What is a common rationale for using endophyte-enhanced fescue or ryegrass in turf pest management?

• A. They reduce vulnerability to certain pests.
• B. They require more water.
• C. They are more expensive with no benefit.
• D. They improve color only.

Answer: (B)

Endophyte-enhanced fescue or ryegrass are used in turf pest management mainly because the symbiotic fungus inside the grass produces alkaloids that deter or harm many common turf pests. These compounds make the grass less palatable or even toxic to chewing insects and some soil-dwelling pests, reducing damage and often lowering the need for chemical controls. That pest-deterrent effect is the primary reason managers choose endophyte-infected varieties. Water needs, cost with no benefit, or simply improved color aren’t the driving factors in this context.
