These are pesticides that utilise gases that they liberate to control pests. A number of fumigants are available in canisters of different pack sizes for convenience. The gas phosphin is used for control storage pests in sheds and silos and other confined spaces where storage pests can wreck havoc for example in maize, tobacco, wheat and others. This is available in tablets form and mainly Aluminium phosphide and Magnesium phosphide are available.

The use of fumigants requires expertise and experience as these are very dangerous chemicals which if administered or used incorrectly results in unnecessary loss of life. Please contact a ZFC representative for advice when unsure of correct usage.
