Executive summary:

The particle size distribution of triasulfuron technical has been determined using laser diffraction in accordance with the CIPAC method 187 (Fraunhofer diffraction
method) using the dry-dispersion unit.
The average results, correct to three significant figures, are given below:
- Dv (10) 4.38 μm
- Dv (50) 22.2 μm
- Dv (90) 60.2 μm

Description of key information

Dv (50) = 22.2 μm, CIPAC method 187 Fraunhofer diffraction method, Ravikumar 2022.
