several challenges, including the unwitting contamination of soils and fruits with the heavy metal cadmium (Cd) ( DAFF, 2011 ; Hill and Fraser, 2011 ). A zinc sulfate fertilizer that was imported from China in 2004 resulted in a Cd concentration higher

Three types of soil were mixed with water containing DPA (2000 mg·liter-1) and benomyl (300 mg·liter-1) at 1% to 5% (w/w). `Rome' apples (Malus domestica Borkh.) were dipped in the mixtures over 8 days. The efficiency of DPA as a scald inhibitor was not consistently affected by soil type, soil concentration, or age of mixture. Chemical names used: methyl[1-[(butylamino)carbonyl]-1 H-benzimidazol-2-yl]carbamate (benomyl); diphenldyamine (DPA).
