Introduction
The purpose of this trial was to evaluate different timing intervals of fungicide applications necessary to control anthracnose (Colletotrichum cereale) on annual bluegrass fairways. Three products were evaluated combined with and without Daconil Ultrex: Cleary’s 3336, Cleary’s 3336 Plus, and Banner Maxx.

Overview of the presentation by Brian MacDonald
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.
The purpose of this trial was to evaluate the effectiveness of various fungicides and fungicide rotations in controlling anthracnose (Colletotrichum cereale) on an annual bluegrass putting green.
Tom Cook, retired OSU turfgrass professor, has published a new book detailing the construction and maintenance of sustainable landscapes! The book includes topics such as sustainable landscape design, how to develop an ecosystem, issues regarding the use of chemicals, and approaches for modifying existing lancescapes.

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).
The purpose of this trial was to evaluate a single preventative application of various fungicides for the control of gray snow mold on a golf course fairway.
The trial was initiated on October 23rd (after the last mowing) on the 11th fairway of the Meadows Golf Course (4,160 feet elevation) located in the Sun River Resort in Sun River, Oregon, 15 miles south of Bend.
The purpose of this trial was to evaluate the effectiveness of various fungicides and kelp in controlling anthracnose (Colletotrichum cereale) on annual bluegrass putting greens.
The purpose of this trial was to evaluate the effectiveness of various fungicides in controlling Microdochium patch (Microdochium nivale) on an annual bluegrass putting green.
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
