Methods of distributing phosphine in bulk grain

Summary

The use of phosphine as a means of treating infestation of bulk grain is on the increase, and significant changes in traditional applicaion methodology are being developed. This review seeks to collate the information currently available on the use of phosphine in grain storage practice. Although much has been published on the results of treatments with this fumigant, usually the operations described only relate to specific aspects of individual fumigation situations. There is an emerging need to bring together information on the more recent advances and on older methods. This at present exists in disparate and scattered accounts in trade and scientific publications and in unpublished reports.

Literature searches using computerised databases have been carried out to cover the period from 1970 to 1992 to supplement the research database and information available to the fumigation research team at the Central Science Laboratory (CSL), Slough.
