This major international conference, the sixth in an ongoing series, will review new research on the origins, nature, development and prevention of resistance to insecticides, fungicides and herbicides. It will provide a forum for researchers, consultants, regulators and industrialists to present and discuss approaches to overcoming this continuing and important constraint to effective crop protection. Themes will include: the current status of resistance to pesticides, resistance mechanisms, population biology and modelling, applications of genomics, risk assessment and regulation and transgenic crops.
