  • Patent number: 5955094
    Abstract: Intercalates formed by contacting an activated layered material, e.g., an activated phyllosilicate, with an intercalant pesticide to intercalate an intercalant pesticide between adjacent platelets of the layered material is disclosed. Sufficient intercalant pesticide is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 .ANG. (as measured after water removal to a maximum of 5% by weight water) up to about 100 .ANG., and preferably in the range of about 10 to about 45 .ANG., so that, if desired, the intercalate can be exfoliated into individual platelets. The intercalate can be combined with an organic liquid to form a viscous composition for delivery of a pesticide compound. Alternatively, the intercalate can be exfoliated prior to combination with the organic liquid. The intercalated complex also can be admixed with solid particles to provide a granular, dust, or wettable powder pesticide composition.
    Type: Grant

  • Patent number: 5639492
    Abstract: A method of increasing the nutritional value of mycotoxin-contaminated animal feed ingested by an animal by feeding the animal an acid-activated montmorillonite clay simultaneously with the mycotoxin-contaminated or ergot-contaminated animal feed. The acid-activated montmorillonite clay can be fed to the animal in any form, e.g., granular, powder, pellets and the like or can be admixed with other animal food or feed supplements, so long as the clay is present in the animal's stomach (digestive tract) at the same time as the mycotoxin-contaminated animal feed in an amount sufficient to absorb or adsorb mycotoxin from the digestive tract of the animal and thereby aid the animal in metabolic absorption of nutrients from the contaminated animal feed.
