The purpose of the mission was to make a phytosanitary inspection of the Mitzic estate, make recommendations for controlling leaf diseases, draw up an experimental protocol for ULV defoliant treatment and propose a system of general foliage monitoring at the estate. In addition to those recommendations, the expert proposed that a clone trial be resumed and touched upon "parasitic phanerogams" and root diseases (with a view to new plantations), but no experimental protocol was set in place for those subjects. The expert will ensure scientific monitoring of the trials set up. Two other missions have been requested by SIAT in 2007.
