(CH-510398) 1,262,123. Pesticides bonded to carriers.  MINNESOTA MINING & MFG.  CO. 20 March, 1969 [21 March, 1968], No. 14778/69.  Heading A5E. [Also in Division Cl] A pesticidal composition for use in water for combating undesirable plants or animals therein, contains a biocidal ionic toxicant bonded by reversible ion-exchange to the surface of a water-insoluble, particulate, inert carrier, whereby the composition when dispersed in water is confined to local areas and the biocidal substance is desorbed by ionexchange to provide localized concentrations biocide.  Specified toxicants are endothal, 2,4-D, silvex, TCA, dalapon, picloram, arsenites, diquat, paraquat, cupric compounds, antimycin A, pentachlorophenol, amitrole, 2,4,5-T, 3-trifluoromethyl-4-nitrophenol; 3'-chloro-3-nitrosalicylanilide; 2',5-dichloro-4'-nitrosalicylanilide; and N,N-dimethylcocoamine.  Carriers which can be modified (e.g. coated) to provide ion-exchange properties are hydrobiotite, vermiculite, sand, talc, kaolin, titanium dioxide, clays, bentonite, mica, light SiO 2 , glass microspheres, perlite, and Al(OH) 3 modified clays, micas and vermiculites.  Ion-exchange materials specified are aluminium, magnesium, zinc, ferric and copper hydroxides, the basic salts of calcium and barium, and cross-linked polymeric quaternized polyvinyl pyridines and aminostyrenes.  Optional composition ingredients are dyestuffs, binders, herbicides, and coatings to delay release of toxicant (examples 6 and 7).  In use, expiration of CO 2 by plants and/or the pH of the aqueous medium aid(s) in release of toxicant by ion-exchange.  The biocidal effect, however, is localized and the rest of the aquatic environment is uncontaminated.  (From GB1262123 A)
