Abstract: A novel design of controlled-release glyphosate with a supramolecular structure has been proposed, according to the shortage of traditional pesticide and controlled-release pesticide at present. On the basis of the concept of intercalation and assembly, glyphosate anion intercalated magnesium-aluminum layered double hydroxides(abbreviated as MgAl-LDH-gly) has been prepared by coprecipitation. According to the crystal structure, the interaction between host and guest anion, and chemical composition of MgAl-LDH-gly, orientation of glyphosate anion between the layers of MgAl-LDH-gly are given.

Key words: Supramolecular structure, Glyphosate anion intercalated magnesium-aluminum layered double hydroxide, Controlled-release fomulation of glyphosate
