About Plant Growth Regulators (PGR)

Plant growth regulators (PGRs) are compounds used in very small quantities to influence how a crop grows, flowers and sets fruit. They act like the plant's own hormones or adjust them. Depending on the active ingredient, they can help with flowering, fruit set, fruit size, ripening, root growth or controlling excess vegetative growth.

BigHaat offers a wide range of plant growth regulators from leading brands, including auxins, gibberellins, cytokinins, ethylene releasers, growth retardants and brassinosteroids. They come in liquid and powder formulations, in pack sizes from 10 ml to 5 litres. Farmers can choose the right PGR based on the crop, growth stage, purpose of use, active ingredient and the dose recommended on the label.

Uses & Benefits of Plant Growth Regulators

• Better flowering: Certain PGRs can encourage uniform flowering and may reduce flower and bud drop in crops such as chilli, tomato and cotton.
• Improved fruit set and retention: They can help more flowers turn into fruit and may reduce early fruit drop.
• Bigger fruit and grain size: Gibberellin-based products may improve cell elongation, which can support better fruit size and quality.
• Control of excess vegetative growth: Growth retardants can check unwanted shoot growth so the crop puts more energy into flowers and fruit.
• Uniform ripening and colour: Ethylene releasers can support even ripening and colour development in fruits.
• Stronger crop under stress: Brassinosteroids and triacontanol may help crops recover from heat, drought or transplant stress.
• Higher yield and market value: Used at the right stage and dose, PGRs can improve both yield and produce quality.

Usage Tips for Plant Growth Regulators

• Identify the crop stage and the exact purpose, such as flowering, fruit set, size, ripening or growth control, before choosing a product.
• Use only the dose recommended on the label. PGRs work at very low concentrations, and overdosing may cause leaf curling, flower drop or stunted growth.
• Spray in the early morning or late evening, and avoid spraying just before rain.
• Use clean water and a properly calibrated sprayer for even coverage.
• Do a small jar test before tank mixing with fertilizers or pesticides.
• Wear gloves and a mask while handling. Store products in a cool, dry place away from sunlight and children.

Types of Plant Growth Regulators and What They Do?

• Auxins (NAA): Help reduce flower, bud and fruit drop, and can support rooting and fruit set. Examples: Planofix Plant Growth Regulator, Katyayani Alpha Naphthyl Acetic Acid.
• Gibberellins (Gibberellic Acid): Promote cell elongation, shoot growth and fruit size, and may help break seed dormancy. Examples: Hoshi Growth Regulator, Utkarsh Bhim, Katyayani Gibberellic Acid.
• Cytokinins: Promote cell division, lateral branching and flower retention, and can support fruit set and stress tolerance. Example: Tapas VitaInject.
• Ethylene Releasers (Ethephon): Support uniform ripening, colour development and flower induction in certain crops. Example: Ethrel Plant Growth Regulator.
• Growth Retardants (Paclobutrazol, Chlormequat Chloride): Slow down excess vegetative growth so the plant diverts energy to flowering and fruiting. Examples: Cultar Plant Growth Regulator, Agriventure Kasher, Lihocin Growth Regulator, Hifield Lihoguard.
• Brassinosteroids (Homobrassinolide): Support cell division and flowering, and help the crop handle stress. Example: Katyayani Homobrassinolide 0.04% W/W.
• Triacontanol and Nitrophenolates: Can improve photosynthesis, plant vigour and overall growth. Examples: Silver Crop Meerasil, Greenpeace Agro Atonix.

How to Choose the Right Plant Growth Regulator?

• Start with the purpose: For flower and fruit drop, NAA is commonly used. For size and elongation, farmers use gibberellic acid. For excess growth, paclobutrazol or chlormequat chloride, and for ripening, ethephon.
• Check the crop on the label: Use only a product whose label lists your crop.
• Match the crop stage: Most PGRs work only at a specific stage, such as pre-flowering, flowering or fruit development.
• Compare active ingredient and strength: Several brands sell the same active ingredient in different concentrations, so compare the dose per acre, not just the pack price.
• Choose the right pack size: Pick a pack based on your crop area and the number of sprays needed in the season.

FAQs

What are plant growth regulators used for?

Plant growth regulators are used to influence specific crop processes such as flowering, fruit set, fruit size, ripening, rooting and control of excess vegetative growth. Used at the right stage and dose, they can help improve yield and produce quality.

What is the difference between a plant growth regulator and a growth promoter?

A plant growth regulator contains hormone-like active ingredients such as NAA, gibberellic acid or paclobutrazol, which act on a specific growth process at very low doses. Growth promoters are usually nutrient, amino acid or seaweed-based products that support overall plant vigour.

How to choose the right plant growth regulator?

Choose based on your crop, its growth stage and the result you need, such as flowering, fruit set, size, ripening or growth control. Check that the label lists your crop, and follow the recommended dose and spray timing.
