Introduction
The first goal of this trial was to evaluate the effects of timing and number of applications on control of anthracnose (Colletotrichum cereale) on an annual bluegrass putting green.
A second goal of this trial was to determine the minimum number of applications necessary to produce acceptable turf quality.
Materials and Methods
Introduction
The purpose of this trial was to evaluate the effectiveness of various fungicides and fungicide programs in controlling anthracnose (Colletotrichum cereale) on annual bluegrass putting greens.
Materials and Methods
The trial was initiated on June 26th on an annual bluegrass putting green located at Emerald Valley Golf Club in Cresswell, Oregon. Subsequent fungicide applications were applied every 3 weeks on July 18th, August 8th, August 29th, and September 19th.
Preliminary Report
Objective
The primary objective of this trial is to determine whether repeated applications (2, 3, or 4) of Proxy (ethephon) or Proxy + Primo (trinexpac-ethyl) causes phytotoxicity to Providence creeping bentgrass maintained at putting green height. A secondary objective is to evaluate turf quality of putting green turf treated with Proxy, Proxy + Primo, or Trimmit (paclobutrazol) growth regulators. The Trimmit was applied at two rates alone and with additional fertilizer.

Purpose
The purpose of this trial is to evaluate one and two applications of various herbicides for the control of English Daisy (Bellis perennis) growing in lawns.
Materials & Methods
Final Report
Introduction
The purpose of this trial was to evaluate the sensitivity of four species of annual bedding plants to Mesotrione (Tenacity) herbicide. The initial treatments were applied 24 hours before planting. A second application was made six weeks later over the top of the plants.
Materials and Methods
Final Report - February 7, 2008
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.
NTA Final Report June 9, 2009
Purpose
By using balanced NPK + micros applied at a low rate (3.25 lbs N/1,000 sq ft/yr) or a high rate (6.5 lbs N/1,000 sq ft/yr), we are trying to determine if total annual NPK with or without added calcium, sulfur, or humates has any measurable impact on putting green turf quality, Microdochium patch disease, anthracnose disease, and/or turf species composition.
Note:
The information presented below is in the form of a progress report and all data are considered preliminary.
Purpose:
Using balanced NPK + micros applied at a low rate (3.25 lbs N/1000 sq ft/ yr) or a high rate (6.5 lbs N/1000 sq ft/yr), we are trying to determine if total annual NPK with or without added Ca, S, or humates has any measurable impact on turf quality, Microdochium patch disease, Anthracnose disease, and/or turf species composition.
Methods:
Previous work reported by Crystal Fricker at Pure Seed Testing Inc. demonstrated that it is possible to develop tall fescues and fine fescues that have relatively good tolerance to low rates of glyphosate. This trial is part of an ongoing effort to evaluate tolerance of tall fescues and other grasses to glyphosate at rates that are effective in controlling annual bluegrass.
