ABSTRACT :
During 1988 and 1989, the surfaces of wooden bins used in the Hood River Valley, Oregon, USA, were sampled prior to pome fruit harvest to determine whether decay fungi were present. Alternaria spp., Cladosporium spp., Mucor piriformis and Penicillium spp. were found on 73, 25, 21 and 77%, respectively, of the bins in 1988 and 69, 46, 19 and 83%, respectively, in 1989. Several methods of disinfestation were tested for reduction of A. alternata and P. expansum on pieces of wood and plastic used in bins. Steam was the most effective treatment. Benomyl, iprodione and captan were generally ineffective, although benomyl + captan was effective against P. expansum spores on wood. Chlorine compounds, SOPP (sodium orthophenylphenate) and quaternary ammonias were effective disinfestants but were occasionally less effective than steam. Most treatments showed similar efficacy on plastic and wood.
