Abstract: Granulated, water-soluble, hygroscopic product with an average diameter 200-2000 mu m, consisting of particles which are agglomerations of finer product particles having an average diameter 5-200 mu m and which are coated with a product layer. Also claimed is the preparation of the granulate by fluidised bed granulation, by spraying an aqueous solution or dispersion of the hygroscopic product onto the bed in counter-current to heated gases, and controlling the temperature, and quantity of gas, spray rate of the product and concentration of the product in the solution or dispersion so that the product moisture content during granulation is ≤ 50% higher than the residual moisture of the final granulate. Pref. the granulate is used to deliver a plant protection substance from: bentazone salts, or salts of 2,4-dichlorophenoxyacetic acid, 2-(2,4-dichlorophenoxy)propionic acid, 2,4,-dichlorophenoxybutyric acid, 2-methyl-4-chlorophenoxyacetic acid, 2-(2-methyl-4-chlorophenoxy)propionic acid, 2-methyl-4-chlorophenoxypropionic acid, mepiquat salts, esp. mepiquat chloride, chloromequat salts, esp. chloromequat chloride, sethoxydim, cycloxydim, 2-(1-(3-chloroallyloxy)iminopropyl)-5-(tetrahydropyran-4-yl)-3-hy droxycyclohex-2 -enone and salts of acifluorfen; most pref. is sodium bentazone or potassium bentazone with a bulk weight of at least 600 g/l.

Abstract: A finely divided mixt. of an amphiphilic polymer and a polycarboxylate is prepd. by: (i) mixing: (a) an aq. dispersion or colloidal aq. soln. of an amphiphilic polymer; and (b) an aq. soln. of a polycarboxylate, in ratio by wt. of (a):(b) of 1:1-20, as solids; or by: (ii) dispersing an amphiphilic polymer in an aq. soln. of a polycarboxylate and spray-drying the dispersion to a finely divided polymer mixt.. Also claimed is a polymer mixt. with grain size 20 mu m - 3 mm.

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.
