Which term describes diseases caused by non-biological factors such as weather or soil conditions?

• A. Noninfectious diseases
• B. Infectious diseases
• C. Noxious weeds
• D. Pests

Answer: (A)

Noninfectious diseases describe problems caused by non-biological factors rather than by living pathogens. Weather stress, soil conditions, nutrient imbalances, or chemical injury can produce disease-like symptoms in turf, but there isn’t an infectious agent involved and the issue doesn’t spread from plant to plant. This is different from infectious diseases, which are caused by pathogens such as fungi, bacteria, or viruses. Noxious weeds and pests are organisms that harm plants, not diseases caused by abiotic factors.
