Abstract

Horseweed (Conyza canadensis) with evolved glyphosate resistance (GR) has become an especially problematic weed in crop production across the United States. This paper reports on the framework development of an Internet decision tool that can be used by regulatory agencies, industries, farmers, and the public. It estimates the potential gene flow from GR horseweed and can offer guidelines for the prevention of gene flow under different meteorological and environmental conditions. The online tool is based on the Lagrangian dispersion model Hysplit4.0 which simulates local and regional dispersion, deposition, and outcrossing of horseweed pollen and seeds. The tool has user-friendly "Googlemap" interfaces.
