What does "susceptible" mean in herbicide terminology?

In herbicide terminology, "susceptible" specifically refers to plants that are easily killed or affected by herbicide application. When a plant is classified as susceptible, it means that the herbicide in question interacts with the plant's physiological processes in a way that disrupts its growth or leads to its death. This term is crucial for understanding herbicide effectiveness and selecting the appropriate herbicide for managing specific weed populations.

Understanding susceptibility is essential for effective weed management strategies, as it allows applicators to predict which plants will be controlled by a particular herbicide and to ensure the most effective application rates and methods. The concept is key for both agricultural practices and invasive species management.
