What is the term for the death of weeds?

Necrosis is the term used to describe the death of plant tissues, including weeds. In the context of weeds, necrosis indicates that the cells within the plant are dying due to various factors, such as chemical action from herbicides, environmental stress, or disease. When a weed experiences necrosis, it typically loses its ability to function properly, which ultimately leads to its death.

Chlorosis refers to the yellowing of plant leaves due to insufficient chlorophyll and is often a sign of nutrient deficiency rather than death. Erosion involves the removal of topsoil or other materials, affecting the environment but not directly connected to the death of a weed. Decomposition is the process of breaking down dead organic matter, which occurs after a plant has died, rather than indicating the active death process itself. Thus, necrosis is the most accurate term to describe the death of weeds.
