  1. 1. “Integrated Pest Management (IPM)” By Jitendra Kumar Singh M.Phil/Ph.D School of Environment and Sustainable Development Central University of Gujarat
  2. 2.  Integrated Pest management (IPM) is defined as a pest management system that utilizes suitable techniques and methods against the pests in as compatible manner with the environment as possible and thus, maintaining the pest population levels below those causing economic injury. IPM is a vital component of sustainable agriculture. It reduces the emphasis on pesticides by including cultural, biological, and mechanical controls. IPM related activities are being implemented through 26 Central Integrated Pest Management Centers (CIPMCs) located in 23 States and Union Territories.
  3. 3. Crop Losses due to pestsAverage 18% of the crop yield is lost due to pests.Annual monetary loss in India is: Rs.60,000 Crores.

  6. 6. Consumption of pesticides by different crops (%)
  7. 7. Objective of IPM1. Reduced Crop loss.2. Minimize environmental pollution.3. Reduced chemical contamination of food and the environment.4. Maintain ecological balance with minimum disturbance to ecosystem.5. Reduce management cost.6. Reducing Pesticide Use.7. Maximum crop production.
  8. 8. IPM Option for sustainable agricultureIPM Options may be considered Proactive or Reactive.Proactive option such as crop rotation, creation of habitat for beneficialorganisms and permanently lower the carrying capacity of the farm for thepest.Cultural controls are generally considered to be proactive strategies.The second set of option is more reactive.Reactive option generally include biological, mechanical & physicalcontrols and chemical controls.
  9. 9. IPM Continuum
  10. 10. IPM System IPM can be applied wherever pests are found: on and in farms, schools, homes, hospitals, restaurants, golf courses and home gardens. • IPM system is designed around six basic components1. Acceptable pest levels - IPM programmes first work to establish acceptable pest levels, called action thresholds, and apply controls if those thresholds are crossed.2. Preventive cultural practices3. Monitoring4. Physical and Mechanical controls5. Biological controls6. Responsible Pesticide Use (Chemical controls)
  11. 11. Control Methods Used in IPMCultural control: using crop rotation, cultivation, sanitation, habitat control modification, or removal of sources of pest infestation.Physical control: using barriers, traps, trap crops; planting, fertilization, control tillage, or harvest times.Biological control: conservation or introduction of predators, parasites, control and diseases that suppress or attack pests.Chemical control: select and use the least toxic, environmentally control suitable pesticides in the lowest effective amounts to control pests.Genetic control: using plant varieties that are resistant to pest injury. control
  12. 12. IPM = Sustainable Pest Management?
  13. 13. Biological control Increase of predatory populations Each pest has natural predators, parasites and competitors. Bring equilibrium predator-prey below the economic threshold of pest.

  15. 15. Technology for Pest management • Biological control • Cultural control • Legal control • Synthetic pesticides
  16. 16. Case studyIn Tamil Nadu (2012) Integrated pest management practices in sericulture
  17. 17. IPM Non-IPM
  18. 18. Benefits/Advantage of integrated pest management  IPM protects the environment and our health.  IPM is less damaging to essential soil health and nutrient cycling.  Better plant health giving improved quality and production.  Decreased use of chemical application may result in a financial savings.  Ecological sustainability by conserving natural enemy species, biodiversity, and genetic diversity.
  19. 19. Future IPM Research1. Biotechnological approaches for pest management • Marker-assisted selection • Exploitation of wild relatives for resistance to insect pests and diseases • Genetic engineering of crop plants for resistance2. Characterization and diagnosis of plant pathogens and insect pests, and environmental biosafety of transgenic crops.3. Host plant resistance and integrated pest management • Introgression of resistance genes into high yielding varieties and hybrid parents • Strategic research to improve the efficiency of genetic enhancement • Integrate IPM components and validate their effectiveness for insect pest
  20. 20. IPM technology can provide green and eco-friendlyalternatives for environment and agricultural managementwithout harming the nature by the help of pest controllingmethods.Many case studies concluded that Benefit Cost Ratio (BCRatio) was more for IPM farm, compared to Non-IPM farms.
