HPM 24 Karat is a plant growth regulator by HPM Chemicals and Fertilizers Ltd., formulated as a unique combination of Gibberellic Acid 0.001% L and natural seaweed extracts. 24 Karat plant growth regulator 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 in HPM 24 Karat contribute natural cytokinins, alginic acids, and micronutrients that further support physiological efficiency and stress tolerance. It is suitable for foliar application across all major crops, including Grapes, Banana, Sugarcane, Paddy, Cabbage, Onion, Brinjal, and Cotton.
Key Features & Benefits of HPM 24 Karat:
Stimulates Cell Division and Elongation: The 24 karat fertilizer drives internodal stretching and cell expansion, increasing plant height, stem length, and overall vegetative growth.
Reduces Drops: HPM 24 Karat fertilizer regulates the GA:ABA hormonal balance, helping the plant retain more flowers and set more fruits, directly improving yield per acre.
Improved Photosynthesis: The seaweed extracts in this 24 karat plant growth regulator improve leaf area development and chlorophyll content, resulting in more efficient photosynthesis and stronger crop growth.
Stronger Root System: HPM 24 Karat fertilizer promotes root initiation and development, giving the crop better access to water and nutrients from the soil, supporting plant health across all growth 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 from the start.
Uniform Flowering and Fruit Set: Regular application of this 24 karat fertilizer improves the uniformity of flowering, leading to consistent fruit set and more even fruit sizing across the crop.
Stress Tolerance: Natural seaweed extract compounds help crops better handle drought, heat, and other environmental stress, reducing yield loss during difficult growing conditions.
Improves Fruit Quality: HPM 24 Karat improves the taste, colour, and size of fruits, enhancing marketability and overall produce quality at harvest.
HPM 24 Karat Uses — Suitable Crops:
HPM 24 Karat covers a wide range of crops across all farming systems:
Fruit Crops: Grapes, Banana, Mango, Papaya, Citrus, Pomegranate, Guava

Flowers: All flowers grown for export and commercial markets
Plantation Crops: Coffee, Tea, Coconut
HPM 24 Karat Dose — Recommended Dose:
The HPM 24 Karat dosage per litre is 1.5–2 ml per litre of water for foliar spray across all recommended crops and growth stages.
Application Method | Dose Per Litre | Per 15L Pump | Timing |
|---|
Foliar Spray | 1.5–2 ml per litre | 22–30 ml per 15L pump | At vegetative, flowering, and fruit development stages |
How To Use HPM 24 Karat:
Measure 1.5–2 ml of HPM 24 Karat per litre of water required for the spray volume.
Add the measured quantity to the sprayer tank, filled halfway with clean water.
Mix well until fully blended, then fill the tank with the remaining water.
Spray evenly on both upper and lower leaf surfaces for complete coverage across all plant parts.
Apply the first spray at the vegetative stage to support early growth and root development.
Apply the second spray at the pre-flowering stage to reduce flower drop and improve fruit set.
Apply the third spray at the fruit development stage to improve fruit size, colour, and quality.
Always spray during early morning or late evening to avoid evaporation losses and ensure maximum absorption.
Best Time to Apply:
Spray HPM 24 Karat in the early morning or late evening. Apply at the vegetative, pre-flowering, and fruit development stages for the strongest growth and yield response across all crop types.
Frequency of Application & Re-Entry Period:
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.
Re-Entry Period: HPM 24 Karat is a low-toxicity plant growth regulator. No strict re-entry restriction applies. Allow foliar spray to dry on leaves before re-entering the field.
Tank-Mix Compatibility: Compatible with most foliar fertilizers and micronutrient sprays. Always perform a compatibility jar test before mixing with any unfamiliar product.
Safety Precautions & Handling:
Wear gloves, a face mask, and protective clothing when mixing and spraying HPM 24 karat.
Do not use kitchen utensils for measuring or preparing the spray solution.
Avoid contact with skin and eyes — rinse immediately with clean water if contact occurs.
Do not eat, drink, or smoke during mixing or application.
Keep away from children, pets, food, and water sources at all times.
Dispose of empty containers as per local agricultural waste guidelines.

Frequently Asked Questions (FAQs) — HPM 24 Karat:
Q1. What is HPM 24 Karat used for?
This plant growth regulator is used to stimulate plant growth, improve photosynthesis, strengthen the root system, reduce flower and fruit drop, and enhance the overall quality and yield of crops. It is suitable for Grapes, Banana, Sugarcane, Paddy, Cabbage, Onion, Cotton, and all major vegetable, fruit, and cereal crops.
Q2. How does Gibberellic Acid in this 24 karat plant growth regulator improve crop yield?
Gibberellic Acid (GA3) stimulates cell division and elongation in the plant, increasing internode length, leaf area, and root development. It also regulates the GA:ABA hormonal ratio, preventing premature flower and fruit drop. Combined with seaweed extracts in HPM 24 Karat, it further boosts enzymatic and metabolic activity for stronger crop performance.
Q3. When should I apply this 24 Karat fertilizer for maximum results?
Apply this 24 karat fertilizer at three key crop stages — vegetative growth, pre-flowering, and fruit development. The vegetative spray establishes a strong root and canopy base, the pre-flowering spray improves flower retention, and the fruit development spray improves fruit size and quality. Always apply during cool morning or evening hours.
Q4. Can HPM 24 Karat be used on all crops?
Yes. It is formulated for broad use across all major crop types like vegetables, fruits, cereals, plantation crops, and flowers. Follow the recommended dose of 1.5–2 ml per litre for all crops and adjust the timing based on the target growth stage.
