Abstract: Production of a suspension (A) of at least one water insoluble solid agrochemical active agent (I) of melting point below 80 degrees C comprises: (1) suspending silicic acid-based carrier in water in the presence of an anionic dispersant; (2) heating the suspension above the temperature of (I); and (3) adding molten (I) under stirring. Production of a suspension (A) of at least one water insoluble solid agrochemical active agent (I) of melting point below 80 degrees C comprises: (1) suspending 1-40 weight.% (wt.%) silicic acid-based carrier in 40-97 wt.% water in the presence of 1-40 wt.% anionic dispersant; (2) heating the suspension above the temperature of (I); and (3) adding 1-25 wt.% molten (I) under stirring. The sum of the percentages in (1) and (3) is 100 wt.%. Independent claims are also included for: (1) A suspension (A) obtained by the above process; and (2) Production of a suspension concentrate, a water-dispersible powder or a water-dispersible granulate, which involves mixing (A) with at least one further active agent (II) and/or appropriate formulation auxiliaries, to form the suspension concentrate directly, a mixture to be dried and further processed to give the powder or a mixture to be processed to give the granulate by a drying process.
