QUELAFERT® COBRE

Copper chelates (EDTA)

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:

  1. It is part of many proteins.
  2. It is present at various stages of the photosynthesis process.
  3. Promotes nitrogen utilisation and protein synthesis.

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.

PRODUCT TYPE

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.

BENEFITS OF THIS CHELATED COPPER FOR PLANTS

  • Delivers available copper even in calcareous, clay or high-organic-matter soils, where copper is usually locked up.
  • Supports nitrogen use and protein synthesis.
  • Takes part in several stages of photosynthesis, which translates into higher-quality yields.

QUELAFERT® COBRE FEATURES

  • EDTA chelating agent, stable between pH 4 and 9.
  • Dispersible micro-granules in 1 and 5 kg packs.
  • Rates per tree for orchards and per hectare for vegetables (see table).

Chelated copper FAQ

What is chelated copper used for?

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.

How do I recognize copper deficiency?

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.

Is it the same as a copper fungicide?

No. QUELAFERT® COBRE is a nutritional product. For fungal control we offer dedicated bioprotection products, such as our copper sulphate.
