Phosphine desorption from coffee seeds fumigated with aluminium phosphide preparations
Coffee beans (Arabica, parchment) fumigated at two dosages of 3 and 6 aluminium phosphide (AIP) tablets/ton, desorb larger amounts of phosphine (PH3) than the corresponding samples of peaberry. On certain days larger amounts of PH3 are desorbed than the preceding day due to stratification of PH3 in sample bulk in both the types of coffee seeds. At both the dosages the amount of PH3 desorbed from both the types remained the same over a period of 2 to 4 days. Irrespective of the dosages, in both the types, the amount of PH3 desorbed decreases to a value less than 0.007 ppm within 15 days, and to a zero value within 34-36 days
