Penicillium (Penicillium spp.) and soot (Aspergillus niger) are two important fungal diseases in hyacinths that cause infections, especially during storage. Two natural antagonists, selected through research in part 1 of this project, were applied to bulbs in storage to assess their effectiveness in controlling these diseases. The antagonists were applied to the bulbs by dipping, misting and foaming. Although some interesting effects were observed, none of the antagonists had a significant effect on pathogen control. Clearly, the process of applying the antagonists to the bulbs helps in spreading the spores and increasing disease incidence compared to bulbs that were not dipped, sprayed or covered with foam. We cannot recommend the use of these antagonists for prevention of Penicillium or soot. However, with the removal of the current standard of chemical agents, they could play a role in an integrated management program in the future.
