In a fungicidal and bactericidal composition comprising an organic copper salt, the compounds are either of general formula Cu 2+ -2R − with a ratio 1:2 between the copper portion and the organic radical, whereby this radical has either the form O t− —CO—CH(SH)—CH 3 or the form O t− —CO(CH 2 ) 2 —CO—CH 3 or the compounds are of general formula Cu 2+ —R 2− with a ratio 1:1 between the copper and the organic radical; in this case, the radical has the form (a). The copper-organic composition exists as chelate or as Co a complex, whereby the copper ions are spatially shielded so that, in a slow release process, they are transferred to plants to be treated. |
