The ACP concluded that IPU could continue to be used, subject to some restrictions on its use which are shown in Table 2. MAFF recommended that pesticides were not the only weapon against blackgrass and that cultural control methods, such as changing cultivation techniques and rotations could also help reduce blackgrass populations. Other recommendations withdrew the previous approval for using IPU before the crop had emerged (pre-emergence) and applications from the air. A product ‘Stewardship’ Campaign is being initiated by the IPU Task Force (a group of IPU manufacturers), including a leaflet on how to protect water quality.

An EQS is the concentration of a substance which must not be exceeded within the aquatic environment in order to protect it for its recognized uses. EQSs are specific to individual substances (including some pesticides) and are produced using the best available environmental and ecotoxicological information. Currently, EQSs only relate to surface water. Statutory EQSs have been set in legislation by the European Commission (EC) and in the UK by the Department of Environment (DoE).

Diuron, however, is found more frequently in marine waters, probably as a result of its use in antifouling paints.
