Copper complex with heptagluconic acid

5 % Water-soluble copper (Cu) 60 g/l

Density: 1,23

pH-Value: 8,5

Color: green-black


Our products are tested between -10 °C and + 45°C and can be stored within this temperature-range. Occurring crystals due to cold storage will dissolve again at higher temperatures. We recommend a frost-free storage and a product-temperature above +5 °C at the time of use.


Lebosol®-HeptaKupfer is compatible with the common plant protection products. Since not all the influences appearing in practice are predictable, a miscibility test with small amounts of the products provided for the spraying is always useful. In case of mixture with fertilizers or plant protection products fill sprayer up to 2/3 with water and add products separately. Add Lebosol®-HeptaKupfer as the last component. Apply immediately stiring constantly.

Product active agent

Copper availability is low on humic, sandy, friable soil, on soil with a high pH-value, during cold or in waterlogged or very dry soils.

Copper deficieny is shown by twisted flag leaf and twisted younger leaves, shrivelling leaf tips, blind grain sites on ears, poor grain formation, stunted plants. Especially in oats, wheat and barley; rye and triticale are less sensitive.
