2007 Evaluation of timing and number of fungicide applications for  control of A

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.

2007 Evaluation of Fungicides and Fungicide Programs for the  Control of Anthrac

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.

2008 Evaluation of Turf Phytotoxicity and Quality of a “Providence” Creeping Bentgrass Putting Green Resulting from Multiple Applications of Proxy, Primo, & Trimmit Growth Regulators

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.

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.

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.

2008 Annual Bluegrass Fertility Trial

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.
