Exаmine the fоur scenаriоs Scenаriо 1 Scenario 2 Scenario 3 Scenario 4 Crop rotation is implemented to disrupt the life cycles of soil-dwelling pests, and trap crops are planted at field edges to attract pests away from the main harvest. Biological controls and cultural practices work together to reduce overall pest pressure sustainably. A farmer applies a predictive pest management model, scheduling targeted insecticide applications based on historical data, weather forecasts, and remote sensing of plant stress. This high-tech approach appears strategic and precise but does not integrate natural predators or cultural practices. Farmers deploy genetically modified pest-resistant crops combined with enhanced irrigation and nutrient management to optimize plant growth and minimize stress-related vulnerability to pests. A farmer monitors crop fields regularly for early signs of pest activity and introduces natural predators, such as ladybugs, to control aphid populations. Chemical treatments are only applied if pest levels exceed safe thresholds. This approach minimizes pesticide use while maintaining crop health.
