Description
| - The spectrum of diseases and their harmfulness to caraway has changed within the past few years. The importance of Mycocentrospora acerina, recently regarded as the most serious pathogen, has decreased while the severity of other fungi, such as Erysiphe heraclei or Ascochyta carvi, has increased. This work was undertaken to identify and determine the incidence of fungi which contaminate the seeds and to evaluate the effect of fungicidal treatment. Direct microscopic evaluation confirmed that Alternaria alternata and Cladosporium cladosporiodes were the most common fungi occurring on caraway seeds. Cladosporium herbarum, Fusarium avenaceum, F. culmorum, F. equiseti, Fusarium sp., Epicoccum nigrum, Trichothecium roseum and Aureobasidium sp. were not so frequent. In field trials during 2005 and 2006, fungicide application at flowering of the crop affected mainly the pathogenic fungi Ascochyta carvi and Septoria carvi, but not the saprophytic fungi A. alternata or Cladosporium sp.

- V posledních letech se spektrum chorob a poškození kmínu kořenného změnilo. Důležitost patogena Mycocentrospora acerina, který byl do nedávna považován za nejvážnějšího původce choroby na kmínu, se snižuje, zatímco vzrůstá význam patogenů dalších, jako Erysiphe heraclei nebo Ascochyta carvi. Cíle práce bylo identifikovat a determinovat druhy hub kontaminujících semena kmínu a stanovit vhodnou fungicidní ochranu. Přímým mikroskopickým určením bylo zjištěno, že nejvíce se na semenech kmínu vyskytují Alternaria alternata and Cladosporium cladosporiodes. Cladosporium herbarum, Fusarium avenaceum, F. culmorum, F. equiseti, Fusarium sp., Epicoccum nigrum, Trichothecium roseum and Aureobasidium sp. se nevyskytovaly často. V roce 2005 a 2006 v polních pokusech ovlivnila aplikace fungicidů v době kvetení zejména patogenní houby jako Ascochyta carvi a Septoria carvi, ale neovlivnila saprofyty, A. alternata nebo Cladosporium sp. Ve srovnání s kontrolou vzrostl výnos nažek v roce 2005 pouze u aplikace prothioc (cs)
