What are plant growth regulators?
A plant growth regulator, also called a PGR, is a substance that changes how a plant grows and develops. It may imitate the plant's own hormones, or it may change the way those hormones behave. Hormones are the plant's internal messengers: they tell roots when to branch, buds when to open, seeds when to wake up and fruit when to ripen.
In everyday farming, the term covers a wider set of products. When a grower asks for a PGR for plants, a plant growth promoter is often what they mean: a natural product based on humic acid, seaweed or amino acids that backs the plant's own processes. These are not synthetic hormones, and they do not replace fertilizers. We explain each kind below to keep the differences clear.
Categories of Plant Growth Regulators
As Plant Growth Regulator (PGR) Suppliers, Manufacturers, Dealers, Traders and Exporters in Chennai, we help agricultural businesses understand the different plant growth regulator categories and explore suitable crop growth support products.
Plant growth regulators have two sources: natural plant hormones (called phytohormones) and man-made chemicals that copy or influence them. Scientists sort them into five classical families and a handful of newer ones.
The five groups:
| Group | What it does | Examples | Role in the field |
|---|---|---|---|
| Auxins (promoters) | Drive cell elongation, root formation and apical dominance, and help keep fruit and leaves on the plant | Indole-3-acetic acid (natural), NAA and other synthetic auxins | Rooting of cuttings and less premature drop |
| Gibberellins (promoters) | Lengthen stems, break seed and bud dormancy, trigger germination and flowering, and help produce seedless fruit | Gibberellic acid (GA3) | Germination, fruit size and control of flowering |
| Cytokinins (promoters) | Stimulate cell division, push lateral buds, support chlorophyll and delay leaf ageing | Kinetin and zeatin (natural), synthetic cytokinins | Branching and longer-lasting green leaves |
| Abscisic acid (inhibitor) | The plant's stress hormone, which closes leaf pores to save water and promotes dormancy | Abscisic acid (ABA) | Drought response and dormancy of seeds and buds |
| Ethylene (promoter and inhibitor) | A gas hormone that controls fruit ripening, leaf and fruit drop, and ageing | Ethylene (natural), ethephon (synthetic) | Ripening and abscission |
Newer and specialised hormone classes:
- Brassinosteroids help with cell division, stem growth and tolerance to stress.
- Strigolactones shape shoot branching and root architecture, and help the plant communicate with soil microbes.
- Jasmonates and salicylic acid manage the plant's defence against pests and disease, and respond to physical or environmental stress.
- Polyamines, nitric oxide and karrikins have supporting roles in germination, stress signalling and tissue development.
Promoters, inhibitors and dual-action regulators
Another way to sort PGRs is by the direction of their effect. Abscisic acid mainly holds growth back so that the plant can survive stress, whereas auxins, gibberellins and cytokinins mainly promote growth. Depending on stage and tissue, ethylene works both ways. Growers also use growth retardants to keep tall crops compact, which is a separate use with its own rules.
Please note: hormone-type regulators are powerful, so they demand accurate dosing, correct timing and the right registration. Apply them only as directed on a registered label and with an agronomist's advice.
Our Plant Growth Promoter and Biostimulant Range
Pure Grow's range belongs to the plant growth promoter and biostimulant side of the field. We do not sell these products as synthetic hormones. Instead, they back the plant's own growth systems through nutrition, soil health and natural compounds:
| Our products | How they support growth |
|---|---|
| Seaweed (green and black, powder, flakes, liquid) | Small amounts of natural growth-active compounds are present in seaweed. It supports rooting, shoot growth and recovery from stress, which are the same areas where auxins and cytokinins act. |
| Humic range (potassium humate, humic granules) | Nutrient uptake by roots improves and soil structure gets better. Research also links humic substances with stronger root growth. |
| Fulvic range (fulvic acid, potassium fulvate) | These small molecules enter the plant quickly and help carry nutrients, especially micronutrients. |
| Amino acid range | Ready building blocks that save the plant energy, particularly during flowering, fruit set and stress. |
| Organic carbon | Nourishes soil life and improves soil structure, so roots stay healthier. |
How do plant growth regulators work inside plants?
Signals keep a plant running. One part releases a hormone, which travels to another part and switches a response on or off. Classical PGRs add to or change those signals. Growth promoters like ours work alongside the signals rather than over them: nutrients become easier to take up, the plant receives ready materials and the soil around the roots improves, so natural signalling can do its job properly.
These products therefore work best as an addition to a sound fertilizer program, not as a replacement.
