HPM 24 Karat Plant Growth Regulator - Gibberellic Acid 0.001% L with Seaweed Extracts

HPM 24 Karat is a plant growth regulator developed by HPM Chemicals and Fertilizers Ltd., formulated as a unique combination of Gibberellic Acid 0.001% L and natural seaweed extracts. This liquid formulation works by stimulating cell division and elongation in plants, increasing stem length, improving root development, boosting photosynthesis, and regulating the GA:ABA hormonal ratio to reduce flower and fruit drop. The seaweed extracts contribute natural cytokinins, alginic acids, and micronutrients that further support physiological efficiency and stress tolerance in crops.

HPM 24 Karat is suitable for foliar application across a wide range of crops including fruits like Grapes, Banana, Mango, Papaya, Citrus, Pomegranate, and Guava; vegetables like Cabbage, Onion, Brinjal, Tomato, Okra, Capsicum, and Potato; cereals and cash crops like Paddy, Sugarcane, Cotton, Wheat, and Maize; plantation crops like Coffee, Tea, and Coconut; as well as all commercial flowers. It helps farmers achieve better seed germination, uniform flowering, improved fruit set, and higher quality produce with better marketability.

Key Benefits

• Stimulates cell division and elongation: Drives internodal stretching and cell expansion, increasing plant height, stem length, and overall vegetative growth for stronger crop establishment.
• Reduces flower and fruit drop: Regulates the GA:ABA hormonal balance, helping plants retain more flowers and set more fruits, directly improving yield per acre.
• Improves photosynthesis: Seaweed extracts improve leaf area development and chlorophyll content, resulting in more efficient photosynthesis and stronger crop growth.
• Strengthens root system: Promotes root initiation and development, giving crops better access to water and nutrients from the soil for healthier growth across all stages.
• Better seed germination: Gibberellic Acid mobilises food reserves in seeds, breaking dormancy and speeding up germination for a more uniform and vigorous crop stand.
• Uniform flowering and fruit set: Regular application improves the uniformity of flowering, leading to consistent fruit set and more even fruit sizing across the crop.
• Improves fruit quality: Enhances the taste, colour, and size of fruits, improving marketability and overall produce quality at harvest.
• Stress tolerance: Natural seaweed extract compounds help crops better handle drought, heat, and other environmental stress, reducing yield loss during difficult growing conditions.

How It Works

HPM 24 Karat works through a dual-action mechanism combining Gibberellic Acid (GA3) and natural seaweed extracts. Gibberellic Acid is a natural plant hormone that stimulates cell division and cell elongation in plant tissues. When applied as a foliar spray, it is absorbed through the leaf surface and transported to growing points such as shoot tips, young leaves, and developing fruits. At these sites, GA3 promotes internodal stretching, which increases stem length and overall plant height, and stimulates leaf area expansion for better light capture.

The Gibberellic Acid also plays a critical role in regulating the GA:ABA (Gibberellic Acid to Abscisic Acid) hormonal balance in the plant. By maintaining a favourable GA:ABA ratio, the product helps prevent premature flower and fruit drop, allowing more flowers to develop into fruits. Additionally, GA3 mobilises stored food reserves in seeds during germination, breaking seed dormancy and promoting faster, more uniform emergence.

The natural seaweed extracts in HPM 24 Karat complement the action of Gibberellic Acid by providing natural cytokinins, alginic acids, and trace micronutrients. Cytokinins support cell division in roots and shoots, alginic acids improve soil structure around the root zone, and the micronutrients enhance overall enzymatic and metabolic activity. Together, these components improve photosynthetic efficiency, nutrient uptake, and the plant's ability to withstand environmental stress conditions.

Recommended Dosage & Application

Standard Dose: 1.5–2 ml per litre of water for foliar spray across all recommended crops and growth stages.

Crop	Application Stage	Dosage per Acre
Grapes	At flowering and berry development	200–250 ml per acre
Banana	At shooting and fruit development stage	200–250 ml per acre
Sugarcane	Tillering stage	250 ml per acre
Paddy	Panicle initiation stage	200 ml per acre
Cabbage & Onion	Vegetative to head/bulb formation	150–200 ml per acre
Brinjal & Cotton	At flowering and fruiting stage	200–250 ml per acre

Per 15-litre pump: 22–30 ml per pump

Frequency of Application: Apply 2–3 times per season — at the vegetative stage, pre-flowering stage, and fruit development stage. Do not exceed the recommended dose as excess Gibberellic Acid can cause abnormal elongation and poor fruit quality.

When to Use

Apply HPM 24 Karat at three key crop stages for best results. The first spray should be done at the vegetative stage to support early growth, root development, and canopy establishment. The second spray should be applied at the pre-flowering stage to reduce flower drop and improve fruit set. The third spray should be applied at the fruit development stage to improve fruit size, colour, and overall quality.

Always spray during early morning or late evening to avoid evaporation losses and ensure maximum absorption by the leaves. Avoid spraying during peak sunlight hours or when rain is expected within 4–6 hours of application.

Step by Step Usage Instructions

1. Measure 1.5–2 ml of HPM 24 Karat per litre of water required for the spray volume.
2. Fill the sprayer tank halfway with clean water.
3. Add the measured quantity of HPM 24 Karat to the tank.
4. Mix well until fully blended, then fill the tank with the remaining water.
5. Spray evenly on both upper and lower leaf surfaces for complete coverage across all plant parts.
6. Apply the first spray at the vegetative stage to support early growth and root development.
7. Apply the second spray at the pre-flowering stage to reduce flower drop and improve fruit set.
8. Apply the third spray at the fruit development stage to improve fruit size, colour, and quality.
9. Always spray during early morning or late evening for best absorption.

Compatibility

HPM 24 Karat is compatible with most foliar fertilizers and micronutrient sprays. It can also be combined with most insecticides, fungicides, and soluble fertilizers. Always perform a compatibility jar test before mixing with any unfamiliar product. Avoid mixing with strong alkaline solutions.

Precautions & Safety

• Wear gloves, a face mask, and protective clothing when mixing and spraying HPM 24 Karat.
