Suggested are agricultural compositions, comprising one or more esters of C6-C22 monocarboxylic acids or C2-C20 dicarboxylic acids and polyhydric alcohols selected from the group consisting of diglycerol, triglycerol, oligo- or polyglycerol and their respective alkylene oxide adducts, one or more biocides, and optionally, one or more oil components or solvents and/or one or more emulsifiers, wherein the esters are essentially free of esters of monomeric glycerol and esters of alkylene oxide adducts of monomeric glycerol. The esters are useful for forming agricultural compositions using hard water.
