Cuprum

Cuprum is a CE marked fertiliser that contains micro copper. Copper strengthens the plant’s natural immunity due to its positive effect on defence protein production. Half a litre of Cuprum (containing five grams of micro copper) is enough to spray a whole hectare. The result is significant savings compared, for example, with the application of copper oxychloride. It also means no residue, no growth inhibition, no re-entry restrictions and no safety term before harvesting. Together with Ds-Lime and ManZincum, it is used to make our Ds-mix.
