Improving Turfgrass Through Research
Fine Fescue-Why?
• High stress tolerance - significant improvements
• Use for low maintenance turf alone or as major percentage in blend
• Improved cultivars allow use as high quality turf
• All endophyte enhanced
• Not just for shade mixtures
• Develop mixtures and actively promote improvements

Improving Turfgrass Through Research
Fine Fescue Performance
• Low maintenance fairway trials - WI, MN, IL– Colonial bentgrass + fine fescues– Fine fescues mixtures– Individual fine fescue cultivars– Organic and synthetic fertilizers– No irrigation, wear applied
• Highest quality improved Chewings, Mixture of improved cultivars of fine fescues
• Fine fescues better under drought• Organic maintained higher fine fescue, faster divot recovery
with synthetic

Why overseed with different species?
• Use mixtures for genetic diversity
• Resistance to diseases and stresses
• Color contrast
• Improved transition
• Improved quality
• Smaller seeds
• Potential cost savings

Improving Turfgrass Through Research
Outlook for 2006-7
*Anticipate average yields, but low carryover and strong demand will keep the fine fescues in tight supply.
*Limited supply of the newer varieties.
-SR 5250 strong creeper
-SRx55R slender creeper-(very limited)
-SR 5130 Chewings fescue
-SR 3210 blue fescue
-SR 3150 hard fescue
*Prices should remain firm with some potential upside. Canadian creeper prices are up.
