Third Announcement

On behalf of the IOBC/WPRS Working group “Integrated Plant Protection in Fruit Crops” Sub Group “Pome Fruit Diseases”, you are cordially invited to the forthcoming 12th International IOBC/WPRS Workshop on Pome Fruit Diseases that will take place from 13 to 16 June 2022 in Plovdiv, Bulgaria. The workshop was originally scheduled for June 2020; however, due to the pandemic the workshop has been postponed by two years. Another severe occurrence in Europe is the war in Ukraine. However, at the moment (late March 2022) we do not foresee any challenges due to Covid or the war in Ukraine in respect of having the meeting in mid-June. We aim to bring together the latest advances in research of pome fruit diseases, to provide an opportunity for exchange of information and ideas and to stimulate common research and collaboration. The workshop program includes oral and poster sessions, plenary discussions, a meeting with growers and advisors and a one-day excursion. Proposed topics: Diagnostic tools, pathogen biology and epidemiology, monitoring and forecasting infection risks, host-plant resistance and biodiversity, control methods (biocontrol, chemical, alternative, physical, sanitation), spray quality and disease control, canker diseases, postharvest diseases, soil borne diseases, and replant disease. Special attention will be given to poster presentations in plenary discussions during the meeting. There will be a special symposium on sustainable disease management where growers and advisors from Bulgaria and neighboring countries will be invited to attend. The official website is https://iobc-plovdiv2022.eu/ 

Language

The official language is English.
