How TopGrain® Works: Four Processes

A detailed explanation of the four processes described for TopGrain®.

How TopGrain® Works: Four Processes

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.

Better Grain Filling • Improved Grain Weight • Higher Yield Potential

Four Processes Behind TopGrain®

1. Translocation

Helps move sugars from leaves to developing grains.

2. Mobilization

Mobilizes stored energy from the stem for grain development.

3. Biosynthesis

Supports starch formation inside the grain.

4. Uniformity

Supports more uniform grain filling across the panicle or ear head.

Combined Outcome

The stated outcome is fuller, heavier and more uniform grains, supporting improved yield and grain quality.

ItemInformation
CropsPaddy and Wheat
Dose25 g per acre in both paddy and wheat
Paddy timing50% Heading Stage — when 50% of primary panicles have emerged from the boot
Wheat timingEarly Grain Filling Stage — watery ripe or early milk stage, around 7–10 days post anthesis
SurfactantNon-ionic surfactant @ 0.5 ml/litre of water

How to Prepare the Spray Solution

  1. Fill the spray tank about halfway with water.
  2. Add the required quantity of TopGrain®.
  3. Agitate while bringing the total water volume to the required level.
  4. Mix thoroughly with agitation until TopGrain® completely dissolves.
  5. Add a non-ionic surfactant at 0.5 ml/litre of water.

Important: Always use the product according to the approved label, pack instructions and the advice of local agricultural experts.
