Course information provided by the Courses of Study 2020-2021. Courses of Study 2021-2022 is scheduled to publish by July 1.

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, symptomotology, 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.
