For pest-related crop losses, what mitigation strategy is commonly used?

• A. Increasing irrigation frequency
• B. Integrated Pest Management and resistant varieties
• C. Using only organic matter as fertilizer
• D. Removing crop residues completely

Answer: (B)

The most effective way to reduce pest-related losses is to use an integrated approach that combines several practical tactics rather than relying on a single method. Integrated Pest Management (IPM) centers on monitoring pest presence and levels, setting action thresholds, and using a mix of controls—cultural practices, biological controls, habitat management, and the use of pest-resistant crop varieties. By combining these strategies, you weaken pest pressure while conserving natural enemies and delaying the development of resistance to any one control method.

Resistant varieties are especially helpful because they lessen the pest’s ability to establish, feed, or reproduce, directly reducing damage without needing constant chemical interventions. When grown with IPM, these varieties complement other actions, creating a robust defense against pests.

The other options don’t provide the same breadth or sustainability. Merely changing irrigation can influence pest dynamics but often doesn’t address the pest problem comprehensively and can raise disease risk if overused. Relying on organic matter as fertilizer improves soil health but doesn’t specifically target pests. Removing crop residues completely can reduce some overwintering sites for pests, yet it harms soil health and isn’t a reliable, universal pest solution.
