Micronutrient fertilizer LURS^® colofermin calcium

LURS^® colofermin calcium is a concentrated micronutrient fertilizer for elimination of plant physiological disorders due to calcium deficiency.

*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.

When calcium deficiency takes place, under fruit skin its flesh becomes brown in some places. Then spots (subcortical spotting) appear in these places on the skin. They cork over time (cork spot). The fruits lose their marketable qualities.

LURS^® colofermin calcium contains water softener, therefore the use of plant protection products in the hard water (high content of Ca²⁺ and Mg²⁺) in conjunction with LURS^® colofermin calcium does not reduce their effectiveness. Hardness salts are reliably bound by the formulation component, without causing turbidity of the spraying solution. There is no danger of the calcium sulphate (gypsum) formation, which can lead to breakdown of spraying machinery. When conducting treatments use а freshly mixed solution.

LURS^® colofermin calcium has a significant physiological effect on plants, namely:

• regulates the construction of the cell membranes;
• provides resistance to pests;
• increases the viscosity and permeability of protoplasm;
• stimulates processes of nitrogen fixation and transition of carbohydrates;
• improves fruit marketable qualities.

Due to its composition the microfertilizer can be applied in a wide range of temperatures, starting from +5° C.

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.

3. PREPARATION OF WORKING TANK SOLUTION:

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: 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.

Tank mix

Attention! In preparing a tank mix, care should be taken to ensure that the mixing of the components (such as growth regulators, PPPs, microfertilizers, etc.) is conducted solely in water!

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: 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.

Formulation viscosity does not decrease at -35 ºС (-31 ºF).

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

7. WHO CLASSIFICATION, TOXICITY: 4^th toxicity class. The formulation is nontoxic, does not cause allergies, is environmentally friendly and absolutely harmless to pollinating insects.

8. PRECAUTIONS: keep away from children and animals. When carrying out spraying operations, use the appropriate and adjusted equipment, follow generally accepted safety standards.

9. FIRST AID INSTRUCTIONS: if the skin or eyes are contaminated with the preparation, flush them with water. If necessary, call a doctor.

10. CONTAINER AND LEFTOVER FORMULATION DISPOSAL: a container and leftover formulation do not require specific methods of disposal and neutralization.

11. STORAGE PERIOD: 5 years.
