Hyacinth stalks treated after harvest with Basilit Pn, Impra and Basiment 300 were stain-free for two months while control or untreated stalks and those treated with Borax were attacked by staining fungi during the first week of test. Grayish to blackish spots or streaks were found near the basal area of the stalks while thin, white mycelia were found on the tips or apices. Species of Penicillium, Curvularia, Alternaria, Cladosporium and Aspergillus were isolated from the stained samples. The same results were obtained from stalks treated after weaving into straps. Fungal signs were found on the overlapped surfaces. Mycelial characteristics of each species of staining fungi used in the study varied among agar media used. On the other hand, radial gowth did not vary significantly among media, except for Penicillium sp. 2.
