Sumitomo Sumi Blue Diamond is a plant growth regulator formulated with Gibberellic Acid 0.1% GR. It works by delivering Gibberellic Acid 0.1% GR directly into the paddy crop at the most critical early stage of growth, stimulating cell division and elongation from within, leading to healthier crops that yield better. The Sumitomo Sumi Blue Diamond also improves crop stress resistance and offers great compatibility for the best results.
Key Features and Benefits of Sumi Blue Diamond:
Increases Tiller Count: Sumitomo Sumi Blue Diamond stimulates early tillering, which leads to increased yields, especially in paddy.
Improves Overall Growth: Gibberellic Acid 0.1% GR activates the complete development of the paddy plant from early stages.
Stress Resistant: Sumitomo Sumi Blue Diamond helps plants recover faster from adverse weather like excess heat, flooding, and strong winds.
Safe to Use: Sumitomo Sumi Blue Diamond is safe for the paddy crop, the farmer, and the environment when applied at the recommended dose.
High Compatibility: This Gibberellic Acid 0.1% GR formula can be mixed with all types of fertilizers without any adverse effects.
Sumi Blue Diamond Uses — Suitable Crops:
Sumi Blue Diamond Uses are focused on Paddy as the primary crop, with benefits across other major field crops:
Primary Crop: Paddy (Rice) — all varieties, transplanted crop
Other Suitable Crops: Corn (Maize), Soybean, Cotton, Wheat, Sugarcane
Key Use Stage: 15–20 days after transplanting for Paddy — the maximum tiller generation period
Sumitomo Sumi Blue Diamond Dose — Recommended Dose:
The Sumi Blue Diamond Dosage is 5 kg per acre — broadcast directly over the paddy field 15–20 days after transplanting.
Crop | Application Method | Dose Per Acre | Timing |
Paddy (Rice) | Broadcast (with sprinkles) | 5 kg | 15–20 days after transplanting |
Other Field Crops | As per label | As per label | Seedling or early vegetative stage |
How To Use Sumitomo Sumi Blue Diamond:
Read the label instructions carefully before using Sumi Blue Diamond.
Measure 5 kg of Gibberellic Acid 0.1% GR per acre accurately using a weighing scale.
Apply by broadcasting — scatter the granules uniformly across the entire paddy field surface using a hand-operated sprinkle broadcaster for even distribution.
Apply 15–20 days after transplanting — this is when tiller emergence is most active, and the crop responds most strongly to Gibberellic Acid stimulation.
Do not use the foliar spray method for Sumi Blue Diamond — broadcast application only gives the correct dose distribution over the paddy field.
Ensure adequate field water level is maintained at the time of application for best granule contact with the paddy root zone.
For best results, use only the recommended dose — do not exceed 5 kg per acre.
Wear protective gear to avoid contact with skin and eyes during handling and application.
Best Time to Apply:
Apply Sumitomo Sumi Blue Diamond 15–20 days after paddy transplanting — this is the peak tiller initiation window when the crop's response to Gibberellic Acid is strongest. Maximum tiller generation in rice typically occurs between 30–40 days after transplanting, so early application of Sumi Blue Diamond at the 15–20 day mark sets the stage for maximum productive tiller development.
Frequency of Application and Re-Entry Period:
Frequency of Application: One well-timed application at 15–20 days after transplanting is sufficient per crop season — the effect of Gibberellic Acid 0.1% GR on tiller initiation and development is established through a single broadcast application.
Re-Entry Period: Sumi Blue Diamond is completely safe. No strict re-entry restriction applies after broadcast application. Standard precautions are adequate.
Compatibility: Can be mixed with all types of fertilizers. Perform a small jar test before combining with any unfamiliar pesticide or herbicide.
Safety Precautions and Handling:
Read the label instructions carefully before using Sumi Blue Diamond.
Wear protective gear — gloves, goggles, and a mask — to avoid contact with skin and eyes.
Do not eat, drink, or smoke during mixing or application.
Seek medical attention immediately if accidental contact or ingestion occurs.
Keep Gibberellic Acid 0.1% GR out of reach of children and pets.
For agricultural use only.
Dispose of empty containers per local waste guidelines.
