Product Description:

Plant growth regulators (PGRs) are chemical compounds employed to manipulate plant development, including enhancing branching, inhibiting shoot elongation, promoting recurrent flowering, reducing excessive fruiting, or modifying fruit ripening.

The five main plant growth regulators encompass auxins, cytokinins, gibberellins, abscisic acid, and ethylene. Each of these regulators operates distinctly. For example, auxins trigger callus formation, while cytokinins promote cellular division.

• Registering a PGR as a biopesticide in the US is a well-defined process.

• It involves obtaining approval through the Environmental Protection Agency's (EPA) Biopesticides and Pollution Prevention Division (BPPD).

• Separate registrations as a pesticide at the state level are also necessary.

Active Ingredient:

Plant growth regulators, also known as hormones, control growth at various levels in plants. The included regulators are:

• Auxins
• Gibberellins
• Cytokinins
• Abscisic acid
• Ethylene

Auxins, Gibberellins, and Cytokinins are classified as plant growth promoters.

How to Use:

PGRs need to be diluted according to the instructions provided on the bottle before being applied to your lawn. After dilution, they should be watered into the lawn at least 6 hours before or after mowing. It's crucial to monitor the growth rate of your turf in comparison to the rate of PGR application. Be sure to keep a record of the dilution and application rate for reference.

Recommended Crops:

• Dosage for Hoshi: 25-30 ml per pump (15 liters) or 250 ml per acre
• Paddy, Cotton, Sugarcane, Groundnut, Brinjal, Bhindi, Grapes, Potato, Cabbage, Cauliflower, Tea, Mulberry.

How and When to Apply:

• PGRs are most effective when applied under conditions of:

1. High humidity
2. Cool temperatures
3. Minimal air movement
4. Low light

• These conditions, especially for sprays, slow evaporation of PGR solution from the leaves.

• Apply on cloudy days.

• Growers should consider combining:
•  Residual fertilizer
•   PGR application

• This combination enhances the quality of container annuals, offering premium, value-added products.

• Plant growth regulators are typically administered as sprays or drenches.

• Foliar spray applications are predominant, given growers' familiarity with spraying in greenhouses.

• Growers utilize media drenches via traditional drench methods or the watering-in technique.

Features of the Product:

Plant growth regulators (PGRs) refer to organic compounds, excluding nutrients, which exert influence on the physiological functions of plants at low concentrations, as stated in "Climate Change and Crop Stress" (2022).

• Plant growth regulators are increasingly popular due to their ability to enhance yield and bud size.

• More growers are opting to artificially incorporate them into their crops.

• PGRs enable modification of plant morphology to suit reduced spaces or shorten growth cycles.

• Auxins, cytokinins, and gibberellins are among the most commonly used PGRs in commercial and greenhouse production. Plant growth regulators (PGRs) offer cost savings.

• PGRs can reduce water and nutrient requirements.

• They decrease labor by optimizing plant growth.
