LURS® colofermin iron
is a concentrated micronutrient fertilizer for foliar feeding of potatoes and vegetables (application rate – 20-30 mL pro 10 L water), as well as grapes, orchards, berries, ornamental crops, flowers and turf grass (application rate – 40-50 mL pro 10 L water).
-
is a micronutrient fertilizer of high purity, which eliminates effectively iron deficiency in plants;
-
does not cause leaf burn, is completely absorbed through the leaf surface of plants;
-
when applied as a preventive measure prevents chlorosis development;
-
improves the water-holding capacity of plant tissues, increases viscosity of protoplasm and osmotic pressure;
- enhances root development.
In which cases it is necessary to add iron?
-
at the first signs of chlorosis in the leaves chlorophyll formation is suppressed, leaves lose their green color, darken and fall prematurely;
- plant growth slows down.
Which crops require iron the most?
- berry crops (strawberries, raspberries)
- orchards (apple, pear, cherry trees)
- potatoes
- vegetables (cabbage, tomatoes)

Soils with iron deficiency and other factors affecting the absorption of iron
Iron deficiency is most often observed on calcareous soils. Phosphate fertilizers also affect the solubility of iron: addition of high doses of it promotes the formation of low-soluble iron phosphate in the soil.
What to do if there is a lack of iron?
Application of the LURS® colofermin iron no later than 5 days after the onset of the disease restores the color of the leaves.
Compatibility: LURS® colofermin iron 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.
Attention:
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.
The formulation contains a high concentration of ions of iron, which provides a reduction in dose of its application, and subsequently the costs per hectare.
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: 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.
Tank mix
- Water
- Plant growth regulators
- Plant protection products
- LURS® colofermin iron
- Other micronutrient fertilizers (excluding LURS® sulphur active)
- Water
Tank mix with UAN
- Water
- Plant growth regulators
- UAN according to the foliar application recommendations 3-12%+2,5% MgSO4٠7H2O (5% Decahydrate)
- Plant protection products
- LURS® colofermin iron
- Other micronutrient fertilizers
- Water
Tank mix with urea
- Water
- Plant growth regulators
- Urea according to the foliar application recommendations using other liquor (either into the sprayer tank or on the filter)
- Plant protection products
- LURS® colofermin iron
- Other micronutrient fertilizers
- Water
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.
Decrease of temperature below -15 ºС (5 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.
7. WHO CLASSIFICATION, TOXICITY: 4th 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.
