Definitions

  • the present invention is directed to increasing the stability of pest control agents that degrade after application as a result of exposure to environmental factors, and more particularly, to the use of vegetable oils, modified vegetable oils, or vegetable oil derivatives in formulations to protect the agents from the damaging environmental factors.
  • pest control compositions are often made less effective or ineffective after application due to environmental factors. These environmental factors, including sunlight, oxidation, and rain, greatly increase cost to users because they require the user to make-up for the ever decreasing effectiveness of the pest control composition. Some users try to abate the damaging effects of the environmental factors by applying the product more frequently or by using a more concentrated dosage of the pest control agent. However, users could better control their costs due to environmental factors by using a pest control composition with better efficacy in the face of the environmental factors. As such, improved pest control compositions and methods of making such compositions are needed.
  • the present invention comprises a pest control composition, comprising: a) a first oil phase, wherein the first oil phase is selected from a group consisting of: vegetable oil, modified vegetable oil, and derivatives of vegetable oil; b) a second phase; and c) a pest control agent.
  • the present invention comprises a pest control composition, comprising: a) a first oil phase, wherein the first oil phase is selected from a group consisting of: vegetable oil, modified vegetable oil, and derivatives of vegetable oil; b) a second phase; c) a pest control agent; and d) an emulsifier.

For example, if a user with a conventional formulation and concentration needs to apply the pesticide three times a month to achieve the desired results, then that same user would be only be required to reapply the current pest control composition two or less times in that same time period and would achieve at least the same results.
