How does plant resistance work in biological control?

Plant resistance in biological control refers to the inherent ability of certain plant varieties to withstand or deter pest attacks. This can be achieved through various mechanisms, including physical barriers (like thicker leaves or tougher skins) and biochemical defenses (such as the production of toxic compounds or repellents that discourage pests from feeding on them). By breeding and selecting plant varieties with these resilient traits, agricultural practices can reduce the reliance on chemical pesticides while promoting a more sustainable approach to pest management.

This method not only helps in minimizing pest populations but also supports overall ecosystem health by maintaining beneficial organisms that might otherwise be harmed by broad-spectrum pesticides. It enhances the plant's ability to survive and thrive even in the presence of pests, contributing significantly to integrated pest management strategies.
