Course information provided by the Courses of Study 2019-2020.

This course examines components of the biology, ecology, and management of weeds in crop and non-crop ecosystems, particularly in the Northeastern United States. The first part of the course focuses on biological/ecological factors that govern seed dormancy, plant growth, population dynamics, competitiveness, reproduction, and survival. Close attention is given to accurate identification of plants and to characteristics that make weeds competitive, undesirable, or both. The second part of the course examines strategies to control weeds, including  their benefits and drawbacks. Aspects of chemical control, including classification, mode of action, selectivity, symptomology, and resistance, are presented. Herbicide-tolerant crop (i.e., GMO) issues and health and environmental concerns of herbicide use are addressed. The use of integrated approaches to weed management is emphasized. 

When Offered Fall.

  • Identify the different life stages of at least 90 weed species commonly found in the Northeastern United States and southern Canada.
  • Identify and describe the major biological factors and ecological principles that influence weed growth, population dynamics, invasiveness, and survival.
  • Describe the various strategies currently being used to control and/or suppress weeds in different crop and non-crop systems.
  • Identify the classification, mode of action, selectivity, and symptomology of commonly used herbicides.
  • Calculate and apply the appropriate amount of a given herbicide that is required to treat a specific area using a backpack sprayer.
  • Appreciate the diversity and impact that weeds have in different ecosystems.
