Abstract: The present invention relates to the use of a phytotherapeutic composition comprising:—a carbonate substituted hydroxyapatite having the formula (I): Ca(10-y/2)(PO4)(6-y)(CO3)y(OH)2 (I) wherein y is comprised between 0.01 and 2: and—at least one bioactive compound selected from the group consisting of: anaromatic plant extract and/or an active substance thereof, a metal ion, and acarboxylic acid; as phytotherapeutic agent for the endotherapeutic treatment of a plant.

Abstract: The invention relates to a to novel photostable compositions of carbonate-substituted hydroxyapatite containing at least one vegetable extract of at least one plant of the Chrysanthemum or Tanacetum genus.

Abstract: The subject matter of the invention is a carrier loaded with bioactive substances, wherein the carrier is carbonate substituted hydroxyapatite and the bioactive substances are an ion and a plant extract, wherein the ion is selected from the group consisting of Cu, Zn and a combination thereof, and wherein the plant extract consists of mint extract, rosemary extract, Ocimum basilicum extract, lemon extract, garlic extract, clove extract, thyme extract and cinnamon extract.

Abstract: The subject matter of the invention is a carrier loaded with bioactive substances, wherein the carrier is carbonate substituted hydroxyapatite and the bioactive substances are an ion and a plant extract, wherein said ion is selected from the group consisting of Cu, Zn and a combination thereof, and wherein the plant extract consists of mint extract, rosemary extract, Ocimum basilicum extract, lemon extract, garlic extract, clove; extract, thyme extract and cinnamon extract.

Abstract: The subject matter of the invention is a hydroxyapatite carrier, corresponding to the formula: Ca(10-x)Mx(PO4)(6-y)(CO3)y(OH)2 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 Pseudomonas syringae), olive quick decline syndrome (caused by Xylella fastidiosa) and Citrus bacterial canker disease (caused by Xanthomonas axonopodis).

Abstract: The subject matter of the invention is a substituted hydroxyapatite carrier, responding to the formula: Ca(10-x)Mx(PO4)(6-y)(CO3)y(OH)2 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, with the proviso that x and y are never equal to 0 at the same time. The substituted hydroxyapatite is a carrier of a bioactive substance chosen among a metal ion selected from Mn, Mg, K, Fe, B, Mo, Se and/or an extract of vegetal origin. The invention relates also to the use of the carrier for the delivery of such a bioactive substance to plants in order to achieve the phytosanitary and/or nutritional treatment of the plant.
