1.Era of traditional approaches(ancient-1938):cultural
&mechanical practices like crop rotation, field
sanitation, deep ploughing, flooding etc developed by
farmers through experience.
2.Era of pesticides(1939-1975):Synthetic inorganic and
organic pesticides, highly toxic to living organisms.
Began with discovery of DDT,BHC,HCH etc.
3.Era of IPM(1976 onwards):Idea of integrated control-
Hoskins et al. First defined by Stern et al. Idea of
protective population management – Gier and Clark

Need for Pest Management (or) Why Pest
Management
► 1. Development of resistance in insects against insecticides
e.g. OP and synthetic pyrethroid resistance in Helicoverpa armigera.
► 2. Out break of secondary pests e.g. Whiteflies emerged as major pest when spraying insecticide against H. armigera.
► 3. Resurgence of target pests e.g. BPH of rice increased when some OP chemicals are applied.
► 4. When number of application increases, profit decreases.
► 5. Environmental contamination and reduction in its quality.
► 6. Killing of non-target animals and natural enemies.
► 7. Human and animal health hazards.

Stages in crop protection leading to
IPM
► 1. Subsistence phase : Only natural control, no insecticide use
► 2. Exploitation phase : Applying more pesticides, growing HY varieties and get more yield and returns
► 3. Crisis phase : Due over use pesticides, problem of resurgence, resistance, secondary pest out break, increase in production cost
► 4. Disaster phase : Due to increased pesticide use - No profit, high residue in soil - Collapse of control system
► 5. Integrated Management Phase: IPM integrates ecofriendly methods to optimize
► control rather than maximise it.

Objectives of pest management
► 1. To reduce pest status below economic injury level. Complete
elimination of pest
► is not the objective.
► 2. To manage insects by not only killing them but by preventing feeding,
► multiplication and dispersal.
► 3. To use ecofriendly methods, which will maintain quality of environment (air,
► water, wild life and plant life)
► 4. To make maximum use of natural mortality factors, apply control measures only
► when needed.
► 5. To use component in sustainable crop production

Requirements for successful pest
management programme
► 1. Correct identification of insect pests
► 2. Life history and behaviour of the pest
► 3. Natural enemies and weather factors affecting pest population
► 4. Pest surveillance will provide above data
► 5. Pest forecasting and predicting pest outbreak
► 6. Finding out ETL for each pest in a crop
► 7. Need and timing of control measure - Decision
► 8. Selection of suitable methods of control
► 9. Analysis of cost/benefit and benefit/risk of each control measure
► 10. Farmer’s awareness and participation
► 11. Government support

MODELLING IN IPM
![Page 29: INTEGRATED PEST MANAGEMENT...Integrated Pest management refers to an ecological approach in pest management I n which all the available necessary techniques like physical ,chemical,cultural,mechanical](https://reader036.vdocuments.us/reader036/viewer/2022081402/5f1c96465b1c7625a7475b4c/html5/thumbnails/29.jpg)
► Institutional constraints: Lack of coordination among
disciplines,amond displines,reserch extension and
implementation among institutes hampers the
promotion of IPM
► Informational constraints: Lack of information about
IPM to farmers from Extension workers
► Sociological constraints: Convincing farmers about the
benefits of IPM
►Political constraints: Pesticide subsidy by the Govt for
political reasons
CONSTRAINTS OF IPM

IPM AND SUSTAINABLE AGRICULTURE
![Page 31: INTEGRATED PEST MANAGEMENT...Integrated Pest management refers to an ecological approach in pest management I n which all the available necessary techniques like physical ,chemical,cultural,mechanical](https://reader036.vdocuments.us/reader036/viewer/2022081402/5f1c96465b1c7625a7475b4c/html5/thumbnails/31.jpg)
Employment of principles of IPM is essential in
optimizing sustainability of agricultural systems.
1.Ecological stability:Ipm do not danger environment
2.social stability: inputs used in IPM are from local
sources, Pesticides from pesticide corporate industry.
3.Economical:IPM is cheap ,Feasible &Economical
When compared with pesticide
