Reducing brown ring patch severity on Poa annua greens
نویسنده
چکیده
We have conducted joint research studies on the management of brown ring patch since 2010. From a feld research perspective, this disease has been challenging to work with because it is diffcult to fnd naturally infected putting greens with uniform disease incidence and severity. The main body of research presented in this paper comes from work conducted in 2010 and 2011 on a putting green in New Jersey that exhibited an unusually uniform distribution of brown ring patch symptoms. Additional data were obtained in 2012 and 2013 from smaller research trials on putting greens in Pennsylvania with less severe disease pressure. Brown ring patch has become an important disease of annual bluegrass (Poa annua) putting greens in the Northeastern region of the United States since 2007 (6).

The plant-endoparasitic nematode Anguina pacificae is presently one of the most destructive pests of Poa annua in Northern California, causing stem galls at the base of tillers in this annual bluegrass, resulting in yellow or brown patches and irregular surfaces on golf course putting greens. The objective of the study was to investigate the population dynamics of A. pacificae on two golf cours...

It is common fallacy in Britain that 'American' golf greens are constructed of sand; are excessively irrigated, excessively fertilized, and that their surfaces are soft. Generalisations of 'American' golf greens cannot be made. The diversity in climates, maintenance budgets, construction methods, etc., results in a host of 'American' greens. The grass species on the greens may consist of Poa an...

Anthracnose is a destructive disease of weakened or senescent turf caused by the fungus Colletotrichum cereale. The disease occurs throughout the world on almost all turfgrass species but is particularly severe on annual bluegrass (Poa annua L.). It has been suggested that management practices commonly employed on golf courses may be enhancing abiotic stress and thus predisposing turf to anthra...
