What is a potential drawback of using endophyte-infected grasses?

• A. No drawbacks
• B. Possible negative effects on non-target organisms and changes in pest dynamics
• C. They completely replace pest management
• D. They always improve turf performance

Answer: (B)

Endophyte-infected grasses produce natural compounds that can deter certain pests, helping protect the grass. But these compounds aren’t perfectly selective. They can affect non-target organisms, including beneficial insects or wildlife, and they can shift how pest populations behave over time, sometimes leading to changes in which pests are a problem or how severe they are. So the key drawback is the potential negative effects beyond the intended pests and the possibility of altered pest dynamics. The other statements assume no downsides, complete pest replacement, or universal turf gains, which isn’t accurate.
