A SLOW-RELEASED GLYPHOSATE FORMULATION WITH SUPERMOLECULAR STRUCTURE AND THE PREPARATION METHOD THEREOF

摘要

The present invention relates to a glyphosate slowly-releasing agent with supermolecular structure and its preparation method. Said invention uses anionic layer material LDH as main body, and uses glyphosate as intercalation guest, makes the mixed salt solution prepared by two soluble metal salts and alkali solution of glyphosate undergo the process of one-step assembling treatment to obtain GLY-LDHs with supermolecular structure, its chemical formula is :(M2+)1-x(M3+)x(OH)2(GLY_)al(GLY2-)a2(GLY3-)as(Bn-)b.mH2O. The mass percentage content of glyphosate pesticide in said slowly-releasing agent is 8-50%, and mass percentage content of water is 1-35%, and its release continuous effective period can be up to 0.2-24 months. It is applicable to soil whose pH value is in the range of 3-13.
