An algorithm was developed for use in a geographic information system (GIS) to model the surface movement of herbicide in response to a rainfall event as modulated by slope, soil, management practices, and time of herbicide application. This algorithm was implemented in the GIS software Geographic Resource Analysis Support System (GRASS) and uses a...

... The ability to predict the distribution of weeds with a certain level of accuracy could lead to site-specific management (Wiles and Schweizer 2002;Wyse-Pester et al. 2002). GIS have also been used to model herbicide movement, map pesticide leaching potential, forecast impact of climate change on invasive plants, and predict distribution of invasive weed species in non-cropland habitats based on spatial variables (Hornsby 1992;Jarnevich et al. 2010;Mitchell et al. 1996;Vanderhoof et al. 2009). This type of analysis could also be useful in identifying spatial and temporal trends of problem weeds on a larger scale in agricultural production (Kalivas et al. 2012) but is often limited by a lack of geospatial data on weed distribution (Mueller-Warrant et al. 2008). ...
