Integrated Pest Management (IPM) strategies include which of the following?

• A. Cultural controls
• B. Biological controls
• C. Mechanical/physical controls
• D. All of the above

Answer: (D)

Integrated Pest Management relies on combining several strategies to reduce pest pressures in a sustainable way. Cultural controls change farming practices to make the environment less favorable for pests, such as crop rotation, sanitation, calendar timing of planting, resistant varieties, and proper irrigation. Biological controls use natural enemies—predators, parasitoids, and pathogens—to suppress pests without synthetic chemicals. Mechanical or physical controls create barriers or remove pests, including nets or row covers, traps, hand-picking, tillage, and solarization. When these methods are used together as part of a monitoring-based approach, pest thresholds, and careful decision-making, the need for chemical controls is minimized. So, IPM includes all of these approaches, making the option that encompasses them all the best fit.
