The Fine Fescues

Festuca sp.

Introduction:

The fine fescues are composed of several different Festuca species and subspecies. All are fine textured compared to most other commonly planted turfgrasses. Fine fescues have long been used in mixtures with other grasses and are generally considered the standard for shade tolerance in cool season grasses. In recent years, the fine fescues have received attention as low input environmentally sustainable grasses. Most retail lawn mixtures contain at least some fine fescue.

Low Maintenance Turf?

Low Maintenance Turf?

What is a low maintenance lawn? Who sets the standards? An honest answer to both of these questions is probably "I don't know". By my standards most people in western Oregon already have low maintenance lawns. Their lawns are mowed sporadically in spring, occasionally in summer and fall and not at all in winter. A clear majority don't irrigate at all and of those who do, few irrigate consistently. Perhaps seventy percent of these homelawns are never fertilized and very few are ever treated with herbicides for weed control. Sounds pretty low maintenance to me.

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.

2008 Annual Bluegrass Fertility Trial

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.

Annual Bluegrass Fertility Trial 2006-2008

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:

Reduce or Eliminate Fall Watering

As I drove into campus this morning, I noticed several sprinkler systems running.  After a week of on and off rain, day temperatures in the 70s and night temperatures in the 40s, it is time to reduce watering times and/or days or even better, turn the irrigation system off.  The turf is using very little water this time of the year and it will allow the turf to naturally harden off as the winter months approach.  An additional benefit of turning your irrigation system off is that the lack of moisture will greatly reduce the survivability of European Crane Fly eggs.  So, turn the irrigation

Roundup Tolerant Tall Fescue/Perennial Ryegrass Trial

Introduction:

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.
