    2000 WCTA RESEARCH PROJECTS
     
    Characterization of Leaching at the Coeur d'Alene Golf Club Floating Green
    (3rd year of three years). Dr. Bill Johnston, Washington State University, Pullman.

    Objectives: 1. Quantify water flow and movement of NO3 and NH4 through a large-scale sand-based putting green under actual golf course field conditions; 2. Demonstrate the effect of N fertilization and application methods on sand-based putting greens to promote environmental safety and support the highest level of turfgrass quality. This research projects is in cooperation with the USGA Green Section, Northwest Turfgrass Assn., Inland Empire GCSA, Oregon GCSA, Peaks & Prairies GCSA and the Western Washington GCSA.
    Total yearly value: $36,000 US ($54,000CDN)
    WCTA: $7,500 ($5,000 US).

    Controlling Winter Disease with Fall Applications of Potash
    ( 2nd year). David Sullivan, Castlegar Golf Club.

    Objectives: To analyze the effectiveness of different rates of potash applied on fairway turf subsequent to aerification with product broadcast dry on the turf surface. Data will be collected on the effects to the control of pink snow mold and grey snow mold.
    Total yearly value: $3,000
    WCTA: $2,000.

    Increasing O2 Levels and Decreasing Anaerobic Conditions in the Rootzone on Sand Based Turf
    (1 year). Peter Szarka, The Redwoods Golf Course.

    Objectives: To increase the O2 levels and decrease excess CO2 and H2O levels in the root zone of a USGA specified green mix. A Sub-Air unit will be attached to the drainage system to vacuum out sub soil gasses thereby drawing fresh air into the root zone.
    Total yearly value: $13,500
    WCTA $6,500.

    Development of an Integrated Management System to Reduce Earthworm Casting on Golf Course Fairways
    (3rd year of 3 years).

    Objective: To reduce worm castings on golf Course fairways by limiting earthworm casting activity. The initial investigation focuses on identifying which species are present and learning more about the biology of there earthworm species that cause casting problems in western Washington, Oregon and Canada. Second, to evaluate several cultural practices that have been shown detrimental to earthworm activity in previous research in other regions of the world; and to incorporate these cultural practices into a management system specific to the conditions and earthworm species present in the northwest.
    Yearly Value: $23,700US ($35,550CDN)
    WCTA: $7,500 ($5,000US)

    Pest Poster for Turf Maintenance Facilities
    (1 year)
    Leslie MacDonald, BC Ministry of Agriculture and Food is editing pictures and information for a poster to be displayed for employees to have picture ID to recognizing pests and pest damage.

    Total yearly value: $4000
    WCTA $3000

    Evaluation of turfgrass quality, thatch development and rooting environment of Poa reptans under different thatch management regime
    (1st year of two year project). Bently Sly, Northlands GC and Dr. Brian Holl, Lamorna Enterprises.

    Poa reptans has only recently been introduced to the turfgrass market and there is little information available on management of this particular species on an active golf course. This project is designed to address management of Poa reptans specifically with respect to the development of thatch, as well as to begin to develop our knowledge base of how this species performs in the Pacific North West.
    Total yearly value: $22,000
    WCTA $8,700

    Marine Glacial Clay for Control of Microdochium Navale
    (one year) Ray Benedetti, Fairview Mountain GC.

    To determine if Ocearic Marine Clay will control or prevent pink snow mold on fairways (poa annua and poa pratensis). Also to observe any nutrient benifits that the product may have. Ultimately, to determine if the product will be useful as part of an IPM program.
    Total yearly value: $3,000
    WCTA $1,000

    Action Plan for Defining Long Term Project to Minimize Pesticide Usage in Urban Canada
    Dr. Brian Holl Project manager.

    This project is the beginning to develop a national strategy to increase public awareness and usage of Integrated Pest Management techniques and to lay the foundation for significant reduction in pesticide usage in urban Canadian settings. Total yearly value: $20,000
    WCTA nil in 1st year

    Total Value: $ 155,050 CDN
    2000 WCTA Funding: $ 36,200 CDN
