Plant protection products are applied to farmed land to protect crops from harmful organisms. From there, they might be transported via drift and run-off to adjacent habitats. For the active substances, regulatory acceptable concentrations (RAC) for aquatic organisms are determined during the authorization process. As part of the process of assessing the environmental risk, these RAC values are compared to predicted environmental concentrations in surface waters. If the result of this comparison indicates that the risk for aquatic communities is too high, specific measures to reduce the risk will be taken. In order to protect surface waters from potentially harmful substances, buffer strips between the site of application and the threatened habitat will be specified. By using technical measures such as anti-drift nozzles and/or vegetation barriers, it is possible to further reduce the drift from the farmland. If these substances are applied according to the regulations, there will be no adverse side-effects for the environment.
Grass-based beef production is markedly less productive than intensive year-round indoor-housing system-based production. Agroscope experts therefore studied how grass-based farms can produce both economically and in an ecologically sound manner.
Orchard crop spraying using unmanned aerial spraying systems commonly referred to as drones can lead to drift, posing a risk to residents and bystanders. The study shows that the risks arising from this are taken into account by the current registration process.
Trials conducted by FiBL have shown that conversion to organic farming also promotes endangered Red List species such as the carabid beetle species Amara tricuspidata. This species and other species consume seeds of forbs and grasses and thus supports natural weed control.
