In June 2008, premature yellowing and wilting of foliage were observed in a 32 ha commercial garlic (cv. Arno) within the biggest Allium-producing region of Hungary, 200 km southeast of Budapest. The underground parts of affected plants were covered with a white mycelial mat producing black spherical sclerotia with diameter up to 0.5 mm. Roots and bulbs were rotten and the rot had spread onto the lower part of leaves. Similar symptoms were recorded in the adjacent onion field (cv. Glacier). Finally, the infected plants died. Bases on morphological characteristics, sequence analysis of rDNA ITS and pathogenicity test, the causal agent was identified as Sclerotium cepivorum [Stromatinia cepivora]. This is thought to be the first report proving the occurrence of S. cepivorum in this country.
