Micronutrient fertilizer LURS® colofermin zinc

LURS® colofermin zinc is a concentrated micronutrient fertilizer for foliar feeding of field, vegetable and perennial crops.

*Colofermine is a multicomponent complexing agent (analogue of chelating agents), which consists of various organic compounds, optimally balanced for maximum absorption and plant uptake (up to 100%) of the corresponding nutrients (main active ingredient) in micronutrient fertilizers.

Depending on the type of micronutrient fertilizers, among other components, colofermin may contain colamine, various complexes of amino acids, micronutrients, including nitrogen, sulfur, sodium in sufficiently high concentrations (up to 280 g/L). Therefore, colofermin also serves as an additional source of plant nutrition.

Due to the above-mentioned factors, our formulations are more effective than the ones, produced by our competitors, even if they have a little higher concentration of an active ingredient.

LURS® colofermin zinc eliminates effectively zinc deficiency in plants. It does not contain any ballast additives, so it does not cause leaf burn. It is completely absorbed through the leaf surface of plants.

Zinc influences the process of auxin synthesis, which controls plant growth.

When nutrition with zinc is enough, and sharp change in air temperature takes place, plant respiration is less susceptible to extremes. This is one of the reasons for heat resistance and hardiness.

The presence of zinc is a prerequisite for carbohydrate synthesis in cells. With the shortage of zinc, the starch content in seeds decreases.

Crops that are in special need of zinc are as follows: corn, flax, grapes, orchards, legumes, sugar beet, sunflower, onions, potatoes, cabbage and cucumbers.

Symptoms of zinc deficiency develop throughout the plant or they are localized in the old lower leaves. First just lower and middle leaves, and then all the plant leaves are covered with gray-brown and magenta spots. Tissues of these areas die. Young leaves are abnormally small and covered with yellow spots, take slightly upright position. The root system is poorly developed. The stems are thin.

When applying LURS® colofermin zinc there is a reduction in fungal diseases affection, sugar content of fruit and berry crops increases. Drought, cold and heat resistance of plants increase.

The formulation contains a high concentration of zinc ions, which provides a reduction in rate of application and hence expenses per hectare. The formulation is very rapidly absorbed by leaves and eliminates diseases caused by zinc deficiency.

Composition of zinc and sulfur, which is a part of the formulation, intensifies growth of the vegetative mass and inhibits fungal diseases. Nitrogen in LURS® colofermin zinc is in the form of amide and ammonia, which enhance root development.

LURS® colofermin zinc can be used in any water. There is no danger of the calcium sulphate (gypsum) formation.

Compatibility: LURS® colofermin zinc 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.

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.

Treatment during the flowering period is not recommended.

colofermin zinc has a significant physiological effect on plants, namely:
  • increases drought, cold and heat resistance;
  • enhances plant persistence to fungal diseases;
  • enhances root development and regulates the growth of the vegetative mass;
  • stabilizes chlorophyll, carbohydrate and protein synthesis in the cells;
  • accelerates the rate of chlorophyll formation, prevents the destruction of chloroplasts;
  • increases sugar content of fruit and berry crops.
It is recommended for use in conjunction with VIMPEL ®plant growth stimulator.
