Abstract

Cashew nuts and hard brown Punjab wheat, free of infestation and not previously fumigated with PH3, were used in the studies. Samples of the nuts and wheat were placed in flasks and fumigated for 1 or 2 wk with Celphos pellets at 18 mg/kg (i.e. 6 AlP tablets/ton or 6 g PH3/ton) at room temp. (29-31 degree C). After fumigation, the samples were stored for less than or equal 15 days and examined at intervals for PH3 and P residues and for PH3 desorption. Results are detailed in graphs and tables. On the basis of the results obtained, it is concluded that bound PH3 residues do not occur in wheat and that in cashew nuts PH3 does not form bound residues but is held in the dissolved form in the lipid fraction. Oxidation of the PH3 residues was more prevalent in wheat than in cashew nuts, as indicated by the higher P levels in wheat.
