The purpose of this trial was to evaluate the effectiveness of repeated applications of various formulations of chlorothalanil at two rates, Tourney 50, and two fungicide rotations in controlling dollar spot (Sclerotinia homoeocarpa) on a colonial bentgrass (‘Bardot’)/annual bluegrass fairway.
Ten years of research into microdochium patch disease.
The purpose of this trial was to evaluate the effectiveness of various fungicides in controlling Microdochium patch on a bluegrass green.

The purpose of this trial was to evaluate the effectiveness of various fungicides and fungicide rotations in controlling anthracnose (Colletotrichum cereale) and maintaining plot quality on an annual bluegrass (Poa annua) putting green.
Practical strategies for the renovation of turfgrass, used to improve existing turf or change grass species for improved performance. The basic strategies discussed include simple overseeding, overseeding following suppression of existing turf, and complete renovation.

Maintaining a healthy, aesthetically pleasing lawn depends on many variables including turfgrass species; mowing height and frequency; fertilization; and insect, disease, and weed control. Proper irrigation, despite being one of the most important factors in maintaining a healthy lawn, is the most often overlooked variable in lawn care (figure 1).

We are looking for a site to do a fairy ring control trial in 2011.
If you are having consistent problems with fairy ring and are willing to allow plots to be set up and different fungicide treatments applied, please call Brian McDonald at 541 231-1149. The ideal site would be about 2,000 square feet with uniform fairy ring symptoms throughout. The area could be a golf course fairway, rou

Describes necrotic ring spot disease and methods of prevention and control.
Explains how to optimize a fertilization program for a home lawn. Discusses how to select and use fertilizers, the roles of various elements (nitrogen, phosphorus, potassium, sulfur, pH, calcium, magnesium, and iron) in lawn fertilization, and the value of soil tests for each element. Provides sample calendars of necessary and optimal times for fertilizer applications for western, central, and eastern Oregon.
Putting greens in Oregon range from 80% to almost 100 % annual bluegrass. The reality of golf course maintenance in the Pacfic North West is that annual bluegrass will eventually dominate turf on tees, greens, and fairways.
