Micronutrient fertilizer LURS® colofermin boron

LURS® colofermin boron is a concentrated boron micronutrient fertilizer in organic (easily digestible by plants) form for foliar feeding of potatoes, vegetables, grapes, berry crops and orchards (application rate – 20-30 mL pro 10 L water).
  • environmentally friendly microfertilizer, which eliminates effectively boron deficiency in plants;
  • stimulates pollen germination, improves pollination of flowers and fruit set;
  • enhances development of the reproductive organs;
  • provokes an intensive water absorption by plant from the soil;
  • increases drought resistance of plants by 20%;
  • decreases fruit drop, increases fruit formation;
  • provokes sugar accumulation in the tissues of winter crops and fruits of sugar beet, fruit, increases starch content in potatoes.
In which cases it is necessary to apply boron?

  • low fruit set rate, premature fruit drop or absence of premature fruit;
  • decrease in root development;
  • cessation of root and stem growth, hold-up or dieback of apical points of plants.
Which crops require boron the most?

  • potatoes
  • vegetables (cucumbers, tomatoes, carrots)
  • legumes
  • spiked cereals
  • sugar and table beet
  • sunflower
  • rapeseed
  • flax
  • alfalfa

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

Sod-podzol, gray and brown forest soils are poor in boron.

Reduction of boron digestion also occurs in acidic soils, for example calcareous soils.

Boron deficiency increases with the application of nitrogen fertilizers in excessive amounts as well as in the case of moisture deficit.

What to do if there is a lack of boron?

Application of the LURS® colofermin boron helps to eliminate the symptoms of boron deficiency and prevent their appearance.

Compatibility: LURS® colofermin boron 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.


The microfertilizer is in the liquid state and is ready for immediate use. While observing the storage conditions it does not crystallize and can be applied in a wide range of temperatures, starting from +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.
