Beginning in 2006, a survey of two related Phytophthora species, P. multivora and P. plurivora, was performed in the Czech Republic. Both pathogens were distributed throughout a broad range of environments including forest and riparian stands and probably became naturalised in the country. The two species differed in their frequency and elevational distribution. P. multivora was less frequent, but commonly occurred in the lowest regions such as Central Bohemia and South Moravia, i.e. areas which generally exhibit a high level of invasion. This species was isolated primarily from Quercus robur and found to...
Leaf spot and dieback of Buxus caused by Cylindrocladium buxicola Original Paper

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 causal agent was isolated and identified as Cylindrocladium buxicola Henricot by means of morphological, cultural, and molecular characters. The effect of five commercial fungicides on C. buxicola in vitro was studied. The most effective fungicides...
Pathogenicity of Beauveria bassiana to fall webworm (Hyphantria cunea) (Lepidoptera: Arctiidae) on different host plantsOriginal Paper

A study on the compatibility of the entomopathogenic fungus Beauveria bassiana with two medicinal plants, Artemisia annua (0.5%) and Lavandula stoechas (0.6%), was conducted against fall webworm, Hyphantria cunea, in the presence of three host plants including plane tree (Platanus orientalis), boxelder (Acer negundo), and mulberry (Morus alba). The highest concentration of B. bassiana yielded the highest H. cunea mortality in all three host plants. The combination of B. bassiana and plant extracts caused the highest H. cunea mortality in all host plants....
Species of the genus Meligethes occurring in oil-seed crop fields in the Czech RepublicOriginal Paper

Identification of Meligethes species and their frequencies in adult samples collected at different localities in Central and South Moravia (Czech Republic, 2009-2011) was based on comparisons of morphometric and colour characters and on differences in male and female genitalia. M. aeneus, M. viridescens, M. subaeneus, M. atratus, and M. coracinus were recorded throughout the observation period, while M. nigrescens was recorded just in 2009 and 2011, M. carinulatus and M. maurus in 2010 and 2011. M. aeneus was the most frequent species of all compared samples (2009-2011)....
Migration flight of carrot psyllid (Trioza apicalis) at various latitudes is independent of local phenologyOriginal Paper

A particularly advantageous method of monitoring the flight and calculating the median was used. An example is given in order to understand better the calculation. The medians show that the timing is similar at different latitudes despite local phenological differences. The difference in median flight times between Finland and the Czech Republic was five days on average, but phenological differences are about a month, shown by a comparison of temperatures, the monitoring of buds on spruce, and by the stage of the carrot plants. During the attack by T. apicalis the carrot plants are younger towards north what is unusual in Psyllidae. In extreme...
Fatal germination in barnyardgrass (Echinochloa crus-galli)Original Paper

Seeds of weeds buried by tillage may germinate at depths from which seedlings cannot establish. In barnyardgrass (Echinochloa crus-galli) we investigated how fatal germination was influenced by the depth and time of seed burial. The proportion of germinated seeds decreased with burial depth to 0-20% at ≥ 0.1 m depth which is fatal for seedling establishment. The percentage of fatal germination was greater for the seeds buried during the spring season than during autumn. Germination was influenced by seed pre-treatment, after ripening or stratification. Spring ploughing of non-dormant seeds below 0.1 m depth induces fatal germination, decreasing...
