Abstract

Capacity of seeds of various varieties of coffee for sorption and desorption of phosphine following fumigation with 3 or 6 aluminium phosphide tablets (which release phosphine)/ton were determined. Coffee beans desorbed larger amounts of phosphine than corresponding samples of peaberry. At both dosages the amount of phosphine desorbed from both coffee beans and peaberry remained the same over a period of 2-4 days. The amount of phosphine desorbed decreased to <0.007 p.p.m. within 15 days and was negligible within 34-36 days.
