सुमितोमो टॉपग्रेन पौध वृद्धि नियामक – एस-एब्सिसिक एसिड 8.3%

Grain Filling Technology for Paddy and Wheat

Sumitomo TopGrain is a specialised plant growth regulator and grain-filling technology developed for paddy and wheat. It is powered by S-Abscisic Acid 8.3% and is designed to support the crop's natural grain-filling process during the important reproductive stage.

TopGrain works at the physiological level by supporting sugar movement from leaves to developing grains, mobilisation of stored energy and starch formation inside the grain. When applied at the correct crop stage, it helps support more uniform grain development, grain weight and crop quality.

Technical Composition

Key Features of Sumitomo TopGrain

• Dedicated Grain Filling Technology: Developed specifically for improving the grain-filling process in paddy and wheat.
• S-Abscisic Acid 8.3%: Powered by a plant growth regulator involved in important crop physiological processes.
• Sugar Translocation Support: Helps move sugars produced in leaves toward developing grains.
• Energy Mobilisation: Supports mobilisation of stored energy from plant stems during grain development.
• Starch Formation: Supports starch biosynthesis within developing grains.
• Uniform Grain Development: Helps promote more uniform filling across the panicle or ear head.
• Crop Quality Support: Supports grain size, weight, test weight and marketable produce quality.

Benefits of TopGrain

• Supports enhanced grain filling.
• Helps reduce partially filled and chaffy grains.
• Supports better grain weight and grain size.
• Helps reduce shrivelled and immature grains.
• Supports more uniform grain development.
• Can contribute to bolder and heavier grains under suitable crop conditions.
• Supports important grain-quality parameters such as test weight.
• Helps convert existing crop growth potential into marketable grain development.

How Sumitomo TopGrain Works

Recommended Crops and Application Timing

TopGrain Application in Paddy

For paddy, Sumitomo recommends TopGrain at 25 g per acre during the 50% heading stage. This is the stage when approximately half of the primary panicles have emerged from the boot.

Application at the correct heading stage is important because this period marks the transition toward active grain development and subsequent grain filling.

TopGrain Application in Wheat

For wheat, Sumitomo recommends TopGrain at 25 g per acre during the early grain-filling stage.

The recommended stage is when kernels are at the watery-ripe to early-milk stage, approximately 7–10 days after anthesis. Correct timing helps position the application during active grain development.

Mixing and Spraying Method

1. Fill the spray tank approximately halfway with clean water.
2. Add the required quantity of TopGrain to the spray tank.
3. Agitate the solution continuously while adding the remaining water.
4. Mix thoroughly until the product is properly dissolved or dispersed.
5. Add a compatible non-ionic surfactant at the recommended rate.
6. Continue agitation and apply uniformly over the crop canopy.

Non-Ionic Surfactant Recommendation

Sumitomo recommends adding a compatible non-ionic surfactant at 0.5 ml per litre of water during TopGrain spray preparation. Follow the manufacturer's mixing sequence and compatibility instructions for best application performance.

Support for Grain Filling

During grain filling, carbohydrates produced by photosynthesis must be transported efficiently from leaves and other plant tissues toward developing grains. TopGrain is designed to support this physiological process so that available assimilates can be utilised more effectively during grain development.

Proper grain filling can support grain weight, size and uniformity when the crop also receives adequate nutrition, water and other agronomic inputs.

Support for Grain Weight and Size

TopGrain supports the transfer and utilisation of crop assimilates during the grain-development stage. Sumitomo states that this can help reduce partially filled, shrivelled and immature grains while supporting bolder and heavier grain formation.

Actual crop response will depend on variety, weather, irrigation, nutrient availability and overall crop health.

Support for Grain Quality

Uniform and well-filled grains are important for produce quality and marketability. Sumitomo states that TopGrain supports grain size, grain weight, test weight and more uniform grain development.

In paddy, uniform grain development may also support milling-related quality characteristics under suitable crop-management conditions.

Best Time to Use TopGrain

• Paddy: Apply at the 50% heading stage.
• Wheat: Apply at the early grain-filling stage.
• Apply only when the crop is actively developing and adequately supplied with water and nutrition.
• Avoid delaying the spray substantially beyond the recommended physiological stage.

Important Crop Management Points

• Use the recommended dose of 25 g per acre.
• Correct crop stage is important for TopGrain performance.
• Maintain balanced NPK and micronutrient nutrition.
• Ensure adequate irrigation during grain development.
• Manage pests and diseases that can reduce green leaf area and grain filling.
• Use the recommended non-ionic surfactant during spray preparation.
• Do not treat TopGrain as a substitute for normal crop nutrition or irrigation.
