What term describes a non-pest plant stress such as improper nutrition or water levels?

The term "abiotic disorder" accurately describes a non-pest plant stress that results from environmental factors such as improper nutrition, water levels, temperature extremes, and other non-living elements affecting plant health. Unlike biotic disorders, which are caused by living organisms like pests, pathogens, or diseases, abiotic disorders are linked to the physical and chemical aspects of the environment.

Recognizing abiotic disorders is crucial for effective plant care, as identifying these stresses allows for the adjustment of treatment and management strategies to improve plant vigor and resilience. Understanding abiotic factors helps in diagnosing issues that do not arise from pest infestations but rather from the growing conditions surrounding the plants.
