Q1. What is Integrated Crop Management (ICM)?
ANSWER ICM is a whole-farm approach that uses all appropriate techniques
and methods to grow crops in economically viable, socially acceptable, and
environmentally responsible ways, balancing productivity with environmental
stewardship.
Q2. What are the core principles of ICM?
ANSWER The core principles include site assessment, variety selection, soil
management, nutrient management, crop protection, water management, energy
efficiency, biodiversity conservation, and continuous monitoring and evaluation.
Q3. How does ICM differ from conventional farming?
ANSWER ICM integrates multiple disciplines and decision-support tools
rather than relying solely on chemical inputs. It considers economic thresholds,
biological controls, and environmental impacts before applying pesticides or
fertilizers.
Q4. How does ICM differ from organic farming?
Page 1 of 51
, ANSWER ICM allows judicious use of synthetic inputs when necessary,
whereas organic farming prohibits them entirely. ICM prioritizes efficiency and
integration while organic relies exclusively on natural inputs.
Q5. What is the role of monitoring in ICM?
ANSWER Regular monitoring of crop growth, pest populations, soil
conditions, and weather allows farmers to make timely, evidence-based
decisions and intervene only when necessary, reducing unnecessary inputs.
Q6. What is an economic threshold in ICM?
ANSWER An economic threshold (ET) is the pest density at which the cost of
control equals the expected economic damage if no action is taken, guiding
farmers on when intervention is justified.
Q7. What is an economic injury level (EIL)?
ANSWER The EIL is the lowest pest population density that causes economic
damage equal to the cost of control measures, setting the basis for intervention
decisions.
Q8. Why is record keeping important in ICM?
ANSWER Records document inputs, yields, pest occurrences, and
interventions over time, enabling analysis of trends, compliance with
regulations, and informed future management decisions.
Q9. What is the decision hierarchy in ICM?
ANSWER Prevention first, then avoidance, then monitoring, then suppression.
Chemical control is the last resort, used only after other methods prove
insufficient.

,Q10. What does the term 'whole-farm approach' mean in ICM?
ANSWER It means ICM considers all farm operations together — soil health,
crop sequences, water use, wildlife habitats, and business economics — rather
than managing each in isolation.
Q11. What is a farm management plan in ICM?
ANSWER A structured document outlining all farm activities, inputs,
cropping sequences, conservation measures, and monitoring schedules to
achieve ICM goals over a season or several years.
Q12. What role does technology play in modern ICM?
ANSWER Technologies such as GPS, remote sensing, precision agriculture
tools, GIS mapping, and decision support software help farmers apply inputs
precisely where and when needed, reducing waste.
Q13. What is precision agriculture and how does it relate to ICM?
ANSWER Precision agriculture uses data and technology to manage spatial
variability in fields. It supports ICM by enabling variable rate application of
inputs, reducing overuse and environmental impact.
Q14. What is the purpose of crop scouting in ICM?
ANSWER Crop scouting involves systematic field inspections to assess pest,
disease, and crop health status, providing the data needed to make timely
management decisions.
Q15. What is integrated weed management?
Page 3 of 51
, ANSWER A strategy within ICM that combines cultural, mechanical,
biological, and chemical methods to reduce weed pressure while minimizing
herbicide resistance and environmental impact.
Q16. What is the significance of biodiversity in ICM?
ANSWER Biodiversity supports natural pest regulation, pollination, and soil
health. ICM promotes habitat features such as hedgerows and wildflower
margins to support beneficial organisms.
Q17. How does ICM support environmental sustainability?
ANSWER By reducing unnecessary chemical inputs, protecting water quality,
promoting soil health, supporting biodiversity, and lowering greenhouse gas
emissions from farm operations.
Q18. What is the role of soil analysis in ICM?
ANSWER Soil analysis identifies nutrient levels, pH, organic matter, and
structure, enabling farmers to apply only what is needed and avoid waste or
environmental damage.
Q19. What is a field margin and why is it important in ICM?
ANSWER A field margin is a strip of land at the edge of a crop field managed
for conservation purposes. It provides habitat for beneficial insects, reduces
runoff, and supports biodiversity.
Q20. What is an action threshold in ICM?
ANSWER The pest density at which management actions must be taken to
prevent the population from reaching the economic injury level, providing a
buffer for timely intervention.
