For water protection in agricultural areas, Crop Science recommends the use of biological remediation systems such as Phytobacª. This system is designed to prevent water contamination with residues of crop protection chemicals generated during the filling and cleaning of spraying devices or the disposal of residual liquids. The system is used in many E.U. countries and offered commercially by various suppliers. More than 4,600 remediation systems are currently in operation in Europe. Projects to introduce the system have also been implemented in Australia, Canada, China, Thailand and Latin America (Argentina, Brazil and Colombia). Together with external partners we are developing a digital geoinformation system for agriculture in order to protect neighboring water bodies from contamination with crop protection products. Site-related risks are visualized by means of high-resolution maps supplemented with risk mitigation proposals.
