Zinc complex with heptagluconic acid

6 % Water-soluble zinc (Zn) 80 g/l

Density: 1,3

pH-Value: 6,0

Color: brown


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®-HeptaZink 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®-HeptaZink as the last component. Apply immediately stiring constantly.

Product active agent

Zinc availability is low on humic soils, with high pH-value, in phosphorus rich soils and in cold wet conditions.

Zinc deficiency is shown by pale stripes, orange tinge, stunted plants and small leaves.
