Abstract

Pseudoplastic aqueous concentrates, well adapted for dilution with water to constitute precipitate-free sprayable compositions useful, e.g., for plant protection, are formulated in water from a thickening amount of a xanthan gum having a content in pyruvic acid moieties of less than about 2%, and at least one water soluble organic cationic compound, e.g., a cationic pesticide.
