The use of self‐sustained gas‐producing reactions of such materials as ammonium nitrate, guanidine nitrate, and nitroguanidine, with various sensitizers, for the dispersion of benzene hexachloride and other pesticides is described. The optimum mixtures of gas‐producing component, sensitizer, and pesticide to give easy initiation, complete propagation, and high volatilization‐efficiency have been investigated. A laboratory method for the biological assessment of the smoke deposits is given. The particle size, persistence, and settling time of these deposits, their distribution over horizontal, inverted horizontal, and vertical surfaces, and the relative toxicity of different types of surface have been studied. The design for manufacture of smoke generators based on these principles is discussed.
