Which of the following pest control techniques includes breeding plants for certain traits to make the plant resistant?

Host-plant resistance is a pest control technique that focuses on breeding plants to exhibit specific traits that confer resistance to various pests. This method entails selecting and cultivating plants that have natural attributes making them less susceptible to damage from insects, diseases, or weeds. By enhancing these traits through selective breeding, the resulting plants can effectively deter pests, minimize the need for chemical pesticides, and promote sustainable agricultural practices.

In contrast, mechanical techniques involve physical actions taken to control pests, such as trapping or removing them. Regulatory methods consist of legal or administrative actions, usually aimed at preventing the introduction or spread of pests through control of products and practices. Biological pest control utilizes living organisms, such as predators or parasites, to manage pest populations. While these approaches are valuable in integrated pest management, they do not directly involve the genetic enhancement of plants for resistance traits, which is the defining characteristic of host-plant resistance.
