Improving Turfgrass Through Research
Tall Fescue Strategies
• High turf quality, rapid establishment
• Rhizomes - Advertise and promote XRE
• Higher percentage of plants with rhizomes
• More rapid rhizome production
• Verification of rhizomes in mown turf
• Brown patch
• Screening at multiple sites - remove survivors
• Screening progeny from drought / rhizome work
• Drought tolerance and recovery - 3 cycles GA
• Salt tolerance

Use this slide if you are going to use a picture. To
make a presentation interesting, you should have
images on at least 50% of the slides. Without visuals,
you will quickly put people to sleep. You might
anyway, but you have a better chance of keeping their
attention if you use some nice visuals. Pictures can
make the presentation look more professional.
Delete this text and place picture in same area, lining
picture up with top of yellow text.
Use 72dpi jpgs images.
To shrink picture proportionally once it’s on the slide:
1. Click on the picture (note corner handles).
2. Hold down the Shift key, then press and drag a
corner handle towards the middle of the picture.
3. Release the Shift key first then the mouse.

•
Weaknesses
– Bunch-type growth
– Speed of repair slow
– Rhizomes in new varieties may help
– Need more winter-active growth
– Brown patch susceptibility - in enclosed shade can
severely damage
– Old cultivars lacked density and texture, new
cultivars finer textured, darker green, higher
density

•
How to use
• Best results when blended with Kentucky
bluegrass - 85 to 90% Tall fescue
• Blending with Texas x Kentucky hybrids may be
useful in stress sites
• Brown patch reduced in blends
• Establish in spring or late summer
• Provide protection against Pythium and seedling
brown patch
