Abstract
The present invention relates to a method for producing an aqueous suspension concentrate formulation and novel suspension concentrate formulations of the compound of formula I. The method comprises the steps a) to d) as described hereinafter: a) providing an aqueous slurry of the compound of the formula I containing the compound of formula I in the form of coarse particles dispersed in a solution of the at least one surfactant in water; b) comminuting the coarse particles in the slurry of the compound of formula I to obtain an aqueous suspension of the compound of the formula I, wherein the particles of the compound of the formula I have an volume average particle size in the rage from 3 to 10 μm, as determined by light scattering; c) keeping the suspension of step b) at a temperature in the range of 20 to 95° C., d) subjecting the suspension of step c) to a further comminution to obtain an aqueous suspension of the compound of the formula I, wherein the particles of the compound of the formula I have an volume average particle size of below 3 μm, as determined by light scattering.
