Summary:(10-x)x4(6-y)3y2 Pseudomonas syringaeXylella fastidiosaXanthomonas axonopodisThe subject matter of the invention is a hydroxyapatite carrier, corresponding to the formula: CaM(PO)(CO)(OH)in which: M is chosen from Cu, Mg, Zn, Pb, Cd, Ba, K, Mn, Mo, Fe, Ag, B, Se or a combination of at least two of such elements; -x is comprised between 0 and 2, preferably between 0 and 1, more preferably between 0 and 0.8, even more preferably between 0.02 and 0.05; -y is comprised between 0 and 2, preferably between 0 and 1, more preferably between 0.002 and 0.030, The hydroxyapatite is a carrier of a bioactive substance chosen among a metal ion selected from Cu, Zn, S, Mn, Mg, K, Fe, B, Mo, Se and/or an extract of vegetal origin. The bioactive substances are active in the treatment of vascular diseases of plants, in particular: grapevine yellows (caused by grapevine phytoplasma), bacterial canker in kiwifruit (caused by ), olive quick decline syndrome (caused by ) and Citrus bacterial canker disease (caused by ).
