Abstract

A microparticle composition comprising saflufenacil, wherein saflufenacil is present in the form of microparticles, which comprise solid saflufenacil, which is surrounded or embedded by an aminoplast polymer, which is a polycondensation product of one or more amino compounds and one or more aldehydes, and further comprising at least one lignin based sulfonic acid A, such as lignosulfonic acid, ethoxylated lignosulfonic acid or oxidized lignins, wherein said lignosulfonic acid A has an average molar weight MW of at least 10,000 Da.
