Definitions

  • the present invention relates to novel insecticidal fumigants prepared using waxy suspension concentrates, to the processes for preparing such fumigants, and to their use for controlling harmful and / or troublesome insects.
  • Flammable insecticidal fumigants have long been known and commercially available. They are e.g. manufactured and distributed as "Mosquito Coil” (or simply “coils”). In these coils, various insecticides can be used, e.g. from the class of pyrethroids. However, some active ingredients used in conventional coils, however, have the disadvantage that they due Chem.-physic. Parameters tend to escape relatively quickly, so that their durability is limited. The volatility of some pyrethroids is attempted by the addition of evaporation inhibitors, e.g. Adipates or sebacates (e.g., EP 0 693 254), but with limited success. Furthermore, these coils are dried at lower temperatures to minimize such losses of active ingredient in the preparation.
