Aims of the WG

To promote cooperation and exchange of knowledgebetween scientists and experts in the field of biocontrolof plant diseases and integrated managementTo promote the education for and implementation ofbiocontrol and IPM strategies in agriculture

• Biocontrol of Foliar Pathogens, EFPP, Taormina, Sicily,

Italy, Sept. 2000

• Biocontrol agents: modes of action and integration withother means of control, Sevilla, Spain, Nov.-Dec. 2000

• Influence of a-biotic and biotic factors on biocontrolagents, Kusadasi, Turkey, May 2002

• Management of plant diseases and arthropod pests byBCAs and their integration in agricultural systems, S.Michele all’Adige, Trentino, Italy, Jun. 2004

• Fundamental and practical approaches to increasebiocontrol efficacy, Spa, Belgium, Sept. 2006• Molecular Tools for Understanding and ImprovingBiocontrol, Interlaken, Switzerland, Sept. 2008

Yigal Elad – Convenor 1998-2008

• University of Udine, Italy (1990-98) Phytoplasmadiseases, viruses of cereals

• IASMA (1998-2003) Grapevine downy mildewepidemiology and biocontrol

• SafeCrop Centre (2003-2007) Biocontrol on strawberry,grapevine and cucurbits, mechanism of action

• FEM (from 2008) Resistance induced by Trichodermason grapevine, plant-pathogen-insect-BCAs interaction,development of T. atroviride SC1, gene expression inAmpelomyces quisqualis

Ilaria Pertot - Convenor from Sept. 2008

• Improving efficacy and use of BCAs(formulation, application, etc.)

• Understanding mechanisms of action (generegulation included)

• Developing tools for risk assessment andmonitoring (registration)

• Understanding the effect of climate change andthe role of biocontrol in adaptation and stresstolerance

Future main challenges for biocontrol:

• Presentations and discussions on results andachievements

• Space for new ideas, approaches, innovation,speculation

• Focus on the most relevant problems in the useof BCAs to solve them

• Education of growers and consumers

• Low cost meetings, promote participation ofyoung people

Tasks for the WG in the future:

XI Meeting of the Working GroupBiological control of fungal and bacterial plant pathogens

Climate change: challenge or threat to biocontrol?

June 7-11, 2010Graz, Austria

Local organizer:Gabriele Berg

The theme of the workshop will be:“The effect of climate change on biocontrol of

plant disease”

• The emphasis will be on the influence of climateon biocontrol, but all aspects of biocontrol mayalso be addressed

• Priority to oral presentation will be given toresearch discussing climatic aspects

• All contributions on biocontrol of diseases arewelcome!

Workshop Themes• Climate change, biocontrol and integrated plant

disease management: impact, adaptation, negativeand positive side effects on biocontrol

• Effect of climatic factors on disease development andbiocontrol

• Molecular tools to study microbial populations indifferent environments, crops and climate

• Climatic stress and biocontrol• Case studies of adaptation to climate change in

biocontrol: successes and problems encountered• Biocontrol and integrated disease management in

different environments• Integration of microbials and other adaptation tools

Workshop Themes• Commercial use of microbials for management of

diseases: present situation and prospects in a view ofclimate change, including new/near registration products

• Application of natural substances/microbials againstdiseases in different environments and climate

• Effect of climate-induced stress on host plant resistance(including resistance induced by microorganisms)

• Biocontrol and climate – all aspects• New bio resources for biocontrol• Mechanisms and signaling in biocontrol• Way to commercialization: mass production,

formulation methods and risk assessment• All aspects of biocontrol
