Structurants for agrochemical oil based active formulations, and in particular for use in agrochemical concentrate and diluted concentrates, for suspending solids in oil based formulations. The solids are one or more agrochemical actives and/or nutrients which are dispersed in the formulations. The structurant is polyamide formed from a dicarboxylic acid comprised from a dimer acid compound, and one or more diamine compounds. The present invention also includes methods of treating crops with such micronutrient formulations.
