28-minute video and poster on phosphine fumigation techniques
Grain fumigation faces two important challenges: how to overcome insect resistance to phosphine, which is increasing because of poor fumigation techniques; and the need to find a replacement for the alternative fumigant, methyl bromide, known to deplete stratospheric ozone, which is being gradually phased out. Consequently, it is important to slow or halt the development of phosphine resistance and to preserve the efficacy of what will become the principal grain fumigant. Training in good phosphine fumigation techniques is essential to achieve this. The Natural Resources Institute (NRI) has produced a video and poster on this subject. The first part of the 28-minute video deals with the main requirements for good fumigation, irrespective of whether the treatment is of a silo, freight container, bag stack or whatever. The second part demonstrates how to undertake fumigation of a bag stack under gas-tight sheets. This was chosen for detailed explanation since it is the most common method used in developing countries. Both the video and poster are designed as aids in support of training courses in pest control to encourage safe and effective fumigation techniques. Copies are available from NRI, free of charge to countries who are recipients of British Aid; otherwise they cost £20.
