Microdochium Patch Fungicide Control Strategies
August 15, 2010

Avoiding Buildup of Resistant Fungi

  • Most failures are probably not due to fungal resistance to fungicides.
     
  • Fungal resistance is most likely to develop where you over use systemic fungicides and don’t alternate modes of action.

    Examples in the PNW on Microdochium Patch: Clearys 3336, Chipco 26GT, and Heritage.
     
  • Pathologists have numerous theories on the best strategies for managing fungicides to avoid resistance.

Efficient Lawn Irrigation in the Intermountain West
October 11, 2010

Introduction

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).

Fertility Management for Annual Bluegrass
October 30, 2007

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.

Thatch Management
January 1, 2008

Thatch is a layer of organic material between the green grass and the soil. Thatch is composed of living and dead stems and roots. Leaves make up only a very small percentage of thatch. Sometimes leaves will form a layer of pseudo thatch at the juncture of the thatch and the green grass. It disappears quickly.

Vegetative Identification of Common Turfgrasses in the Pacific Northwest
January 1, 2008

Identifying lawn grasses requires a basic knowledge of plant structure and the ability to distinguish between those structures to categorize specific grasses. To get really good at identifying turfgrasses you have to learn the characteristics of the common grasses.

European Crane Fly
February 1, 2008

This is an unusual insect in that it causes most of its damage in late winter and early spring as larvae feeding on all parts of the plant. While we think of it as a turfgrass pest it is also active on many ornamental perennials. The historical pattern for this insect is to move quietly into an area where it may develop to very high populations within a year or two.

Annual Bluegrass , Poa annua L.
February 1, 2008

Revised Feb. 2008

In nature, annual bluegrass, Poa annua L. behaves as a true annual. It germinates in fall or spring when moisture is adequate and develops quickly, often flowering six to eight weeks after germination. In the Pacific Northwest we see it most commonly as a winter annual (Fig 1). After flowering and setting seed these annual types die typically from drought and leave dormant viable seed behind to germinate when moisture again becomes available. This efficiency in seed production makes annual bluegrass a major component of the seed bank of cultivated soils.

Turf Adaptation & Ecology Part 2: Turf communities in Western Oregon
January 1, 2008

Turf adaptation implies that commonly planted grasses have specific climatic conditions in which they thrive. Therefore, if we know the climate we should be able to predict what grasses will have a reasonable chance to prosper. The converse is also true. If we plant grasses in climates where they are not adapted, we can expect to have problems growing a healthy lawn. One way to depict turf adaptation is through maps.

Creeping Bentgrass
February 1, 2008

Introduction:

For as long as golf has been played in the Pacific Northwest creeping bentgrass has been planted on putting greens, first as a component of South German mixed bentgrass, and later as seeded or stolonized varieties. In recent years, intense breeding and selection work has resulted in a flood of new cultivars with widely varying characteristics and generally much improved surface quality. While early creeping bentgrasses quickly gave way to annual bluegrass, newer cultivars are much more competitive and may prove to be much more persistent.
