Anthracnose

Anthracnose is a serious disease of Annual bluegrass (Poa annua L.)and Creeping bentgrass (Agrostis stolonifera).  The pathogen now known as Colletotrichum cereale, was formerly known as Colletotrichum graminicola.  Although related to some degree anthracnose is associated as either a foliar blight or a basal rot.

Factors that Influence Golf Ball Lie

The golf ball lie is critical to determining the playability of golf course fairways and roughs.  The common definition of golf ball lie is the amount of the golf ball that remains above the turfgrass canopy after the ball comes to rest.  A ball lie where it sits above the canopy produces a clean hit imparting backspin on the ball.  In situations where the ball may sit down into the canopy leaf blades can become the club and the ball causing the ball to “fly” upon being struck imparting little backspin.

 

Classic Golf Hole: The Redan Hole

The Redan hole is one of the most famous, and complex Par 3 designs in golf. Named for a fortress mainly constructed from earthworks, the original Redan hole is the 15th hole at the West Links of North Berwick in Scotland. The design of the hole is credit to the greenskeeper at the time David Strath (1876-1979).

 

Topdressing High Shoot Density Putting Greens

Sand topdressing helps control/dilute organic matter accumulation on putting greens.  The popularity of high shoot density creeping bentgrass (ex. Penn “A4”, Alpha, etc.) and bermudagrass ultradwarf (ex. Tifeagle) varieties make the incorporation of topdressing into greens difficult.  The inability to incorporate can result in much of the topdressing being removed by mowing.  Additionally, mower blades loose their sharpness resulting in poor mowing quality.
