Which cultural management strategy specifically targets reducing pest damage by using endophytic grasses?

• A. Endophytic grasses increase the thatch
• B. Endophytic grasses reduce pest damage
• C. Endophytic grasses require more water
• D. Endophytic grasses are not used in turf

Answer: (B)

Endophytic grasses harbor a fungal partner inside their tissues that produces alkaloids deterring or harming many turf pests. This natural chemical protection means less feeding and injury to the grass, so pest damage is reduced without applying pesticides. It’s a cultural management approach because it relies on the plant–fungus relationship itself to provide ongoing pest protection as the grass grows. In turf systems, this endophyte-based resistance helps curb damage from common chewing and root-infesting insects. The other statements don’t reflect this pest-reduction mechanism, since they describe traits like increased thatch, higher water needs, or not using endophytes at all.
