ABSTRACT
The present paper determined the occurrence and harmfulness of fungi, especially Septoria carvi, towards different cultivars of caraway Carum carvi L. in the climatic conditions of the Lublin region. The studies were conducted in the years 2001-2004 on the plots sown with schizocarps of the cultivars Arterner, Niederdeutscher, Record and Konczewicki. The percentage of plants with disease symptoms on the aboveground parts and the percentage of leaves and umbels with the symptoms of septoriosis were determined in the second years of caraway cultivation. The fungi were identified on the basis of etiological symptoms visible on the infected plant parts and on the basis of the mycological analysis by the method of artificial cultures. The major pathogen to caraway in the examined conditions was fungus Septoria carvi, causing necrosis of the leaves, leaf petioles, stems, umbels and schizocarps. In the conditions which were favourable to the development of S. carvi, all the tested cultivars, and especially Niederdeutscher, were highly susceptible to this pathogen. A complex of other fungi species, including Botrytis cinerea, Rhizoctonia solani, Colletotrichum gleosporioides and toxin-forming species from the genera of Fusarium and Altenaria were isolated from the aboveground parts of caraway every year. Sclerotinia sclerotiorum occurred on the roots and the stem base of the examined cultivars in 2004.
Key words: caraway, fungi, diseases.
