Achievements of the WG ICOC

The emphasis of the working group has always been the networking of scientists working towards improved integrated pest and disease management of oilseeds, particularly the oilseed rape crop. Collaborative field experiments have been conducted on specific questions and joint projects established. Among these are included four large international projects funded by the European Union. These projects were conceived, are coordinated and executed mainly by members of the working group. These EU-Projects are:

Furthermore there have been 3 books published which can be related to activities among IOBC WG-ICOC members.
