Species of the genus Penicillium are ubiquitous saprotrophs, spreading easily by conidia through the atmosphere. They appear most frequently in soil and on various organic matter. Penicillium olsonii had been found on seeds of various plants in the Philippines, Thailand and Indonesia. In our case, this fungus was found on the strips of rockwool in...

Species ofAesculusgenus are divided into five main sections according to their susceptibility and resistance to horse chestnut leaf miner using molecular markers.
Abstract
Some species of the genus Aesculus are yearly severely infested by horse chestnut leaf miner (Cameraria ohridella). The larvae mine the leaves and under appropriate...
Dried red pepper is one of the most commonly used spices in many parts of the world. In this study molecular biology methods were applied for detection of contamination in nine samples of paprika powder. Internal Transcribed Spacer (ITS) regions were selected for sequencing as they have a high variability between species and organisms and therefore...
Garlic is one of several important vegetable species grown in the Czech Republic. Ditylenchus dipsaci (Kuhn, 1857) (Tylenchida: Anguinidae), Aceria tulipae (Keifer, 1938) (Acari: Eriophyidae), Rhizoglyphus echinopus (Fumouze & Robin, 1868) (Acari: Acaridae) and R. robinii Claparede, 1869 (Acari: Acaridae), Suillia lurida (Meigen, 1830) (Diptera: He...
Pythium root rot of celery seedlings was found in greenhouses in South Moravia in the spring of 2015. Based on morphological characteristics and rDNA-ITS sequences, the causal organism was identified as Pythium mastophorum. The pot inoculation test demonstrated that P. mastophorum was pathogenic to celery and parsley. This is the first report of Py...
During 2011-2013, the frequency of occurrence and species spectrum of Fusarium fungi occurring on grains of five malting varieties of spring barley (Aksamit, Bojos, Malz, Radegast, and Kangoo) were monitored at two locations (Kroměříž and Žabčice, Czech Republic). The effect of three fungicide treatment variants on Fusarium species suppression was...
The aim of this work was to evaluate the growth dynamics and selected morphological characteristics of genetic sources of milk thistle (Silybum marianum L. Gaertn.) for the further development of the minimal set of descriptors. Milk thistle is grown in the Czech Republic for its achenes; however, the quality of achenes can be reduced by many factor...
Sweet basil (Ocimum basilicum L.) is an aromatic plant that is cultivated as a pot plant in greenhouses or in fields in the Czech Republic.

Leaf blight symptoms were observed on potted box plants (Buxus sempervirens cv. Suffruticosa and B. microphylla) in a nursery in South Moravia in August 2010. These symptoms were suggestive of box blight on Buxus spp. Characteristics of the visual symptoms, microscopic features, and identification of the isolates using DNA sequencing are described....
The coat protein (CP) gene DNA sequences of nine isolates of Hosta virus X (HVX) from different regions of the Czech Republic were determined and compared with sequences available in GenBank. The sequences were almost uniform, the pairwise nucleotide identities among the Czech HVX isolates were 99-100%. The respective range was 98-100% when sequenc...
Box ( Buxus spp.) is a traditional ornamental shrub widely planted in Europe. In the Czech Republic there have been no records of any important diseases of box so far. Dark brown spots were observed on the leaves of Buxus sempervirens …
A downy mildew disease was observed on leaves of Dianthus chinensis L. cv. Scarlet in Brno in June 2011. Characteristics of visual symptoms and microscopic features are described. The morphology of the fungus was typical of Peronospora dianthicola, conforming to the published description by FRANCIS (1983). P. dianthicola causing leaf spots on Diant...
Fungi of the Fusarium genus, the agent of ear rot in maize, not only causes decrease in yields but also negatively aff ects grain quality and, in relation to mycotoxins production, the health of humans and animals. This study focuses on determining the species range of Fusarium fungi in naturally infected stands of conventional hybrids and transgen...
Hostas ( Hosta spp.) are popular herbaceous perennial plants represented by over 7000 varieties, and widely cultivated due to their diversity in leaf shape and colour patterns, shade tolerance and pest resistance. In the Czech Republic,…
Fytopatogenni houby rodu Fusarium, způsobujici fuzariovou hnilobu klasů jecmene (běloklasost), jsou celosvětově významným zdrojem nebezpecných mykotoxinů ve sklizene produkci. Kromě tvorby mykotoxinů mohou negativně ovlivňovat výnos. Cilem prace bylo stanovit pomoci real-time PCR metody vliv odrůdy/linie, fungicidniho osetřeni a lokality na přiroze...
A possibility of using spectral methods for determining a nutritional status and detecting pathogens in apple-tree cvs. 'Jonagold' and 'Idared' was verified in an orchard and pot experiments in 2007- 2010. Treatments differed in the fertilizer or fungicide dose. Leaf samples were collected from the experimental variants to determine nitrogen conten...

In November 2009 the gall midge species Horidiplosis ficifolii Harris 2003 was detected in the Czech Republic on leaves of an ornamental fig Ficus microcarpa. The insect is native to South East Asia, where it lives on the genus Ficus. No information is currently available on the prevalence of the pest in the countries of its origin. Imported Ficus...
In the years 2005-2007 in a collection of 527 cultivars of tall large-flowered irises (Iris x barbata group Elatior) in the Botanical Garden and Arboretum of MZLU in Brno the fungus Botrytis convolute infested the plants. Within three years, as a consequence of the infestation, some cultivars showed symptoms of poor growth, in isolated cases the pl...
In the years 2005-2007 in a collection of Iris x barbota irises in the Botanical Garden and Arboretum of MZLU in Brno a disease spread appearing in symptoms of poor budding and growth of the irises, or rotting and dying off of the rhizomes. As the causal agent we identified the fungus Botrytis convoluta. In the present study we describe the isolate...
In the spring of 2008, leaf spot was observed on Rhododendron hippophaeoides and Rhododendron obtusum; the causal agent was identified as the rust Chrysomyxa rhododendri. The rust occurs primarily in mountain regions and in the Czech Republic was first observed 105 years ago. In the present study we describe pathogen morphology and symptoms on the...
