<p>An insecticide solid or particulate is produced from a phosphoroamido(di) thioate insecticide such as acephate. The particulate insecticide is formed by melting the insecticidal solids in a substantially oxygen-free, and prefe rably moisture free, atmosphere to prevent oxygen entrainment in the resulti ng melt to inhibit later degradation upon storage. The melt is formed into g ranules, extrudates, prills, flakes, shaped briquettes, or other shapes as d esired.</p> |
