Definitions

  • the invention relates to the treatment of produce such as fresh and dried vegetables, flowers, ornamental crops, fruit and timber. More particularly the invention relates to a method and apparatus for fumigating pests and diseases from produce and products.
  • An object of the invention is therefore to provide an environmentally friendly method of treating produce against pests such as insect or grub infestation which method overcomes disadvantages inherent in existing methods and offers a useful alternative choice. Further objects and advantages of the invention will become apparent from the following description which is given by way of example only.
  • a method for killing most pests and diseases on produce such as live, dead or inert fruit, vegetables, flowers, ornamental crops and other products or material
  • the method including the step of: treating the products or material in a vacuum chamber with a gas fumigant and/or an oxygen depleting gas for a period sufficient to kill the pest(s) after the vacuum chamber has been evacuated to the required level.
  • the vacuum level may never achieve an absolute level where water boils off the surface of a water bearing produce or material.
  • the poisonous gas fumigant or oxygen depleting gas is only introduced under vacuum and is only vented when the required time of lethality has elapsed.
  • the poison gas fumigant or oxygen depleting gas can be introduced in a number of ways and in a number of forms.
  • any remaining gas is vented to the atmosphere, or captured and reused.
  • a number of further vacuum steps can be applied to the chamber and vented on the treated produce or material for the purpose of reducing chemical residues on the produce or material if required.
  • the reason for introducing the poison, gas fumigant or oxygen depleting agent (not methyl bromide) under vacuum is that when using a non-airdisplacing fumigant it is impossible to kill insects etc. in hard to reach areas, i.e. under tight leaves etc.
  • an apparatus adapted to carry out the method according to the invention.
  • Figure 1 shows a diagrammatic view of an apparatus adapted for use in killing most pests and diseases on products treated herein.
  • the produce or material to be treated is placed in a vacuum chamber 1 which can be of any construction and dimension.
  • a vacuum chamber 1 which can be of any construction and dimension.
  • vacuum pump 2 which can be connected via filter 3 to the chamber - 4 -
  • a gas fumigant and/or an oxygen depleting gas from source 4 is applied for a period sufficient to kill the pest(s) after the chamber has been closed/ sealed.
  • the vacuum level never achieves an absolute level where water boils off the surface of any water bearing material in the chamber.
  • the poisonous gas fumigant or oxygen depleting gas is only introduced under vacuum, and after the required treatment time is vented from the chamber 1 via vent 5. From vent 5 the gas is vented to atmosphere, or captured and reused.
  • the poison gas fumigant or oxygen depleting gas can be introduced in a number of ways and in a number of forms.
  • a number of further vacuum treatment stages can be applied and vented. This ensures the treated produce has few chemical residues on its surface.
  • the fumigant is applied under high pressure through a nozzle which causes a physical shearing effect that leads to pesticides that are not fumigants acting as though they are fumigants. This effect is achieved most commonly by dissolving the pesticide in carbon dioxide and applying the fumigant under pressure.
  • This technology was patented by BOC many years ago. The patent has now lapsed and Air Liquide now also uses the method. Generally most applications of this nature are insecticides. New research by BOC Gases New Zealand, Crop & Food Research and Taranaki Nuchem have led to patented technologies for dissolving more complex molecules in carbon dioxide and this leads to the ability to apply fungicides, antibiotics and sanitizers through this type of system. These new technologies may well have benefits for this application.
  • the pesticide may be able to be applied through a venturi system using carbon dioxide or another gas as the propellant.
  • Residue Profile data - milligrams per kilogram
  • the treatment chemicals' effectiveness can be altered in many ways such as temperature, amount and strength of chemicals and introduced length of time of treatment and type of product and the way the chemical is introduced into the vacuum chamber.
  • This method of fumigation does not affect either the phytotoxicity of the produce or its shelf life and usually has acceptable residue levels of the fumigant agent after fumigation.
  • Residue levels are directly related to the types of poisonous gas used, temperature, the length and strength of treatment and the type of material being treated.

Abstract

Procédé et dispositif permettant de tuer la plupart des parasites et de lutter contre les maladies attaquant les produits tels que fruits, légumes, fleurs, cultures ornementales et autres produits ou matériaux, vivants, morts ou inertes. Le procédé comprend les étapes suivantes: on traite les produits ou la matière dans une chambre à vide au moyen d'un fumigant gazeux et/ou d'un gaz entraînant un appauvrissement en oxygène, durant un temps suffisant pour tuer les parasites, après avoir vidé la chambre jusqu'au niveau désiré. Le niveau de vide peut ne jamais atteindre un niveau absolu quand l'eau, en bouillant, monte à la surface d'un produit ou d'une matière contenant de l'eau.
