Wheat (Triticum aestivum, L.) grass family Poaceae (Gramineae) is the most important strategic cereal crop for the majority of the world population. Storage fungi especially Fusarium species such as Fusarium graminierum and F. verticilloides infect grains before and after harvest and can grow on them during storage. These fungi produce mycotoxins that threaten human and animal health and cause severe illness or even death. The presence of insects augments the heat spots, the inoculum potential of storing fungi and the seed contamination of high amounts of mycotoxins, leading to high seed yield losses value during storage. The fumigation with aluminium phosphide tablets was usually used for controlling and killing these insects during storage. Unfortunately, this chemical was not safe for humans. This study aims to investigate the effect of aluminium phosphide against F.verticilloides and F.graminearum and their produced mycotoxins compared to sorbic acid as a safe and useful alternative.
