Sumitomo Progibb is a strong Gibberellic Acid plant growth regulator. It works by breaking seed dormancy, activating growth enzymes, and boosting cell elongation and division. The Sumitomo Progibb offers a strong formula that is easy to use, making it very beginner-friendly. It promotes quick crop growth while improving yield quality and quantity for the best harvests.
Key Features and Benefits of Sumitomo Progibb:
Strong Formula: Sumitomo Progibb offers a strong formula that contains 40% GA3 in a non-dusty, free-flowing granule formulation.
Better Growth: Progibb Plant Growth Regulator stimulates both cell elongation and cell division for quicker and healthier growth.
Increased Yields: The Progibb plant growth regulator speeds up and strengthens flowering and fruiting, providing profitable yields.
Reduced Fruit Drops: Sumitomo Progibb helps retain developing fruit on the plant longer, reducing crop loss and ensuring better yields.
Easy to Use: Sumitomo Progibb dissolves completely in water for simple application, making it easy to mix and apply.
Progibb Uses — Suitable Crops:
Progibb Uses cover a very wide range of crops across all categories:
Fruit Crops: Grapes (cluster stretching, thinning, berry sizing), Citrus (fruit size, June drop reduction), Banana, Pineapple, Sweet Cherry, Grapefruit, Apple
Vegetables: Brinjal, Celery, and other vegetables for improved size and uniformity
Field Crops: Rice/Paddy (taller, more productive plants), Sugarcane (stalk elongation, juice yield)
Flowers and Ornamentals: All flower crops for better bloom size and uniformity
All Other Crops: Sumitomo Progibb is effective across fruits, flowers, and vegetables broadly
Sumitomo Progibb Dose — Recommended Dose:
The Progibb Dose Per Litre is 0.11–0.55 gm per 10 litres of water (0.011–0.055 gm per litre) — the exact dose varies significantly by crop, application method, and growth stage. Broadly, 2.5–5 gm per acre in 200–280 litres of water per acre covers most field crop applications.
Crop | Dose Per Acre | Method | Timing |
|---|
Grapes (Cluster Stretching) | 3–16.8 gm | 2 blanket sprays | As per growth stage |
Grapefruit | 100–200 gm | 1 directed spray | Full bloom and pre-harvest |
Brinjal | 2 gm | 1 dipping application | As per label |
Rice / Paddy | 5 gm | Foliar spray | Tillering and panicle initiation |
Other Crops | 2.5–5 gm | Foliar spray | Active vegetative and flowering stages |
How To Use Sumitomo Progibb:
Read the crop-specific dose and timing guidelines on the label before mixing — Sumitomo Progibb dose varies significantly between crops and application purposes.
Measure the required quantity of Progibb plant growth regulator accurately using a fine-gram weighing scale — small dose variances can affect crop response at these concentrations.
Drop the granules directly into the required volume of water — Sumitomo Progibb dissolves instantly without any additional mixing or agitation.
Add the solution to the spray tank and fill to the required water volume per acre before spraying.
Apply as a foliar spray covering all plant surfaces — or as a dipping solution for specific crops and stages as per label guidance.
Always apply during cool morning or evening hours — avoid spraying in high heat or strong wind that reduces absorption and increases drift risk.
Apply at the exact recommended crop growth stage — the timing of Progibb plant growth regulator application is the single biggest factor in getting the best crop response.
Keep spray equipment clean after each use to prevent residue build-up.
Best Time to Apply:
Apply Sumitomo Progibb in the early morning or late evening on calm, mild weather days. Always apply at the correct crop stage — for fruit size improvement in Grapes and Citrus, the critical windows are at bloom and just after fruit set. Off-timing applications significantly reduce the quality of the response.
Frequency of Application and Re-Entry Period:
Frequency of Application: Frequency varies by crop and purpose — most applications involve 1–2 targeted sprays per season at the crop stage-specific windows. Always follow the label guidance for each crop.
Re-Entry Period: Sumitomo Progibb is an organic, naturally occurring compound. No strict re-entry restriction applies. Standard post-spray drying precautions are sufficient.
Compatibility: Compatible with most water-soluble fertilizers and crop inputs. Always do a jar test before combining with unfamiliar products. Avoid mixing with strongly alkaline solutions.
Safety Precautions and Handling:
Wear gloves and a face mask as a general precaution while measuring and applying Sumitomo Progibb.
Avoid contact with skin and eyes — rinse with clean water immediately if contact occurs.
Do not exceed the recommended dose for the specific crop and stage — overdosing can cause excessive elongation and reduce crop quality.
