Abstract: Driven by concerns on the human and animal health and on the environment of the useof pesticides in the European Union (EU), the European Commission has launched a newlegislative framework, the so-called EU plant protection package, which will replace the hithertoexisting registration regulations of active substances and plant protection products. It consists offour parts: (1) The Regulation (EC) No 1107/2009 concerning the placing of plant protectionproducts on the market and replacing the Directive 91/414/EEC; (2) the Directive 2009/128/ECaiming to achieve the sustainable use of pesticides; (3) the Directive 2009/127/EC regarding tomachinery for pesticide application, and (4) the Regulation (EC) No 1185/2009 concerningstatistics on pesticide marketing and use. Whereas the Directives need to be converted into nationallaw in the EU member states, the Regulations are legally in force in all EU member states. Thisnew framework aims to harmonize the plant protection legislation in Europe and to developmeasures to reduce the risks posed from the use of plant protection products. As most biologicalcontrol agents (BCAs) underlie the same legislative procedures as chemical plant protectionproducts, these new regulations will also apply for most BCAs. Thus, they will have a strongimpact on future registration and use of BCAs.
