Weed Science


The Weed Science Program develops educational programs and conducts applied research in weed biology and management for growers of vegetables, grapes, turf, and ornamentals in the field, containers, and in the landscape.

Purpose

Growers and end-users of horticultural products are constantly confronted with potential loss of quality and economic value due to weed competition. Additionally, great concern about the potential contamination of the single source aquifer from which Long Island draws its drinking water has resulted in a desire to reduce pesticide use. The weed science program is continually evaluating new and alternative weed management methods to address these issues.

Program Summary

  • Applied Research: Investigate both traditional weed control approaches and alternative and cultural methods to address weed management problems through research.
  • Educational Extension: Disseminate information through articles in trade journals, illustrated lectures, fact sheets, weed identification gardens, and website contributions.
    Contributing authors to several publications including two of the Cornell Pesticide Management Guides, for Commercial Production of Trees and Shrubs and for Production and Maintenance of Herbaceous Perennials.
  • Advisory: Advise legislative and municipal agencies such as the New York State Department of Transportation and the Long Island Invasive Species Management Area, a consortium developing an invasive species management plan for Long Island.