The role of plant growth regulators in agriculture
We offer a diverse range of agricultural products that complement crop nutrition and support informed crop management practices, and we do so as Plant Growth Regulator (PGR) Manufacturers, Suppliers, Traders, Dealers and Exporters in Chennai.

Humic range
- Potassium Humate Crystal: Humic acid with potassium in a shiny, fully soluble form. Residue can block emitters in drip and fertigation, but this crystal dissolves cleanly, which makes it a popular pick there. It supports root development and nutrient uptake.
- Potassium Humate Flakes: Flakes that retain the same humic benefits while being easy to handle and quick to dissolve in a tank. Dealers and blenders who serve both soil and spray customers find it a practical choice.
- Potassium Humate Powder: A fine powder for soil application, blending and foliar use. Soil structure improves, and roots take up nutrients more effectively.
Humic granules
- Humic Bentonite Granules (Coated and Non-Coated): Humic acid is carried by bentonite clay, which also doubles as a soil conditioner. The coated grade is easier to handle and spread, and the non-coated grade is a simple, economical option. Both go on as a basal dose.
- Humic Granules (Non-Coated): A straight granular humic product for broadcast and basal use, made for growers who want to build the soil without spraying.
- Humic Shiny Ball: Smooth, round granules that spread evenly and look uniform in the pack, which suits retail packs and growers who prefer a clean, even product.
Fulvic range
- Fulvic Acid 80%: A concentrated acid with small molecules, it is absorbed readily by plants and so suits foliar spray and drip. It helps nutrients, especially micronutrients, move into the plant more easily.
- Potassium Fulvate: Soluble, quick-acting fulvic acid with potassium, meant for spray and fertigation wherever a fast, clean input is needed.
Amino acid range
- Amino Acid 80% (Soya Protein Base): This high-strength powder is made from soya protein and is meant for spray or drip use. During flowering, fruit set and stress, amino acids hand the plant ready building blocks.
- Amino Acid 50% (Soya Protein Base): The same soya-based product at a more economical strength, well suited to routine spraying and blending.
- Amino 60% Liquid (Medium Thick): Ready-to-use liquid with a medium consistency that pours easily and mixes fast.
- Amino 60% Liquid (Isabian Honey Thick): The same 60% strength in a thicker, honey-like liquid, for buyers who like a denser feel in the can.
Seaweed range
- Green Seaweed Powder: Dissolves readily for spray or fertigation, and supports rooting, shoot growth and stress recovery.
- Black Seaweed Powder: Dark seaweed powder used in sprays or drip lines, and often selected for fruit, vegetable and plantation crops.
- Black Seaweed Flakes: Black seaweed in flake form that dissolves easily and is convenient for bulk buyers and blenders.
- Green Seaweed (Liquid): Liquid seaweed that is ready to use for quick foliar application when time is short and no mixing is wanted.
Organic carbon and combination products
- Organic Carbon (Soil): Carbon applied to the soil to build long-term soil health, feeding soil microbes and improving structure.
- Organic Carbon 100% Soluble: Fully soluble carbon that reaches the root zone directly through drip and fertigation.
- Humic + Amino + Fulvic + Seaweed (Liquid): One liquid that combines four growth-supporting ingredients. Growers who want broad cover in a single pass, with fewer products to buy and mix, can use it as a liquid organic growth booster.
Best Plant Growth Regulator Products for Each Crop Growth Stage
We help buyers explore product options by crop development stage, intended application and product-specific recommendations, and we do so as Plant Growth Regulator (PGR) Suppliers, Dealers, Exporters, Traders and Manufacturers in Chennai.
| Your goal | Products to consider | Best time |
|---|---|---|
| Plant growth regulator for root growth | Potassium Humate, Humic Granules, Organic Carbon, Green Seaweed | Sowing, transplanting and early growth |
| Plant growth regulator for flowering | Amino Acid, Black Seaweed, Fulvic Acid | Before and during the bud and flower stages |
| Plant growth regulator for fruit development | Amino Acid, Potassium Fulvate, Black Seaweed | After fruit set and during fruit filling |
| Plant growth regulator for crop yield | Humic + Amino + Fulvic + Seaweed, Potassium Humate | Throughout the crop cycle, alongside fertilizer rounds |

| Plant growth regulator for better crop growth | Humic or Fulvic range with Organic Carbon | Early to mid growth stages |
How do you pick the best PGR for your crop?
No single plant growth regulator is best for every crop. The right choice is decided by the crop, soil, stage and method.
- Match the form to the method: Crystals, soluble powders and liquids suit drip and spray, whereas granules suit basal and broadcast use.
