Which IPM method involves changing cropping practices to suppress pests?

• A. Cultural control
• B. Mechanical control
• C. Regulatory control
• D. Biological control

Answer: (A)

Cultural control in IPM uses changes to how the crop is grown to reduce pest pressure. By altering practices such as crop rotation, planting dates, residue management, spacing, sanitation, and the use of resistant varieties, the crop environment becomes less hospitable to pests or disrupts their life cycles. For example, rotating to non-host crops breaks pest population buildup, adjusting planting times avoids peak pest activity, sanitation removes residues and volunteer plants that harbor pests, and using resistant varieties reduces pest success. This approach focuses on the cropping system itself rather than applying pesticides, barriers, or releasing predators, which are the roles of mechanical, regulatory, and biological controls respectively.
