Chemical Encapsulation and Distribution.
Abstract
A method is presented of coating chemicals that are used in the control of insects which protects the chemicals from biodegradation and improves their distribution in insect-containing bodies of water. A fat is mixed with an appropriate solvent, surfactant and chemical to be coated and heated to a temperature at which relative homogeneity of the solution is achieved. When using a water miscible solvent, the mixture is pressure injected into a body of water as a fine mist under high pressure. A non-water-soluble solvent may be used; in such an instance a suitable solvent extracting process, such as spray drying, is undertaken before the introduction of the material into a body of water. A stable colloid containing the chemical is the final dispersion in a body of water. (Author)
