A BIOCIDAL, PARTICULARLY FUNGICIDAL AND/OR BACTERICIDAL COMPOSITION AND THIOSEMICARBAZONES AND METAL COMPLEXES THEREOF FOR USE IN THE COMPOSITION

摘要

A biocidal composition, particularly a fungicidal and/or bactericidal composition, comprising a thiosemicarbazone having the general formula (I), and their complexes formed by reaction with compounds of the metals Cu, Zn, Mn, Fe, Ca, Mg, Al, Sn and Ti and having inorganic and/or organic ligands, and salts of said compounds, in which formula Y represents CH or N, X1 represents hydrogen, straight or branched chain C1-C6 alkyl, C1-C6 alkoxy, phenoxy or halogen, and n is 1, 2 or 3, or (X1)n when taken together form a fused benzene ring, R1 represents hydrogen or straight or branched chain C1-C6 alkyl, and R2 and R3 each independently represents hydrogen, straight or branched chain alkyl or alkenyl having up to 18 carbon atoms, cycloalkyl, arylalkyl, heteroarylalkyl, aryl, substituted aryl, a heterocyclic ring containing one or more hetero atoms, acyl, hydroxy or alkoxy, alkylsulphonyl or arylsulphonyl, amino, alkylamino or dialkylamino, arylamino, hydroxyalkyl or alkoxyalkyl, aminoalkyl, monoalkylaminoalkyl or diakylaminoalkyl, alkoxycarbonylalkyl or alkylideneimino, or R2 and R3 when taken together with the nitrogen atom to which they are attached form a heterocyclic ring which may optionally contain one or more additional hereto atoms selected from O, N and S. The compounds of the invention and their metal complexes may particularly be used for combating or preventing attacks by fungi or bacteria on plants or plant material including seed material.
