Carrot is among the most important vegetable crops because of its composition and vitamin content. The fungi belonging to genus Alternaria, especially A. dauci (Kühn) Groves et Skolk, causal agent of leaf spot and blight of carrots, and A. radicina Meier, Drechsler et Eddy, the agent of black root rot, can jeopardize the entire production of carrots. Both types can be found in a high percentage of seeds, carrots, parsley and celery. The method of detection fi lter paper (blotter method) and the method of isolation on malt agar were recommended by ISTA Rules. The presence of A. dauci (causal agent of leaf spot and blight of carrots) and A. radicina was performed on 12 samples of potentially infected carrot seeds originating from France, as part of laboratory ring tests. The presence of A. dauci and A. radicina using the filter paper method in 12 tested samples ranged from 0% to 21% and from 1% to 30% respectively. On MA medium the respective percentages ranged from 0% to 23% and from 1% to 31%.
