Curriculum Vitae and research interest in short

Jürgen Köhl is focusing his research on sustainable solutions ensuring plant health. His main topics are the biological control of fungal plant pathogens using antagonistic fungi and methods for disease prevention. Understanding disease epidemiology often is a first step in such studies. During the last years, he worked on disease management in pome fruits, cereals and vegetables with emphasis on leaf and fruit diseases. He screened new antagonists for biological control apple scab, Fusarium head blight and powdery mildew. Epidemiological studies focused on the life cycle of pear brown spot, storage diseases in pome fruit and black spot disease in carrots.
Currently, he is coordinator of EU FR7 project BIOCOMES ( and convener of the IOBC-WPRS working group ‘Biological and integrated control of plant pathogens’. His institute at Wageningen University & Research is a private not for profit research institute specialized in strategic and applied research for industry and public institutions. He is also member of the Faculty of Agriculture, Rheinische Friedrich-Wilhems-Universität  Bonn, Germany since his habilitation in 2003.

Presentation title

The challenge of developing microbial biocontrol products for disease control

ABSTRACT - Commercial biological control products for the use against plant diseases must be highly efficient against the targeted diseases. However, the used antagonists have to fulfil a broad range of additional requirements regarding market sizes for the envisaged products, ecological characteristics and production costs of the antagonists, safety, toxicological and eco-toxicological risks and protection of intellectual property rights. Consequently, a broad range of criteria has to be considered during the selection of new antagonists. Screening programs can use a stepwise approach to assess candidate antagonists for this broad range of criteria in order to exclude unwanted candidates in an early stage. Essential decisions at the beginning of new screening programs are to collaborate with biocontrol industries from the beginning, to include relevant commercial questions early during the screening program and to combine the expertise in plant pathology with expertise in biotechnology, agronomy, microbiology, toxicology, registration, marketing and product development. Examples of screening programs for the development of new biocontrol products against apple scab and powdery mildew ( will be discussed.
The project BIOCOMES has received funding from the European Union’s Seventh Framework Programme (grant agreement 612713).
