Weed ecology and management

Toni DiTommaso's research program investigates the basic biological/ecological principles governing agricultural and environmental weed population dynamics that ultimately lead to the development and implementation of safe, effective, sustainable and economically viable weed management strategies. To achieve this goal our research program comprises three major thrusts.

• Effects of the environment on weed species.
• Effects of weeds on their environment.
• Manipulation of the environment to suppress weeds.

Other content on this website developed by the DiTommaso Lab includes:

• Weed profiles - As co-author of the SARE publication Manage Weeds on Your Farm: A Guide to Ecological Strategies, DiTommaso contributed to these profiles that supply identifying and ecological characteristics, management strategies and references for more than 60 weeds.
• Weed ecology - Background on key concepts including seed longevity, dormancy, reproductive strategies etc. that help inform management strategies.
• Organic weed management - Enumerates multiple strategies fo manage weeds without herbicides.
• Herbicide reference - Describes modes of action, sensitive weeds, symptoms, crop/non-crop registrations and other information about common herbicides.
