What does host resistance involve in pest management?

Host resistance in pest management refers to the strategic approach of breeding or selecting plants that possess inherent qualities allowing them to resist or tolerate pest attacks. This method enhances the plant's ability to survive pest pressure without relying heavily on chemical interventions. By developing varieties that are resistant to specific pests, the impact of pests on crop yield can be minimized, leading to more sustainable agricultural practices.

This approach not only helps in reducing the reliance on pesticides, avoiding potential negative environmental impacts and health risks associated with chemical usage but also contributes to long-term pest management strategies by promoting natural ecosystem balance. The focus on breeding pest-resistant varieties provides a proactive method to manage pest populations rather than a reactive one, which typically involves chemical applications after pest problems have already developed.
