health hazards.

2. Pesticides are extremely unfriendly to the environment.

3. Pesticides destroy the beneficial organism and increased the pest population.

4. Reported application of pesticides makes the pest resistance to insecticides.

5. Pesticides affect the soil fertility.

6. It may create new pest problem.

7. It increases the input cost.
