Abstract
Abstract A shaped solid body is described which contains insecticidal organic phosphate adsorbed on a solid adsorbent, the adsorbate being so distributed in a solid hydrocarbon base of porous texture that a major portion of the insecticide can be gradually released in vapor form from the surface of the body into the surrounding atmosphere; a process for the production of such bodies is also described. O,O-dimethyl-0-(2,2-dichlorovinyl) phosphate is preferred as the insecticidal component in such bodies.
