HPM Heera Zinc Plus - Zinc Sulphate Monohydrate 33% Micronutrient Fertilizer for Foliar Spray

HPM Heera Zinc Plus is a high-quality micronutrient fertilizer containing Zinc Sulphate Monohydrate 33%. Zinc is one of the most essential micronutrients required by plants for balanced growth and productivity. This water-soluble foliar spray formulation is designed to correct zinc deficiency in crops, improve nutrient availability, and support healthy plant development.

Zinc deficiency is a common problem in Indian soils, leading to stunted growth, yellowing of leaves, poor flowering, and reduced yields. HPM Heera Zinc Plus provides a concentrated and readily available source of zinc that plants can absorb quickly through foliar application. It helps improve chlorophyll content, strengthens plant immunity, and contributes to better flowering, fruit set, and overall crop productivity.

This product is suitable for a wide range of crops including cereals, pulses, vegetables, fruits, oilseeds, and plantation crops. It comes in a convenient powder form that dissolves easily in water for foliar spray application.

Key Benefits

• Corrects zinc deficiency: Quickly addresses common zinc deficiency symptoms like yellowing leaves, stunted growth, and poor tillering in crops.
• Improves crop greenery: Enhances chlorophyll production, giving crops a healthy dark green colour and improving photosynthesis.
• Strengthens disease resistance: Helps plants build natural immunity and tolerance against stress and diseases.
• Supports better flowering and fruiting: Zinc plays a key role in auxin production, which supports stem growth, root development, and flower formation.
• Improves nutrient absorption: Enhances the plant's ability to take up and utilise other nutrients from the soil.
• Boosts crop yield and quality: Contributes to higher productivity and better quality of harvests.

How It Works

Zinc is an essential micronutrient that acts as a metabolic activator in plants. It plays a critical role in the production of auxins — plant hormones responsible for stem elongation, root development, and overall plant structure. When applied as a foliar spray, HPM Heera Zinc Plus is absorbed directly through the leaf surface, providing a quick and efficient supply of zinc to the plant.

Once inside the plant, zinc activates several enzyme systems involved in photosynthesis, protein synthesis, and carbohydrate metabolism. It helps in the formation of chlorophyll, which gives leaves their green colour and is essential for converting sunlight into food energy. Zinc also supports the development of reproductive structures, improving pollen viability, grain filling, and fruit set. By correcting zinc deficiency at the leaf level, the product ensures that plants can grow vigorously, resist stress better, and produce higher yields.

Technical Specifications

Recommended Dosage & Application

Foliar Spray Dosage: 250 grams per acre dissolved in 250 litres of water.

• Mix the required quantity of HPM Heera Zinc Plus in water and stir well until fully dissolved.
• Spray uniformly over crop foliage for best coverage and absorption.
• Apply during the active vegetative stage or when zinc deficiency symptoms first appear.
• Repeat sprays as per crop requirement and soil condition.

When to Use

Apply HPM Heera Zinc Plus when you notice early signs of zinc deficiency in your crops. Common symptoms include yellowing or chlorosis between leaf veins, stunted growth, shortened internodes, small and narrow leaves, and poor tillering in cereals. In paddy, zinc deficiency causes "Khaira disease" — rusty brown spots on leaves.

The best time for application is during the active vegetative growth stage when the crop is rapidly developing foliage and stems. For most crops, this is 20-30 days after sowing or transplanting. A second application can be done during the flowering or early fruit development stage if needed. Foliar spray is most effective when done in the morning or late afternoon when temperatures are cooler and leaf stomata are open for better absorption.

Step by Step Usage Instructions

1. Check water quality: Use clean, soft water for best results. Avoid highly alkaline or hard water if possible.
2. Measure the dose: Take 250 grams of HPM Heera Zinc Plus for each acre of crop.
3. Mix properly: Add the powder to a small amount of water first and stir to make a slurry. Then add the remaining water (total 250 litres per acre) and mix thoroughly.
4. Fill sprayer: Pour the mixed solution into a clean knapsack or power sprayer. Strain through a fine cloth or mesh to avoid nozzle clogging.
5. Spray evenly: Apply as a fine foliar spray covering all parts of the plant, especially the leaves. Ensure uniform coverage across the field.
6. Timing: Spray in the morning (before 10 AM) or evening (after 4 PM) to avoid leaf burn from strong sunlight.
7. Clean equipment: Rinse the sprayer thoroughly with clean water after use to prevent corrosion and residue buildup.

Precautions & Safety

• Store in a cool, dry place away from moisture and direct sunlight.
• Keep out of reach of children and pets.
• Do not store near food, feed, or drinking water.
• Wear protective gloves and mask while handling and mixing the product.
• Avoid inhalation of dust and contact with eyes and skin.
• Wash hands and exposed skin thoroughly with soap and water after use.
• Do not spray during strong winds, rain, or extreme heat.
• Avoid spray drift to water bodies and non-target areas.

Side Effects & Phytotoxicity

When used at the recommended dosage and timing, HPM Heera Zinc Plus is safe for crops. Over-application or spraying during peak sunlight hours may cause leaf burn or scorching. Always follow the recommended dose of 250 gm per acre and avoid mixing with incompatible products without prior testing.

PHI / REI & Storage

• Shelf Life: 2 years under normal storage conditions (cool, dry place).
• Storage: Keep in a sealed container away from moisture, heat, and direct sunlight.
