  • Publication number: 20160143288
    Abstract: The mixture of potassium or certain amine salts of glyphosate and dicamba allows the preparation of high-strength liquid compositions containing greater than 300 gae/L of total active ingredient loading if the pH is adjusted between about 6.0 and about 8.0. Compositions are particularly well-suited for herbicidal applications on crops that are resistant or tolerant to both glyphosate and dicamba.

    Abstract: Pest controlling compositions exhibiting enhanced pesticidal activity levels and methods for preparing the same are disclosed. In one embodiment, a method includes providing a liquid composition that includes at least one pesticide and at least one co-ingredient that enhances pesticidal activity of the composition compared to a composition dissimilar only in not having the at least one co-ingredient. The at least one co-ingredient may include at least one metal oxide, a combination of at least transition metal salt and at least one proteinaceous material or a combination of at least one proteinaceous material and at least one polymeric material. The method further includes spray drying the liquid composition to provide a solid composition. In one aspect of this embodiment, the solid composition provided by the spray drying exhibits enhanced pesticidal activity compared to the liquid composition.

  • Patent number: 8916520
    Abstract: Various microencapsulated insecticide formulations for the control of pests such as aphids and beet army worm. These formulations exhibit excellent knockdown activity towards both chewing and non-chewing pests as LD50 values for toxicity in female rats in the range of about 2,500 mgKg?1. Some of these formulations include a wall comprised of a polymer formed, for example, by an interfacial polycondensation of a water soluble monomer and a water insoluble monomer, which at least partially surround an organophosphate insecticide. In some aspects the organophosphate in the microcapsule is chlorpyrifos. The microcapsule have a diameter in the range of about 2 to about 25 micron and the wall has a thickness in the range of about 5 to about 25 nanometers.

  • Patent number: 8911758
    Abstract: Insecticide formulations having improved chemical and physical stability and related methods are disclosed. The insecticide formulations may include a plurality of microcapsules, each including at least one organophosphate insecticide (e.g., chlorpyrifos-methyl) at least partially surrounded by a polymer shell. The insecticide formulations may be used to control insect populations by singular or periodic applications. The microcapsule polymer shell of the insecticide formulations may be formed by combining a cross-linking amine and a hydrophobic monomer (e.g., an isocyanate) at a molar ratio of amine to isocyanate groups of less than about 1:1.
