TopGrain® Dose and Spraying Guidelines
A practical guide to dose, spray preparation, surfactant and crop-specific timing.
TopGrain® is India's first dedicated Grain Filling Technology, designed specifically for paddy and wheat. It works at the physiological level to strengthen the crop's natural grain-filling process and help transfer the plant's growth potential into developing grains.
It supports efficient sugar movement and starch formation during grain development, helping the crop convert growth into yield.
TopGrain® Dose
Spray Preparation
The tank should be about half-filled with water before adding the required quantity. Agitate while bringing the total volume to the required level, mix thoroughly until the product completely dissolves, and then add non-ionic surfactant at 0.5 ml/litre of water.
Crop-Specific Timing
- Paddy: 50% Heading Stage.
- Wheat: Early Grain Filling Stage, watery ripe or early milk stage, around 7–10 days post anthesis.
