Rice fumigation is a method of pest control that uses a phosphine (PH3) or with low oxygen, treatment to exterminate pests in an enclosed space.
The whole fumigation procedures take about ten days. After the fumigation is complete, the fumigator will have to aerate the fumigant from the structure and monitors the air for re-entering the area.
Global rice exporters will use Methyl Bromide or Phosphine.
Methyl Bromide fumigation was a globally effective disinfestation treatment for many years. However, it recently has been identified as a significant ozone-depleting chemical and now is no longer a fumigant other than for quarantine and pre-shipment applications under the Montreal Protocol.
The current fumigation uses Phosphine, a cost-effective method of eliminating Stored Product Insect Pests (SPIs); such as weevils, beetles, moths, and mites in commodities.
