What is a plant disorder?

Explanation:
Plant disorder refers to a problem in a plant that is not caused by a living pathogen. It results from abiotic or nonpathogenic factors, meaning nonbiological conditions or noninfectious issues like drought, frost or heat damage, nutrient imbalances, chemical injury from fertilizers or herbicides, and other environmental stresses. This distinguishes disorders from diseases caused by fungi, bacteria, or viruses, and from damage caused by pests. A hereditary trait is a genetic characteristic, not an injury or dysfunction from external factors, so it isn’t a disorder in this sense.
