    Uittreksel

    Storage diseases of pome fruits are caused by different fungal species. Disease
    management to control storage diseases includes several treatments with different fungicides in the weeks prior to harvest. However, residues on fruits becomes more and more a public and governmental concern. In order to reduce the chemical residue on fruits to a minimum, more research is done on alternative disease management. In this respect, in 2013, a project on ‘Nebulisation of biological control organisms in cold storage rooms to
    control storage diseases’, which is funded by the Agency for Innovation by Science and Technology, has started at the pcfruit institute in collaboration with ILVO and the University of Leuven. Here the efficacy of several biological control organisms (BCOs), applied through specific atomization in the cold room, against storage diseases was examined.
    Besides that, also the influence of additives on the efficiency of BCOs in their control of storage diseases was investigated. Two groups of fungal pathogens causing storage diseases were monitored. The first group comprises the latent fruit rot pathogens like Neofabraea spp., which infect the fruits already in the orchards through natural openings like lenticels. For this type of pathogens symptom expression is delayed till after a long storage period. The second group are the wound pathogens (Botrytis cinerea, Monilinia spp., Penicillium spp.) that penetrate the fruits through accidental wounds, for example during picking. However, not only the efficacy of the BCOs is important but also the homogeneous distribution of the compounds in the cold storage room. The first results of this project will be presented.