- Match the product to the stage: Early roots are built by humic products and organic carbon, while flowering and fruit are supported by amino acid and seaweed.
- Consider the soil. Humic and organic carbon inputs benefit sandy, low-organic soils the most.
- Keep it simple: The combination liquid saves time and tank space if one product should cover several jobs.
Unsure? Share the crop, stage and area with us, and we will propose a plan.
What is the right way to use plant growth regulators in farming?
Treat this as a general guide to plant growth regulator spray, solution and dosage. The label and technical sheet of the product you buy always come first.
| Product type | Foliar spray (per litre of water) | Soil or drip (per acre) |
|---|---|---|
| Potassium Humate (crystal, flakes, powder) | 1 to 2 g | 1 to 2 kg |
| Fulvic Acid 80% / Potassium Fulvate | 0.5 to 1 g | 250 to 500 g |
| Amino Acid 80% or 50% | 0.5 to 1.5 g | 500 g to 1 kg |
| Amino 60% Liquid | 1 to 2 ml | 500 ml to 1 litre |
| Seaweed (powder or flakes) | 1 to 2 g | 500 g to 1 kg |
| Green Seaweed (Liquid) | 2 to 3 ml | 500 ml to 1 litre |
| Humic Granules, Bentonite Granules, Shiny Ball | Not for spray | Basal, as per recommendation |
The ranges given are indicative starting points. Because crop, soil and stage affect the dose, consult our agronomist before applying.
Good habits when preparing a plant growth regulator solution:
- First dissolve powders and flakes in a little water, and then top up the tank.
- Pick the early morning or late afternoon, and never spray in strong midday sun.
- Run a small jar test before mixing with other products.
- Stay within the recommended dose. More is not better, since plant growth regulator effectiveness depends on correct dose and timing.

- Realistic Yield Expectations: Crop yield is decided by factors such as weather, irrigation, soil fertility and crop management, and no product guarantees increased production.
Combining PGR with NPK and Micronutrients
Growth promoters do not replace the main nutrients; they help the crop use them. In a sound program, micronutrients such as zinc, iron and boron go in wherever a test shows a shortage, and macronutrient (NPK) fertilizers, such as our water-soluble grades, are paired with a PGR product at the right stage. Our micronutrient range sits alongside these products.

Frequently Asked Questions
Any substance that influences plant growth, usually by mimicking or modifying natural hormones, is a plant growth regulator. In everyday farming, the term also covers plant growth promoters made from humic acid, seaweed and amino acids.
The classical groups number five: auxins, gibberellins, cytokinins, abscisic acid and ethylene. Brassinosteroids, strigolactones, jasmonates, salicylic acid and polyamines are among the newer classes.
Gibberellins are best known for breaking seed and bud dormancy and for triggering germination. Abscisic acid does the opposite and keeps seeds dormant.
Auxins support cell elongation and root formation, whereas cytokinins stimulate cell division and branching and also delay leaf ageing. Working together, the two keep root and shoot growth balanced.
Although the trade widely calls them PGRs, they are strictly plant growth promoters or biostimulants, not hormone-type regulators. They support the plant's own growth and do not replace fertilizers.
They support or alter the plant's natural signals. Roots take up nutrients better with humic and fulvic acids, seaweed supplies natural growth-active compounds, and amino acids provide ready building blocks during flowering and stress, which lets the plant's own signalling work better.
No single product is best; let the crop, soil, stage and method guide the choice. Early root growth suits humic products and organic carbon, whereas flowering and fruit suit amino acid and seaweed.
At sowing, transplanting and early growth, potassium humate, humic granules, organic carbon and green seaweed are commonly used.
Around the bud, flower and fruit-fill stages, amino acid, black seaweed and fulvic products are commonly used.
Dissolve the product in a little water and then top up the tank. Follow the label dose, spray in the early morning or late afternoon, and run a jar test before mixing with other products.
That depends on the product, crop and stage. Indicative ranges appear in the table on this page, and our team can confirm the exact dose for your case.
Not exactly. A liquid bio fertilizer usually carries living microbes, while our liquid products, including the humic, amino, fulvic and seaweed liquid, are organic growth boosters made from natural extracts. Both support crops, yet they work differently.
Yes. Macronutrient (NPK) fertilizers and growth promoters are designed to work side by side, and the promoters help the crop make better use of them.
Yes. Send us the product, quantity and destination, and we will share a quote with packing and documentation details.
Humic acid has a larger molecule and mainly improves soil and root conditions over time. Because fulvic acid is smaller, it enters the plant quickly, which makes it suitable for foliar and drip use.
