Abstract The present invention relates to a method to produce suspension concentrates of pesticides, pharmaceuticals, biocides, and similar materials, using a melt emulsification process. The method is particularly applicable to pesticides which have a low water solubility. The particle size can be controlled to give particles from less than 5 microns ( mu ) to less than 1 mu .
