FERTUM ® Copper is a nutrient corrector, in liquid form and used by spraying on leaves, based on complexed copper soluble in water and chelated with extracts of native seaweed from the south of Chile. Formulated to avoid and correct copper deficiencies; a micronutrient with an important biological role during plant photosynthesis and respiration.

FERTUM ® Copper stimulates the production of phytoalexins so its use has fungistatic effects. We suggest applying the recommended doses: when new sprouts and shoots start appearing at the beginning of the rainy season; after pruning and cutting; and at the beginning of flowering.

FERTUM ® Copper allows the quick absorption of mineral nutrients because they are combined with natural low molecular weight chelating agents. It is recommended for use on crops established on copper deficient soils.


  • Guarantees better fruit quality.
  • It improves taste, storage life and resistance to transport of fruit and vegetables, as well as sugar content.

We recommend applying FERTUM ® Copper repeatedly during the crop's vegetative stage. Apply on soils with copper and sulphur deficiencies, or with high concentrations of phosphorus, where it is difficult to assimilate copper. And on soils that show induced copper deficiencies, caused by oversupply of nitrogen fertiliser, and as a supplement when applying soil fertilisers.

Applying FERTUM ® Copper we can correct specific deficiencies like:

  • Cereals: When yellow spots appear on leaves, or they wither or die before developing.
  • Citric plants: Very dark green long leaves; branches die gradually and get covered in gummy secretions; fruit falls before maturity, has a tough skin and little juice.
  • Vegetables: Delayed growth; chlorotic loss of colour and very thin leaves.
  • Rice: Yellow tips or withered tips followed by death of leaf tissue before developing.
  • Flowers: Whitish area at the leaf's apex, which deforms.
  • Common bean: Brown or reddish spots on the fruit surface, growth reduction in young buds. Plant shows chlorotic appearance and withering.
  • Grasses: Growth reduction of sprouts; chlorotic appearance and withering of the plants.
  • Potato: Asymmetric chlorosis on one side of the leaves due to excess copper.
