Multiplex Iron Micronutrient Fertilizer – Ferrous Sulphate 19% Powder for Iron Deficiency & Chlorosis Control

Multiplex Iron is a micronutrient fertilizer from Multiplex that supplies iron to crops in a water-soluble powder form. It contains Ferrous Sulphate (19%) as its active ingredient, which is a reliable and widely used source of iron for correcting iron deficiency in plants. Iron is an essential micronutrient that plays a central role in photosynthesis and is also involved in the breakdown of carbohydrates inside plant cells. When crops get enough iron, they grow normally and produce high-quality yields.

Iron deficiency, commonly seen as yellowing of young leaves with green veins (interveinal chlorosis), is a frequent problem in many Indian soils, especially alkaline and calcareous soils where iron gets locked up and becomes unavailable to plants. Multiplex Iron helps correct this deficiency quickly and supports healthy green growth. It can be used on a wide range of crops including Maize, Cabbage, Sugarcane, Groundnut, Peach, Apple, Citrus, Berry, Grape vines, Sorghum, Soybean, Strawberries and Raspberry. The product can be applied either as a foliar spray for quick correction or through soil application for long-term maintenance.

Key Benefits

• Corrects iron deficiency (chlorosis) and restores the deep green colour of leaves
• Supports chlorophyll formation, which improves the plant's ability to photosynthesise and convert sunlight into energy
• Helps in carbohydrate breakdown inside plant cells, releasing energy needed for healthy growth
• Promotes normal, vigorous plant growth and supports high-quality yields
• Provides dual nutrition with iron for energy and sulphur for protein synthesis in one application
• Can be used as a foliar spray for quick results or as a soil application for long-term correction
• Suitable for a wide range of field, horticultural and plantation crops
• 100% water-soluble powder that mixes easily and is simple to apply

How It Works

Iron is a vital micronutrient that acts as the metabolic engine of the plant. Without it, the plant's energy systems slow down and leaves start turning yellow. Multiplex Iron works by supplying iron directly to the plant through its Ferrous Sulphate content, which is readily absorbed and used by the crop.

Inside the plant, iron is required for chlorophyll synthesis, which is the green pigment that captures sunlight for photosynthesis. When iron is supplied, the plant can restart chlorophyll production, turning pale yellow leaves back to green and allowing the plant to use sunlight efficiently. Iron also acts as a carrier in the plant's energy chain, helping move energy from the leaves to the fruit or grain. In addition, it activates key enzymes that help convert nitrate fertilizers into proteins, supporting overall growth and development. The result is a darker green canopy, active growth, and better yields.

Technical Specifications

Recommended Dosage & Application

For foliar spray, dissolve 2.5 g of Multiplex Iron in 1 litre of clean water and spray liberally on both surfaces of the leaves. For soil application, apply 10 kg per acre for all crops and distribute evenly across the soil for optimal absorption.

When to Use

Apply Multiplex Iron during active vegetative growth or whenever iron deficiency symptoms are noticed for quick recovery. The classic sign of iron deficiency is yellowing of young leaves while the veins remain dark green (interveinal chlorosis). Growth becomes stunted if the deficiency is not corrected.

For best results, follow this schedule: first spray at the vegetative stage (15–20 days after planting or germination) and a second spray before flowering. Apply during the morning or evening and avoid spraying in hot midday sun to prevent leaf burn. In high pH (alkaline) soils, foliar spray is highly recommended because soil-applied iron can get locked up and become unavailable to the plant.

Step by Step Usage Instructions

Foliar Spray:

1. Take clean water in a spray tank.
2. Dissolve 2.5 g of Multiplex Iron in 1 litre of water (adjust quantity based on your tank size).
3. Stir well until the powder dissolves completely.
4. Spray liberally on both the top and bottom surfaces of the leaves, as the underside absorbs nutrients faster.
5. Use the solution immediately; do not let it sit for hours as it may oxidize.

Soil Application:

1. Measure 10 kg of Multiplex Iron per acre.
2. Mix with sand or compost for even distribution.
3. Apply evenly across the soil for optimal absorption by the crops.

Safety during application: Wear protective gloves and a mask while handling the product. Avoid inhalation and direct contact with the skin and eyes.

Compatibility

Multiplex Iron is compatible with most fertilizers and micronutrients, including Urea and Potash. However, avoid mixing it with highly alkaline solutions, alkaline pesticides, or phosphorus-heavy fertilizers, as this can cause the iron to become solid and useless. Do not mix with highly alkaline products like Bordeaux mixture. Always do a jar test before mixing with any new product to confirm compatibility.

Precautions & Safety

• Wear protective gloves and a mask while handling the product
• Avoid inhalation and direct contact with the skin and eyes
• Do not contaminate water sources with the product or its packaging
• Follow local regulations for safe disposal of the product and its packaging
• Store in a cool, dry place away from children, food, and animal feed
• Keep the container tightly closed when not in use, as the powder can react with moisture and oxygen and turn into rust
• Do not exceed the recommended dose, as iron sulphate is a salt and overdosing can cause leaf burn

Side Effects & Phytotoxicity

Iron sulphate is a salt, and exceeding the recommended dose of 3 g per litre can cause leaf burn (scorching). Always stick to the recommended dosage. The powder may turn brown if left open, as ferrous sulphate reacts with moisture and oxygen. Keep the packet tightly sealed in a dry place to prevent this.
