An optimised method for determining the presence of the seedborne fungus Alternaria alternata, a potential producer of harmful mycotoxins, on material of carrot (Daucus carota)

The method is based on a blotter test and involves examination of the fungal morphology after 7 days of incubation. For testing seeds a deep-freeze step to prevent germination is necessary. The diagnosis involves microscopic observation of the fungus sporulation on incubated carrot seeds, seedlings and roots. The test is completed within 7 days which is advantageous in terms of work planning in a laboratory. Based on the results from a ring test with 5 laboratories and 4 levels of seed contamination, it was concluded that the deep-freezing-blotter-test provides reliable information on the seed contamination with Alternaria alternata.
