  • Publication number: 20070245937
    Abstract: A method for the subsurface application of fertilizers, biologicals, fumigants, non-fumigant pesticides or other chemicals to soil with reduced application rates. Discrete amounts of the materials are injected into the soil at numerous sites along a path during a pass through the soil. At the injection sites, the materials form diffusion patterns which may touch or overlapping with diffusion patterns of adjacent soil injections. The application of materials to soil in this manner maintains optimum efficacy with the use of the least amount of materials necessary per acre of soil.

  • Publication number: 20040259847
    Abstract: Chemically stable, insecticidally active pellets having a low moisture content and at least about 95% active ingredient are described, as well as a method for manufacturing them. The active ingredient is selected from a class of N-hydrocarboyl phosphoroamidothioate and phosphoroamidodithioate compounds as described in the specification. The pellets generally have a moisture content of about 0.5% by weight or less, preferably less than about 0.3% by weight. The pellets can be produced by one of two types of processes as described in detail, including a high pressure axial extrusion process and a low pressure basket extrusion process.
