报告简介:

Plant protection products and biocides can be transported from treated fields to surface waters via surface waters during rain events. Potential risks for aquatic organisms due to surface waters are assessed during the registration process for Plant protection products and biocides, and risk mitigation measures are implemented if necessary. Currently, a vegetated buffer zone of 6 m width may be required as risk mitigation measure for surface waters. Further options for risk mitigation of surface waters that can be linked to Plant protection products and biocides registration were evaluated at Agroscope on behalf of the Swiss Federal Office for Agriculture. These options should effectively reduce the contamination of surface waters while minimizing impacts on agricultural productivity. The list of mitigation measures resulting from this project offers farmers the possibility to combine those measures that are best suited for their particular situation or those that are already implemented for other reasons (e.g., for erosion control). Besides vegetated buffer zones, these include e.g. conservation tillage, vegetated strips within the field and use of cover crops in orchards and vineyards.
