Many pesticides are soil applied, including residual herbicides, soil insecticides, and seed treatments incorporating fungicides and/or insecticides. Regulation within Europe is becoming increasingly stringent with regard to water contamination which is driving registrants to pursue novel means of application to reduce off-site movement of active ingredients. Simulation models are the primary basis for regulating pesticides against EU ground and surface water protection standards, but the current models cannot explicitly represent plants or their roots or the effects of formulations and formulation placement strategies (e.g., slow-release microcapsules and seed treatments). We present a new model of the soil/plant system to enable the environmental benefit of advanced formulations and placement strategies to be quantified in a cost-effective way for the first time.
