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 are disclosed. Sufficient intercalant pesticide is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 Å (as measured after water removal to a maximum of 5% by weight water) up to about 100 Å, and preferably in the range of about 10 to about 45 Å, 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.
本发明公开了通过将活化的层状材料(例如活化的叶硅酸盐)与插层剂杀虫剂接触,使插层剂杀虫剂在层状材料的相邻小板之间插层而形成的互化物。相邻小板之间吸附了足够的插层农药,使相邻小板之间的间距扩大到至少约 5 Å(按除水至最多 5%(重量)水后的测量值)至约 100 Å,最好在约 10 Å 至约 45 Å 的范围内,这样,如果需要,插层可以剥离成单个小板。夹层可以与有机液体结合,形成一种粘性组合物,用于输送农药化合物。或者,也可以在与有机液体结合之前将中间产物剥离。夹层复合物还可以与固体颗粒混合,形成颗粒状、粉尘状或可湿性粉末状农药组合物。
