<p>Pesticidal organophosphorus compsns on a porous sintered mineral rigid support and stabilised by a salt of a carboxylic acid, an amino acid or an N-metallic deriv of a benzimidazole in which the stabilisers are produced inside the porous support by successively introducing (a) an acid and then an inorg. or org. base or a carbonate of such a base (b) the salts of two cpds which produce the stabiliser by displacement of ions, (c) one cpd being a salt and the other a benzimidazole having an H-atom or alkali metal in the 1-posn. Pref. active component is dichlorvos.</p> |
