ABSTRACT:
An at least partially water insoluble powder containing a pesticide in admixture with an inert diluent wherein the pesticide is incorporated within the powder during its formation. The powder can be manufactured by directly admixing the pesticide, i.e., an insecticide, a larvacide, a fungicide, a herbicide, etc., or mixtures thereof, with or without the aid of pre-solution in an organic diluent, into a metalloid or metallic chloride; reacting the resulting mixture in atomized form in a stream of air with an atomized water solution of ammonia or ammoniacal substance in substantially stoichiometric proportion to the chloride to produce a fume; collecting the fume as a powder; and utilizing such activated powder as a pesticide by placing the pesticide below the surface of the earth.
