Imazalil residue loading and green mould control on citrus fruit as affected by formulation, solution pH and exposure time in aqueous dip treatments

► Solution pH affected imazalil residue loading on citrus fruit with imazalil sulphate formulation. ► Increasing pH increased residue loading in imazalil sulphate solution. ► Benchmark residue levels for sensitive and resistant Penicillium digitatum isolates were estimated.
