Abstract
A process and an apparatus for forming aerosols of pesticidal chemicals, said process comprising vaporizing water in a steam generator fitted with a heater, heating the resultant steam to 110.degree.-800.degree. C in a superheating means, passing the superheated steam from the superheating means, while controlling its temperature, to an evaporator containing the pesticidal chemicals and connected to the steam generator through superheater thereby to effect the heating, evaporation and entrainment of the chemicals with steam, releasing the resulting entrained vapor in the air to form aerosols of the pesticidal chemicals. The aerosols are used to control indoor or outdoor fungi, bacteria, viruses, and insects.
Claims10
A process for applying an insecticidal or fungicidal chemical to living plants in an enclosed area which comprises:
- 1. passing superheated steam having a temperature of from 110.degree. C. - 800.degree. C., through a vaporizable solid state insecticidal or fungicidal chemical thereby to evaporate said chemical, said superheated steam being the means employed to heat said chemical;
- 2. subsequently rapidly releasing the resulting entrained vapor into the air to rapidly cool said vapor and to form an aerosol of the insecticidal or fungicidal chemical in the vicinity of said living plants, and
- 3. then contacting said living plants with an insecticial or fungicidal amount of said chemical in the form of said aerosol.
