Micronutrient fertilizer ORAKUL® colofermine of magnesium

ORAKUL® colofermine of magnesium is a concentrated micronutrient fertilizer for foliar feeding of field, vegetable and perennial crops.
ORAKUL® colofermine of magnesium eliminates effectively magnesium 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.

Magnesium is part of chlorophyll, it is in nucleins, phytin and pectin substances. It supports the structure of ribosomes by binding RNA and protein. Magnesium has a positive effect on the absorption of phosphorus.

The following crops are sensitive to the lack of magnesium: corn, sorghum, sugar beet as well as potatoes, legumes and grapes.

Magnesium deficiency can be observed on plants in the areas of high humidity in the sod-podzolic soils of light mechanical composition, as part of magnesium available to them is washed into deeper horizons. Cold spring and low pH level (<5.0) reduce the availability of magnesium present in the soil for plants.

Magnesium deficiency results in the destruction of chlorophyll. The affect is more visible on older leaves. Leaf veins remain green, and the areas of tissues located between the veins have a pale color. This is called a spotted (marble) chlorosis. The edges of leaves curl and die.

At the first signs of chlorosis or as prophylaxis for soils poor in magnesium it is necessary to carry out foliar feeding. Application of ORAKUL® colofermine of magnesium at the beginning of the disease restores the color of leaves and regeneration processes of chlorophyll. With reinforced outflow of sugars from leaves to fruits and seeds, ORAKUL® colofermine of magnesium improves the quality of products. The formulation contains a high concentration of magnesium ions providing decrease of application doses, and hence the cost per hectare.

Nitrogen in ORAKUL® colofermine of magnesium is in a reduced form, which is easily absorbed by the surface of the leaves and improves root development.
ORAKUL® colofermine of magnesium can be used in any water. In hard water, the active substance does not interact with hardness salts (calcium and magnesium), so there is no danger of the calcium sulphate (gypsum) formation, which can lead to breakdown of spraying machinery.

 ORAKUL® colofermine of magnesium has a significant physiological effect on plants, namely:
  • restores the regenerative processes of chlorophyll and enhances protein synthesis system;
  • prevents the destruction of chloroplasts, which makes photosynthesis the most efficient;
  • speeds up the progress of growth processes and cell division;
  • increases activity of enzymes;
  • provokes an intensive water absorption by plant from the soil, increasing drought resistance;
  • increases the product quality.
It is recommended for use in conjunction with VIMPEL® plant growth stimulator .

1. INFORMATION FOR CONSUMERS: follow the instructions when using the formulation. The efficacy of the formulation and its ease of use depend on the application, storage and transportation conditions specified by the manufacturer.

2. COMPATIBILITY WITH OTHER FORMULATIONS: the micronutrient fertilizer is applied during the growing season either prophylactically or according to the diagnostics results based on the application regulations. It performs well in tank mixes with plant protection products (unless otherwise specified by the manufacturer of the plant protection products), urea (in the recommended concentrations when using foliar fertilization of agricultural crops according to the crop growth stages), UAN, plant growth regulators, microfertilizers and biological preparations.


Warning! Prior to starting preparation of a tank mix, always check the formulations for compatibility!

For this purpose take a container, pour in it some water (which is to be used for the main application), add the tank mix components in proportions, based on the field rates of consumption. After closing the container, mix the contents by shaking it 10-15 times. Evaluate the tank mixture visually twice: immediately after mixing and after the mixture has settled (in about 30 minutes). Incompatibility of formulations is indicated by their separation into layers, residuum occurrence, flocculation of the mixture, formation of sludge that does not disperse.

Attention! It is possible to use the formulation in hard water. The active substances contained in it do not form compounds with hardness salts (СаSO4٠2H2О), hence the solution does not grow turbid.

If there are no compatibility problems, prepare the working solution just before spraying (direct application). Shake the product thoroughly in the original package and pour it directly into the sprayer tank, which is to be previously filled with water to 2/3 of its volume. After this with the mixing mode turned on add the components of the tank mixture in sequence stated in the recommendations and finish the process with filling the tank with water. Stirring of the mixture should be continued throughout the period of its preparation, as well as during application.

Application rates of the spraying solution: field crops — 70-300 L/ha, vegetables — 300-400 L/ha, fruit crops and grapes — 800-1000 L/ha.

4. MIXING ORDER OF SPRAYING SOLUTION COMPONENTS: when preparing the tank mixture, stick to the following sequence of components.

5. APPLICATION REQUIREMENTS: spraying should be done either early in the morning or in the evening, when the humidity level is high to avoid chemical leaf burn. The optimum air temperature is +10...+25 °С (50 — 77 ºF), wind speed up to 5 — 7 m/s depending on the sprayer type. It is not recommended carrying out spraying operations during foggy weather or in the presence of dew, which can lead to surface overflow of the solution and hence the reduction of the treatment efficiency. The spraying should be stopped 1.5 — 2 hours before the rain.

Attention! Use а freshly mixed solution. Do not store the prepared solution more than 24 hours.

6. STORAGE AND TRANSPORTATION: storage and transportation must be carried out in accordance with ГОСТ 14189 (National State Standard).

The formulation should be stored in a warehouse or storage building, designed specifically for this purpose. Storage area should be free of direct sunlight, moisture, pollution and mechanical damage to the container. Store at temperature above 0 ºС below +30 ºС (50 — 86 ºF), in the original closed package in an upright position, with the cap facing up in a cardboard box. Do not stack cardboard boxes more than 3 high.

Decrease of temperature below -30 ºС (-22 ºF) results in the product decrease of viscosity, the prolonged storage may cause sediment formation.

Any form of transport is possible while in covered vehicles. The use of open vehicles, which provide protection against precipitation, is allowed as well.
