Risk mitigation measures for Pesticide Runoff - How effective are they?

Both vegetative filter strips and micro-dams are effective and suitable and can therefore be recommended for quantitative assessment of environmental pesticide exposure in surface waters. However, the processes of infiltration and sedimentation in vegetative filter strips should be simulated with a mechanistic model like VFSMOD. The reduction effect of micro-dams can be modelled by reducing the runoff Curve Number, e.g. in PRZM. Soil conservation measures are in principle promising, but further well-documented data are needed to determine under which conditions they are effective. This article is protected by copyright.
