Plant Pathologist

Biointeractions and Crop Protection


Bart leads the fungicide research team that has been studying mechanisms for fungicide resistance using the latest advances in phenotyping and genomic tools. The information gained from this work has been used to devise strategies for an optimal, more sustainable disease control while minimising the risk for fungicide resistance development using appropriate crop protection inputs, agronomic practices and host resistance (IPM). There are several current research aims: 1) to understand how control agents work (mode of action of new active ingredients, plant defence activators and biocontrol agents) and to identify potential mechanisms employed by pathogens enabling them to cope with such agents; 2) to develop molecular tools/diagnostics to understand the role of inoculum sources (seeds, stubble and alternative hosts), to study the epidemics of fungal diseases and to monitor the evolution of specific traits in pathogen populations (fungicide resistance and virulence factors); and 3) to evaluate novel strategies for disease control and fungicide resistance management in commercial crops. Bart is also a member of the UK Fungicide Resistance Action Group (FRAG-UK), a forum to discuss and promote practical guidance on the status and management of fungicide resistance issues in the UK.
