Detection of the disease

The purpose of the detection would be to determine if the tree is infected by X.F. For this, there is a method called PCR (Polymerase Chain Reaction) that can detect the presence of viruses or measure viral loads. However, this is a complex method that requires DNA sampling on the tree, which will undergo various treatments in the laboratory, so it is not a way to detect X.F. on the field.

Therefore, this project focuses on detecting the drying of the tree which is one of the first symptoms of X.F. In the case of the olive tree, this method is relevant because the olive tree is an evergreen tree, its leaves will not dry naturally if the tree is healthy. However, the drying of the tree can be caused by other factors than XF, the solution presented here serves primarily as a warning device, it is appropriate after detecting the drying of a tree to take a sample and to ensure that it is XF which infects the tree before injecting the remedy developed by the team.
