Micronutrient fertilizer LURS® colofermin copper

LURS® colofermin copper is a concentrated micronutrient fertilizer for foliar feeding of potatoes, vegetables (application rate – 20-30 mL pro 10 L water), grapes, berry crops and orchards (application rate – 40-50 mL pro 10 L water).
  • is a micronutrient fertilizer of high purity, which eliminates effectively copper deficiency in plants;
  • enhances plant resistance to diseases and decreases disease development;
  • improves root development;
  • provokes an intensive water absorption by plant from the soil, thus increasing drought resistance;
  • provokes sugar accumulation in root crops and vitamin C content in fruits.
In which cases it is necessary to add copper?

  • the edges of old leaves die off, they curl, chlorosis occurs;
  • new leaves become large in size and acquire pale color;
  • poor fruit set of spiked cereals.
Which crops require copper the most?

  • potatoes
  • vegetables (cabbages, tomatoes, carrots, onions)
  • beans, soybeans
  • spiked cereals
  • sugar beet
  • corn
  • flax
  • alfalfa

Soils with copper deficiency and other factors affecting the absorption of copper

The lack of copper is observed on turfy and acidic sandy soils.

What to do if there is a lack of copper?

Application of the LURS® colofermin copper will aid in the elimination of copper deficiency in plants.

Compatibility: LURS® colofermin copper performs well in tank mixes with herbicides, insecticides, fungicides and biological preparations. Prior to starting preparation of a tank mix, always check the formulations for compatibility.


Does not crystallize. Storage at low temperatures may result in the product gelling. Increase of ambient temperature causes the increment of the liquid viscosity. The composition of the microfertilizer allows conducting treatments at an air temperature
above + 5°С.

To avoid leaf and fruit burn, do not apply the formulations in high air temperatures. To obtain the maximum effect, it is advisable to conduct treatments in the evening (at a temperature below + 25°С).

Treatment during the flowering period is not recommended.

It is recommended for use in conjunction with VIMPEL ®plant growth stimulator.
