Which statement best describes how bacterial diseases spread?

• A. Through wounds, insects, and rain splash
• B. Only through seeds
• C. Only through wind
• D. Only by irrigation water

Answer: (A)

Bacteria that cause plant diseases can move in several ways, not just one. They can enter through wounds in plant tissue, be carried by insects that feed on or move between plants, and be splashed from infected material to healthy tissue by rain. Because these routes cover the main pathways plants encounter in ornamental and turf environments, a description that includes wounds, insect vectors, and rain splash best describes how bacterial diseases spread. Other options are too narrow: seeds can carry some bacteria but that isn’t the only or always the primary route; wind can disperse some pathogens, but bacteria are not limited to wind spread; irrigation water can spread bacteria, yet it’s not the sole method.
