The reason for this unusual form is that that the editor did not manage to finish his editing duties in time before the last meeting took place. I am aware of the shortcomings, which are related to a delay of publishing the manuscripts; this is especially unsatisfactorily for students. I apologize for any inconvenience related to this delay. The first part of the Bulletin contains 38 papers presented at the penultimate meeting of the Working Group at the Gödöllö University of Agricultural Sciences, Hungary, from 31st October to 3rd November 1999, organised by Prof. Dr. G. Bujaki, T. Bukovinsky and H. Tréfás. The second part of the Bulletin contains 20 papers of the last meeting of this Working Group at the Agricultural University of Krakow, from 13th October to 18th October 2001, organised by Prof. Dr. K. Wiech and M. Pniak. We all enjoyed the outstanding hospitality and the perfect organisation of both the scientific and social part of the meetings. More than 50 colleagues attended both meetings, coming from Eastern and Western parts of Europe; we also acknowledged the participation of colleagues from the USA and Canada. At both meetings we had presentations at a very high standard and the intensive discussions underlined that both basic research and extension of protection measures are integral parts of the group. Attempts to integrate colleagues working on issues related to the protection of field vegetables from plant diseases were only in part successfully. Since several years the production of “Guidelines” for field vegetable crop production has been discussed within the group quite controversially; however, Dr. Joerg presented some preliminary ideas on this topic during the Krakow meeting and we are now looking forward to discuss a first version of these “Guidelines” during the next meeting, which will be held at Ghent, Belgium in 2003.
