Phytosanitary agent and its particular use in the treatment of plants infected by Xylella fastidiosa

Abstract

The invention relates to the use of an organometallic coordination complex or its phytopharmaceutically acceptable salt of a Mm+ metal and of at least one L ligand, where Mm+ is a transition metal having an oxidation number m, L is a ligand of general formula (VII) or its anion, wherein R1 is selected from the group consisting of oxygen, mono or polycyclic alkyl, naphthalene residue, anthracene residue and their hydroxylated or ketone derivatives; R2 and R3 are identical or different and are selected independently of each other from hydrogen, halogen, a hydroxyl group, an alkoxy group, a linear or branched alkyl group, a cycloalkyl group or R2 and R3 together forming a benzene derivative; R6, R7 and R8 are identical or different and independently of each other are selected from hydrogen, a hydroxyl group, an alkoxy group, a linear or branched alkyl group, a cycloalkyl group, a phenyl group, an aryl group in the treatment of Xylella fastidiosa in a plant. The invention also concerns the use of the compound of formula (VII) in the treatment of Xylella fastidiosa in a plant, also in combination with the organometallic coordination complex. Advantageously, the invention concerns the treatment of olive trees.
