What plant factors can influence pest susceptibility?

Plant health, variety, and growth stage are significant factors that influence pest susceptibility. Healthy plants typically have stronger defenses against pests, while unhealthy plants may be more vulnerable due to weakened immune responses. The variety of the plant can also play a crucial role; some varieties are bred specifically to withstand certain pests or diseases, thereby showcasing varying levels of resistance or susceptibility. Additionally, the growth stage of a plant is critical; young, tender seedlings might be more susceptible to pests compared to mature plants that have developed tougher tissues and stronger chemical defenses. Understanding these factors can help pest management professionals develop effective strategies to protect plants and mitigate pest infestations.
