Fusarium Patch is common primarily on shady greens or greens subject to long dew periods during fall and winter. Under Northwest conditions Penneagle performs poorly on putting greens due to lack of vigor and is most often used on tees. Penncross was much more vigorous than Seaside, had better summer performance, and produced both good putting turf and good fairway turf. Selections of superior types of creeping bentgrass from original plantings of South German mixed bentgrass led to development of the C series bentgrasses at the Arlington Turf Gardens in Virginia (6). Bill Meyer, Stacy Bonos, and Virginia Lehman. Creeping bentgrass can tolerate a range of cutting heights to suit a golf or bowling green e.g. palustris Pers. Burton.

On our experimental green we have not had to apply fungicides on Providence creeping bentgrass in any of the last five winters. Preparation of the turf bed is extremely important. The most common strategy used on golf courses involves frequent irrigation at slightly less than ET, supplemented with hand watering to maintain dry firm conditions during the growing season. Creeping bentgrass (agrostis palustris) was originally cultivated for use on golf course greens. In recent years, intense breeding and selection work has resulted in a flood of new cultivars with widely varying characteristics and generally much improved surface quality. Creeping Bentgrass – Agrostis stolonifera Many commercial farms have problems with creeping bentgrass ( Agrostis stolonifera ), which causes pasture stands to become matted.

On that green we routinely see no more than 5- 15 spots over the course of the winter. Thatch build up is largely due to stolon development and the slow decomposition rate of thatch in a sand rootzone. The newer super dense and super fine creepers appear to be more competitive at very low heights but we have too little experience to say with certainty that they will exclude annual bluegrass in the long run. Remove debris and rocks and rake out the bed to grade it and break up clods. In September of 2008, 23 bentgrass cultivars and selections were established from seed at the Joseph Valentine Turfgrass Research Center in University Park, PA, as part of a five-year NTEP test. Optimum N- P2O5-K2O-S ratios appear to be in the range of 6-1-4-4 and target rates of N should probably be around 0.25 to 0.5 lb N/1000 sq ft per growing month. Our research determined that cultivar selection plays a role in early-season germination and should be considered before overseeding into winterkill areas. Every single bent strain in T-1 was tested against Poa annua, so much so that T-1 makes visible gains against Poa annua each year.T-1 sets a new standard for bentgrass tiller density, providing a rich, smooth putting surface.
