Book now to avoid disappointment. 

Organised by Rothamsted Research and hosted at our headquarters in Hertfordshire, UK, the 8th International Meeting on Pesticide Resistance will cover the latest work on resistance to insecticides, fungicides and herbicides.

The programme will include talks, posters and presentations under three headings “Molecular Mechanisms and Genomics”, “Evolution and Selection” and “Monitoring, Field Studies and IPM”. It will bring together a wide range of academics, students, industry and stakeholder representatives to engage with the insights and strategies arising from the most up-to-date research.

This is always a popular meeting and spaces will be allocated on a first come/first served basis.


The registration fee of £350 including VAT will include attendance for the three days of the Conference, refreshments and lunch each day, an evening reception buffet dinner on the first evening, a Conference dinner on the second evening and a book of abstracts.
