What is an endophyte in relation to turfgrass?

• A. A grass variety suitable for all climates.
• B. A fungus within the plant that deters certain insects.
• C. A method of fertilization.
• D. A type of mechanical pest control.

Answer: (B)

An endophyte is a symbiotic fungus that lives within the tissues of certain grass species, including many cool-season turfgrasses. This relationship is beneficial for both the plant and the fungus. The endophyte can produce alkaloids and other compounds that help deter herbivorous insects, thereby providing the turfgrass with a form of natural pest resistance. This association can lead to healthier grass that requires fewer chemical pesticides, thus promoting sustainable turf management practices. The other options do not accurately define an endophyte. For instance, a grass variety suitable for all climates does not specifically relate to the concept of endophytes. Likewise, a method of fertilization or mechanical pest control does not incorporate the biological relationship between fungi and turfgrass. Therefore, the correct characterization of an endophyte’s role in turfgrass aligns with the pest-deterring function it provides through its relationship with the plant.
