Abstract
A better understanding of the disease cycle of fire blight in the beginning of the season and of the formation of primary inoculum on pear trees is a very important factor for a good applicability of a warning system.
In our experimental plots on pear trees, we observed heavy ooze formation on apical parts, fruitlets and shoots, before any canker activity could be found in the orchard.
Apical transport of E. amylovora bacteria within the vascular system of the tree over longer distance is supposed to be possible.
