Which method involves aquatic movement of fungal spores?

• A. Air
• B. Insects
• C. Water splash
• D. Swimming spores (zoospores)

Answer: (D)

Motile spores that move through water drive aquatic dispersal. These swimming spores, called zoospores, have flagella and swim in water, allowing them to travel through irrigation, puddles, or wet turf to reach plant tissues and establish infection. This distinguishes them from spores dispersed by wind, by insects, or simply moved by water splashes, which rely on different mechanisms for transfer. In turf and ornamental diseases, such as those caused by Pythium or Phytophthora, zoospores enable the pathogen to spread in wet conditions where the spores can swim toward susceptible roots or crowns before germinating.
