Özet

Methyl bromide (MeBr), a fumigant widely used to control storage pests in dried fruit and nut industry, is banned for use because of ozone layer depletion according to the Montreal Protocol. Dried fig industry is the most affected from MeBr ban due to prevalence of storage pests namely fig moth (Ephestia cautella). Magnesium phosphide was tested for exposure times of 3 and 5 days at 0.70 g.m(-3) phosphine (PH(3)) and 1.33 g.m(-3) PH(3) of dried fig in gas-tight storage units containing 15 ton of dried figs in boxes of 25-30 kg to control two major pests of dried figs, fig moth and fig mite (Carpoglmhus lactis). The control fruits were fumigated with MeBr at 40 g.m(-3) for 24 h. The results proved that the tested concentrations and exposure periods to PH3 provided that 100% mortality of the test species. After exposure to PH(3) or MeBr, fruit quality was preserved under ambient storage conditions for 4 months. The lower dosage of PH(3) does not cause any adverse effect on fruit quality.
