John regularly consults with government and the EU on development and implementation of policy on monitoring and eradication of quarantine bacteria.
John is a member of the EPPO panel on diagnosis of plant pathogenic bacteria and a founding member of the European Association of Phytobacteriologists. He is currently managing research projects on bacterial pathogens of potatoes (Pectobacterium spp. and Ralstonia solanacearum), tomatoes (rhizogenic Rhizobium radiobacter) and mushrooms (Pseudomonas tolaasii and P. gingeri) as well as understanding the biological diversity of soils in relation to plant health and productivity.
Potatoes are just one of the crops the Fera crop health team can test for problems.
