Using resistant or endophytic turfgrass cultivars is a cultural strategy to reduce disease and insect damage.

• A. True
• B. False
• C. Not recommended
• D. Only reduces insects

Answer: (A)

Using resistant or endophytic turfgrass cultivars is a cultural approach to reducing disease and insect damage. Resistant cultivars carry genetic traits that limit how diseases can infect and spread, which lowers disease pressure on the turf. Endophytic grasses host fungal partners that produce alkaloids or other compounds deterring or harming insect pests, leading to less feeding and damage. Because these traits work without chemical pesticides, they reduce the need for chemical controls and fit into an integrated pest management approach. It's still possible for some diseases or pests to overcome resistance or for endophyte effects to vary by species and environment, so while beneficial, they are not a guarantee against all damage. Overall, this strategy is a valid and helpful part of managing turf health.
