MÜLLER J. (2010): Beitrag zur mykofloristischen Erforschung der Rost-, Brand und Falschen Mehltaupilze auf dem Králický Sněžník (Glatzer Schneeberg) und seiner Umgebung (Tschechische Republik).   [Králický Sněžník, Peronosporomycetes, Pucciniomycetes, Ustilaginomycetes, Microbotryomycetes]  Czech Mycology 62(1): 87-101   (published: 15th February, 2011)
  abstract   Between 1889 and 2001 a total of 17 species of downy mildews (Peronosporomycetes), 6 species of smut fungi (Ustilaginomycetes), 79 species (respectively varieties) of rust fungi (Pucciniomycetes), and 2 species of Microbotryomycetes were found in the Králický Sněžník and its surroundings. The investigated territory is delimited, a brief history of the research into these micromycetes is given, and a survey of 10 species of downy mildews, 2 species of smuts and 55 species of rusts found by the author is given. The results of the research were compared with historical records. The author found 34 species new to the territory concerned. On the other hand, he has not been able to verify the occurrence of 37 species recorded by previous mycologists, especially on the summit of Králický Sněžník.

DIETRICH W. (2005): Die Rost-, Brand- und Falschen Mehltaupilze des tschechischen Teiles des Erzgebirges (Krušné hory): erster Nachtrag.   [Peronosporales, Urediniomycetes, Ustilaginomycetes, Czech Republic, Krušné hory]  Czech Mycology 57(3-4): 257-273   (published: 10th February, 2006)
  abstract   In the years 2000-2004 several species of Urediniomycetes, Ustilaginomycetes and Peronosporales were found that are new to the Czech part of the Krušné hory Mts. A total of 57 taxa had not been pub­lished before. In this region 227species, subspecies and varieties are known to date. The distribution of selected species is shortly discussed and compared with the literature. Characteristic species of the more arid and warmer area of the south-east as well as the highest altitudes of the Krušné hory Mts. are enumerated. New hosts in the Czech Republic are the following: Calthapalustris subsp.procumbens for Puccinia calthae, Chaerophyllumhirsutum for Puccinia bistortae, Pinus x pseudopumilio for Coleosporium senecionis, Poa chaixii for Puccinia graminis and Phyteuma nigrum for Uromyces phyteumatum. The western and eastern parts of the Krušné hory Mts. have so far been investigated only to a minor extent.

  abstract   Relative air humidity significantly affects the formation of sporangia and the release of zoospores in Peronoplasmopara humuli. The most favorable humidity is 90–100%, with viability of sporangia and zoospores decreasing at lower humidity. The study details germination and sporulation behavior under different humidity levels.

  abstract   Laboratory culture of Peronoplasmopara humuli enabled detailed study of temperature effects on its lifecycle. The optimal range for zoospore release was 19–25 °C. Infection occurred between 1–29 °C, with 21–25 °C as optimal for a 3-day incubation period. Very low or high temperatures did not reduce the pathogen’s infective ability under optimal conditions.

PARVEEN S., WANI A.H., BHAT M.Y., KOKA J.A. (2016): Biological control of postharvest fungal rots of rosaceous fruits using microbial antagonists and plant extracts - a review.   [biological control, postharvest diseases, microbial pesticides, rosaceous fruits]  Czech Mycology 68(1): 41-66   (published: 1st February, 2016)
  abstract   This article aims to give a comprehensive review on the use of microbial antagonists (fungi and bacteria), botanicals and compost extracts as biocontrol agents against different pathogenic fungi causing postharvest fungal rots in rosaceous fruits which shows that they can play an important role in the biomanagement of fungi causing rot diseases. Plant extracts reported in the literature against pathogenic fungi indicate that they can act as a good biological resource for producing safe biofungicides. However most of the work has been done under experimental conditions rather than field conditions. There is still a need for research to develop suitable formulations of biofungicides from these microbial biocontrol agents and plant extracts. The review reveals that extensive ecological research is also required in order to achieve optimum utilisation of biological resources to manage various postharvest diseases of fruits.

KUTHAN J. (1992): Mycoflora of large-scale greenhouse plantation of salad cucumbers.  Česká Mykologie 46(1-2): 1-32   (published: 1st April, 1993)
  abstract   In the course of the years 1988–1991 the author used to visit large-scale greenhouses at Paskov near Ostrava (NE Moravia, Czechoslovakia) and surveyed not only the abundant growth of particularly higher fungi there, but in 1989 he tried to summarize the weight of biomass of the most frequent species. The results of the observation of biomass, frequency, abundance and phenology are presented in the tables. Altogether 95 macrofungi taxons, 1 species of Hyphomycetes and 1 species of Myxomycetes were recorded and they are given in the systematic summary, potentially with comments.

HORÁKOVÁ J., SKALICKÝ V. (1989): Contribution to the ecology of Peronospora violacea Berk.  Česká Mykologie 43(1): 13-29   (published: 6th February, 1989)
  abstract   Peronospora violacea Berk. is an obligate floricolous Peronospora. All floricolous parasitic fungi of the family Peronosporaceae belong to the genus Peronospora Corda, probably to only one evolutional complex; of the foliicolous parasitic species, Peronospora destructor (Berk.) Casp. is their closest relative. It is impossible to distinguish individual microspecies within P. violacea Berk. on the basis of host plants; three new host species were found. The systemic infection of the Knautia species by both indirect and direct methods (replanting, histological proof of mycelium) was demonstrated. The data on oospores were corrected and completed. Basing on the revision of all materials preserved in the Czechoslovak public herbarium collections, a map of distribution of this species in Czechoslovakia was compiled and evaluated. A special chapter is devoted to the problems of nomenclature.

  abstract   Light with an intensity of 1000 to 5000 lux inhibits the release of zoospores and the formation of zoosporangia of hop downy mildew (Peronoplasmopara humuli Miy. et Tak.). Zoosporangia release zoospores in water suspension both in light and darkness already after one hour. With increasing light intensity, however, the percentage of zoosporangia releasing zoospores decreases: after 6 hours 95% release zoospores in darkness and 72–84% in light. Light affects more sharply the onset of zoosporangia formation and the density of the mildew coating. In darkness the first zoosporangia form after 4 hours and a continuous dense coating after 12 hours. In light, depending on intensity, the first individual fruiting bodies and zoosporangia form after 6–22 hours, and their number remains nearly unchanged even after 30 hours of exposure. The inhibitory effect of light is only temporary, as the pathogen resumes forming dense, infective zoosporangia after 10–20 hours back in darkness under optimal conditions.
