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

摘要

Biocidal composition, in particular fungicidal and / or bactericidal, comprising a thiosemicarbazone of 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 comprising inorganic and / or organic binders as well as the salts of said compounds, formula in which Y represents CH or N, X1 represents hydrogen, halogen, phenoxy, alkoxy comprising from 1 to 6 C atoms or an alkyl comprising from 1 with 6 straight or branched chain C atoms, n is 1, 2 or 3, or (X1) n taken together form a molten benzene ring, R1 represents hydrogen or an alkyl having 1 to 6 straight chain C atoms or branched; R2 and R3 each independently represent hydrogen, straight chain or branched alkyl or alkenyl having up to 18 carbon atoms, cycloalkyl, arylalkl, heteroarylalkyl, aryl, substituted aryl, heterocycle containing one or more hetero atoms, an acyl, an acyl, a hydroxy or an alkoxy, an alkylsulphonyl or an arylsulphonyl, an amino, an alkylamino or dialkylamino, an arylamino, a hydroxyalkyl or an alkoxyalkyl, an aminoalkyl, a monoalkylaminoalkyl or an alkylcarylalkylaminoalkino or an alkylcarylalkylaminoalkino; R2 and R3, taken with the hydrogen atom to which they are attached, form a heterocycle which may optionally contain one or more additional heterosupplementary atoms selected from O, N and S. The compounds of the present invention and their metal complexes can be used in particularly for combating or preventing attacks by fungi or bacteria on plants or plant material, including seeds.
