Container fumigation

Rentokil offers fumigation of containers with Magnesium Phosphide Plates or Phostoxin tablets ensuring the right dosage is used depending on the preliminary weevil infestation found on the beetle traps installed prior to fumigation.

We do the following operations:

  • Ensure that gas sample lines to one bale centre in a container and to the bale exterior area are placed.
  • Ensure that adequate temperature and gas readings at right times are taken. Temperature readings are undertaken prior to fumigation to verify the dosage.
  • Ensure that gas concentration readings are taken. This is done with electronic detectors while test readings are done by manually operated detector tubes.
  • Ensure that electronic readings are taken by versatile detectors that contain an internal sample pump and a flexible sampling wand to allow efficient monitoring. A large character display ensures that measured values are easily visible, and a back-light for the display insures readability in low or no light conditions.
  • Ensure that all data is reliable. Computer interface is a standard feature of the electronic gas detector. An RS-232 output allows stored readings data to be downloaded to a computer through an interface cable supplied with the unit. This facilitates simple data transfer of information for record purposes and for inclusion on fumigation certificates.
  • Ensure that aeration is done with warning signs being placed on all four sides of each container. Personnel are not allowed in areas where concentration exceeds 0.3ppm.
  • Ensure disposal of Plates is done by placing in a wire basket with a lid before immersion in water to prevent them from floating.
  • Ensure that beetle traps are placed in each container after fumigation but prior to shipment. These traps have suitable identification codes, date of treatment and pertinent container number;
  • Ensure that pertinent paperwork is provided. This includes a fumigation certificate outlining the volume treated, quantity of cartons, dosage, date fumigant is placed, date when aeration is done, phosphine concentration readings and ambient temperature readings.
