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.
