摘要： The invention relates to a new solid storage and marketing presentation for phytosanitary compositions based on any active substance which is little soluble in water or insoluble in water and solid at ambient temperature; these active substances are especially selected from herbicides presenting the said features; these herbicides comprise bramoxynil, ioxynil and their esters as well as. dinitroanilines, especially butralin, pendimethalin, flumetralin and oryzalin. It is in the form of flakes based on a film-forming material which is water-soluble and brittle after drying, and throughout which are dispersed especially the particles of active material. This solid storage and marketing presentation may be prepared by maly of an installation comprising a rotating drying drum (1) on which a thin layer of a dispersion (D) of particles of active substance in an aqueous solution of a film-forming material which is brittle at the dry state is applied. The parties of the surface of the drum on which is applied the dispersion (D) travel through the heated part or zone of the chamber (2) at a speed such that the dispersion is dried, shrinks and becomes detached fromthe surface of the drum (1) in forming flakes (P).
