The invention relates to solid plant protection compositions comprising:a) liquid or low melting point polyalkoxylate andb) a carrier based on relatively high molecular weight sulfonate, wherein(i) the weight ratio of liquid or low melting point polyalkoxylate to plant protection active agent is at least 1:2(ii) the proportion of liquid or low melting point polyalkoxylate, based on the total weight of the relatively high molecular weight sulfonates, is at least 30% by weight and(iii) the weight ratio of liquid or low melting point polyalkoxylate to relatively high molecular weight sulfonate is at most 3:1.The invention also relates to processes for their preparation and the use of the plant protection compositions for the treatment of plants and their habitat as well as corresponding processes, and also spray mixtures comprising such a plant protection composition.
