Copper chelate in the form of dispersible microgranules designed to prevent or correct copper deficiencies in woody or herbaceous crops. Copper acts as a catalyst in numerous physiological processes in the plant:
Copper is a low mobility element, being fixed to the soil. This fixation increases in soils rich in organic matter, clayey soils or soils with a high phosphate content. Furthermore, soils with an excess of lime or a rise in pH reduce its assimilation by the plant.
As the copper is chelated by the supplementing agent EDTA, we ensure that the copper is in a form that can be assimilated by the plant. Deficiencies in this element are first visible in the young tissues, due to their low mobility.
The symptoms are: whitish or pale yellow discolouration of the leaf tips, lack of turgidity and even necrosis. Older leaves have dry tips. All this results in a decrease in yield quality.
Stability range of copper chelate is at pH: 4 – 9.

QUELAFERT® COBRE is chelated copper (copper EDTA) in dispersible micro-granules, formulated as a copper chelate fertilizer to prevent or correct copper deficiency in woody and herbaceous crops.
It corrects copper deficiency in the crop. Because it is chelated, the copper does not get fixed in the soil, so the plant can take it up even with excess lime, high pH or high organic matter.
Copper moves little within the plant, so symptoms show first on young tissue: whitish or pale yellow leaf tips, loss of turgor and, in advanced cases, necrosis. On older leaves the tips dry out.
No. QUELAFERT® COBRE is a nutritional product. For fungal control we offer dedicated bioprotection products, such as our copper sulphate.
