Fungicide residues in pears and apples after post harvest treatments by drencher.

Aim of this trial was to verify the residues of two fungicides, already authorised for the use in field (the admitted maximum limit of residues have been fixed), after post harvest treatments on pears and apples for defence against main post harvest rots. The use of formulation in post harvest must consider also the technique of product application. In fact there are different systems to carry out the treatments for the protection of the commodities during cold storage. In this trial two formulations of pyrimethanil and imazalil were applied by drencher on pome fruit.
