What does plant susceptibility refer to?

Plant susceptibility refers to the level of vulnerability a plant has to external stress factors, including herbicides. When a plant is susceptible to a herbicide, it is more likely to be affected negatively—whether that means it gets killed or injured by the chemical treatment. This susceptibility can vary widely between different plant species and even between different varieties of the same species, based on their physiological and genetic characteristics.

Recognizing the susceptibility of plants helps in making informed decisions about herbicide application to avoid unwanted damage to desirable plants while effectively managing weeds. The correct choice highlights the direct relationship between herbicide application and the resulting impact on plant health. Understanding this concept is crucial for effective pest management in turf and ornamental practices, where the goal is to minimize harm to desired flora while controlling pest populations.
