Definitions

  • the present invention relates to compositions and methods related to controlling pests.
  • hydrophobic pesticidal compounds such as essential oils
  • these formulations have simply been employed to facilitate application of the pesticide directly to the pests or to the surfaces or environments inhabited by the pests.
  • Microemulsions are clear uniform liquid mixtures of oil, water and surfactant.
  • surfactant component is a wetting agent that lowers the surface tension of liquid
  • microemulsions tend to consist of a mixture that can be spread easier than other mixtures and thus provide greater surface area.
  • considerable attention has been directed toward microemulsion-based pesticidal formulations.
  • the formulation of microemulsions is far from being an exact science, as many oil based pesticides are not able to microemulsify and the interactions between oil, emulsifiers and water molecules are still not completely understood, microemulsion formulations appear to be an emerging standard for the formulation of hydrophobic pesticides in water-based carriers.
  • FIG. 1 depicts, in accordance with an embodiment described herein, a chart of percent of insects knocked down by of formulations of a blend containing the ingredients in the exemplified form of Ingredient Family 24 applied to the German cockroach.
  • FIG. 2 depicts, in accordance with an embodiment described herein, a chart of percent killed versus time by formulations of a blend containing the ingredients in the exemplified form of Ingredient Family 24 applied to the German cockroach.
  • the present disclosure relates to emulsion-based formulations of pesticides, specifically pesticidal blends of essential oils and other ingredients, that have been found to enhance the activity of the active pesticidal ingredients.
  • the activity of an ingredient may be greatly enhanced and the efficacy of the pesticide may be vastly improved.
  • enhancing the activity of a key ingredient can also be helpful in reducing the amount of active ingredients that may be required for effective pest control. This, in turn, improves the overall safety of the pesticide and may increase the likelihood of a pesticide receiving EPA approval when it becomes developed for commercial application.
  • the present disclosure relates to a dust formulation that also improves the activity of pesticidal blends that are formulated in this manner.
  • dust formulations are employed in hard-to-reach areas that are not amenable to the application of liquid sprays.
  • Commercially available dust formulations include DeltaDust and Drione®.
  • these formulations themselves have not been not known to specifically enhance the activity of the active ingredients in the dust formulations.
  • Embodiments of the invention are directed to compositions for controlling insects and methods for using these compositions.
  • Embodiments of the invention include compositions for controlling pests, which can include one or more plant essential oils and methods for using these compositions.
  • the plant essential oils when combined, can have a synergistic effect.
  • the compositions also can include a fixed oil, which is typically a non-volatile non-scented plant oil. Additionally, in some embodiments, these compositions can be made up of generally regarded as safe (GRAS) compounds.
  • GRAS generally regarded as safe
  • the term “pest” shall be used in this application. However, it should be understood that the term “pest” that encompasses a variety of life forms such as various types of animals including worms and insects, fungi, plants, protists, and monerans. As used in this application the term “insect” refers, not only to insects, but also tomites, spiders, and other arachnids, larvae, and like invertebrates. Also for purposes of this application, the term “pest control” shall refer to having a repellant effect, a pesticidal effect, or both. “Repellant effect” is an effect wherein more pests are repelled away from a host or area that has been treated with the composition than a control host or area that has not been treated with the composition.
  • “Pesticidal effect” is an effect wherein treatment with a composition causes at least about 1% of the pests to die.
  • an LC1 to LC100 (lethal concentration) or an LD1 to LD100 (lethal dose) of a composition will cause a pesticidal effect.
  • the pesticidal effect is an effect wherein treatment with a composition causes at least about 5% of the exposed pests to die.
  • the pesticidal effect is an effect wherein treatment with a composition causes at least about 10% of the exposed pests to die. In some embodiments, the pesticidal effect is an effect wherein treatment with a composition causes at least about 25% of the pests to die. In some embodiments the pesticidal effect is an effect wherein treatment with a composition causes at least about 50% of the exposed pests to die. In some embodiments the pesticidal effect is an effect wherein treatment with a composition causes at least about 75% of the exposed pests to die. In some embodiments the pesticidal effect is an effect wherein treatment with a composition causes at least about 90% of the exposed pests to die.
  • bioassay refers to a quantitative procedure used to determine the relationship between amount (or dose or concentration) of pesticide administered and the magnitude of response in the living organism.
  • KD refers to knockdown.
  • “Knockdown” is an effect wherein treatment with a composition causes at least about 1% to display reduced mobility. In some embodiments, the knockdown is an effect wherein treatment with a composition causes at least about 50% of the exposed pests to die.

  • emulsions As used herein and know to one of skill in the art, the spectrum of various types of emulsions in terms of both water out and oil out, as well as size distribution of the emulsion are incorporated in the term “emulsions,” including microemulsions. Nevertheless, in particular embodiments of the present invention the formulation agents are not such as to form a microemulsion. Embodiments encompassing all or some formulations other than microemulsions are specifically contemplated.
  • repellent effect is an effect wherein more pests are repelled away from a host or area that has been treated with the composition than a control host or area that has not been treated with the composition.
  • component of a composition refers to a compound, or a subset of compounds included in a composition, e.g., the complete composition minus at least one compound.
  • compositions of the present invention are directed to compositions for controlling pests and methods for preparing and using these compositions.
  • Compositions of the present invention can include any of the following oils, formulations, chemicals, compounds, or mixtures thereof:

  • Methyl salicylate the main constituent of the oil, is not present in the plant until formed by enzymatic action from a glycoside within the leaves.
  • Thyme oil is a natural product that can be extracted from certain plants, including species from the Labiatae family; for example, thyme oil can be obtained from Thymus vulgaris (also known as, T. ilerdensis, T. aestivus , and T. velantianus ).
  • Geraniol also called rhodinol, is a monoterpenoid and an alcohol. It is the primary part of oil-of-rose and palmarosa oil. It is used in perfumes and as a flavoring. It is also produced by the scent glands of honey bees to help them mark nectar-bearing flowers and locate the entrances to their hives. In certain embodiments, where geraniol is employed, it may be mixed with 10%, 20%, 30%, or 40% or more nerol. Commercially obtained geraniol may be designated by the amount of geraniol it contains.
