Bentgrass Trials Combine different species and types one trial Differential herbicide/fungicide response Different requirements for thatch control NTEP Trials at Universities - United States National Turfgrass Evaluation Program - www.ntep.org Most not managed as on golf course Less mowing, mowing height different No traffic More trials this cycle with no or reduced fungicides Fairway and Greens trials - Greens trial on soil and sand Some varieties in only one trial due to seed availability

Bentgrass Trials Management influences - Four sands / One cultivar

Creeping bentgrass Standard varieties - Lower density, horizontal growth Seaside, Penncross, Penneagle, Pennlinks Improved varieties - Moderate density for greens, tees and fairways : Providence, SR 1020, Crenshaw, Seaside II, Trueline, Backspin, Putter, Cato, Century, Princeville, Cobra, Viper, Grand Prix, Bengal, Mariner, Regent, Imperial, ProCup, Southshore, 18th Green More upright, versatile Less thatch for fairways Disease and stress resistance important characteristics for selection

Creeping bentgrass Improved - Moderate high density for greens, tees and fairways SR 1150, SR 1119, Brighton (SR 1120), Sandhill, Ninety-six two, L-93, LS-44, Alpha, Independence, Bengal, Penneagle II, Pennlinks II, Benchmark DSR, 13-M Higher density than older cultivars - Upright growth Slightly more potential for thatch - watch fertility Most moderately fine texture Select for important disease resistance, color, stress tolerance

Creeping bentgrass Versatile varieties - High Density for greens, tees and fairways 007 (DSB), MacKenzie, Memorial, Kingpin High density but with upright growth so more versatile Low tendency for Bentgrass Bloat - scalping Slightly greater thatch management needs Low Poa annua invasion May be combined with Ultra for greens or improved types in fairway blends

Creeping bentgrass Ultra varieties - Very high density - greens Tyee, Authority, T-1, Shark, CY-2, Declaration - new ones this type Penn G-2, G-6, A-1, A-2, A-4, G-1 - all from selections at Augusta, GA - very similar genetics Some high thatch producers - must have budget and equipment to control, some newer upright growth Slower repair aerification holes, ball marks Use smaller diameter holes, topdress frequently Upright, dense growth - good at low height Good wear tolerance

Creeping bentgrass Divot repair rate Variable by cultivar - Penncross not fastest despite reputation Cover may be greater but not fully repaired Higher density varieties sometimes ballmark less but some recover slower All bentgrasses - use sand/seed repair mix Add Chewings fescue into repair mix for faster germination Waiting for 6 weeks to grow in for repair = Poa annua

Percent repair after 6 weeks 1998 Creeping bentgrass Damage control study Clemson, University Repair of damage from 2 inch hole in June and August Repair rate differed by type - standard and improved typically better than dense.

Bentgrass Strategies Dollar spot resistance - New Michigan State, WI germplasm Stress tolerant - germplasm from AZ with salt and heat tolerance + improved winter color Dense types without excessive thatch Improved varieties to blend with current stable Salt tolerance Snow mold resistance for northern areas

Kentucky Bluegrass Types Dr. Leah A. Brilman

Kentucky Bluegrass Strengths Self-repairing High lateral stability High recuperative ability Dense stand, high quality Excellent mowing quality High cold tolerance Some cultivars with improved drought tolerance Select a blend of types depending on use

Kentucky Bluegrass Weaknesses Poa annua invasion - less options in herbicides - new ones coming on market Slow germination and establishment - heavier seeding rates better Shade tolerance cultivar dependent Bluegrass billbugs Must mix cultivars carefully - use different types to match strengths and weaknesses Not adapted to some regions

Kentucky Bluegrass Types Compact Types CELA Type Compact BVMG Type Midnight Shamrock type America Cheri Type Aggressive Type Julia Type Bellevue Type Common Type Mid-Atlantic Type Other Type

Kentucky Bluegrass Types These types have been verified by DNA analysis Cultivars in most types are closely related genetically Often no or very small DNA differences If planting all of one type = all of one cultivar Greater DNA differences in Aggressive / Mid-Atlantic types - based more on performance Performance strengths and weaknesses are the same within a type

Why Blends and Mixtures Kentucky bluegrass apomictic Cultivar = Single genotype - other turfgrass species are mixture of genotypes Vegetative cultivars comparison Vegetative bentgrasses Vegetative bermudas, zoysias, St. Augustine Merion Kentucky bluegrass - stripe smut Not just for disease resistance

Blending bluegrasses Kentucky bluegrass Melting-out resistance of blend of two cultivars intermediate between same cultivars in monostands Inoculum from susceptible cultivar reduced resistance of resistant cultivar Blends of two cultivars generally show resistance intermediate between each alone (Vargas and Turgeon, 1980. Proc. Third ITRC 45-52.)

Blending bluegrasses Early blend analysis - Dr. Funk, Rutgers Sprigged out plants to ID Aggressive types dominated Aggressive types based on invasion in plots New DNA techniques allow blend analysis (Lickfeldt et al, 2002. Crop Sci. 42:842-847.) 3-way blend - Unique, Midnight, Blacksburg Different management and % of each at seeding Final composition, 40% U, 46% M, 14% B

Blending bluegrasses Why combine types in blends? Each type has weakness as well as strengths Single type has weaknesses Midnight types - powdery mildew, winter color, rust susceptibility as seedlings America types - not as dark green Aggressive - dominate in blends Shamrock types - billbug susceptible BVMG - Very stemmy turf, poor winter performance, stripe smut susceptible

Conclusions Blends do provide benefit Learning long term blend peformance Kentucky bluegrasses difficult to breed Cooperative work breeders and NTEP to define types and publish Looking at competitiveness in different environments and management Never use more than 15% perennial ryegrass to maintain at least 50% bluegrass

Kentucky Bluegrass Types NJ Wear - Spring, summer and fall wear (multi - use field) High performers Low performers Compact America Midnight BVMG Julia Cheri Aggressive Common Mid-Atlantic Repeat with wear, compaction different seasons

Kentucky Bluegrass Types WI Wear trial - fall wear Combined with perennial ryegrass varying percentages Only obtained 50% KBG with less than 15% rye No difference between Midnight types, BVMG types, Aggressive types Common types less wear tolerant Midnight, Fairfax more dominant in blends

Compact Types Compact, Midnight, America Low, compact growth High quality turf 1/2 inch cutting height Excellent resistance to Leaf Spot Long Winter dormancy Variable under Summer stress Often purple Winter color
