The evaluation of healthiness of infected mountain pine’s needles was conducted for three years (2011–2013) at few experimental places: Równia pod Śnieżką, Spalona Strażnica, Kocioł Małego Stawu, Kocioł Wielkiego Stawu, Łabski Szczyt and Szrenica. Needles with symptoms of brown spot needle blight were found in subalpine zone of Karkonosze Mts. The field research observations revealed that the greatest severity of symptoms of brown spot needle blight on needles occurred in July. In the first year of the study (2011) disease symptoms were recorded at a level of 5–10% of infected needles at each studied site. In the second year of the study the least number of plants with spotted brown needles (5% of infected needles) was recorded at Równia pod Śnieżką, Kocioł Małego Stawu, Łabski Szczyt and Szrenica while the plants in the region Kocioł Wielkiego Stawu were the most infected, up to 15%. In 2013 situation changed and the highest number of infected plants was at Równia pod Śnieżką (15%).

Seeds of Abutilon theophrasti grown in Poland were colonized at least by 11 species of fungi. Alternaria alternata was the most common species. Its frequency in the fungal community amounted to 62%. Epicoccum nigrum and Aspergillus spp. were also common fungi on/in seeds, occurring usually with local or temporal peaks. Other fungi, including Fusarium, Botrytis cinerea, Sclerotinia sclerotiorium and Trichothecium roseum occurred sporadically.

The studies were carried out in the period of 2005–2007. The tillage systems were taken into consideration including the following experimental factors: I factor – cultivation system – a) simplified tillage without ploughing, b) conventional tillage with ploughing, c) direct sowing; II factor – stubble height – a) low stubble, b) high stubble; III – factor – winter wheat varieties: Mewa, Rapsodia and Legenda. Winter oilseed rape was a previous crop to winter wheat during the whole experimental period. At the milk and wax maturity of grains the observations of winter wheat plants were performed on the infection by complex of stem base diseases. The mutual relations among the experimental factors, i.e. the number of diseased stems, height of stubble, tillage systems and winter wheat cultivars were subjected to the log-linear analysis. It was stated no interaction between stubble height and the intensity of stem base diseases. Direct sowing caused a slightly higher intensity of the stem base diseases. The variety Rapsodia was more susceptible to stem base diseases, as compared to the other varieties.

The studies were aimed at determining of the relation between the occurrence of the complex of stem-base diseases on cultivars of winter wheat, depending on farming systems and weather conditions. Three experimental factors, were analysed, Factor 1 (farming systems): (a) simplified farming, (b) conventional plowing, (c) direct sowing, Factor 2 (stubble length): (a) short (10 cm) or (b) long (40 cm). Factor 3: three cultivars of winter wheat. In particular, wheat diseases caused by pathogenic fungi were taken into consideration. The plants with disease symptoms on stem-base were counted and picked up from the 100 plants sampled diagonally through the experimental plots. Basing on the bi-plot curve, various levels of susceptibility of wheat cultivars on the complex of diseases of stem-base were stated in dependence on weather conditions prevailed in a given year and to on the farming systems used. The only exception was the reference cultivation, where the effect of changing stubble length on intensity of the occurrence of wheat diseases (Fusarium ssp.) showed to be insignificant. In the conditions of plow less farming and short stubble, the cultivar Mewa revealed increased susceptibility to the pathogenic fungi.

Fungi occurring as saprophytes or parasites on a variety of substrata. Concentrations of airborne fungi depend on several factors f.ex.: weather conditions, vegetation, height above the sea level and human activities. The experiment was conducted in 2011–2012. The occurence of plant pathogenic fungi was found in the air of subalpine zone of Karkonosze National Park and in Izerskie Mountains. Air samples were taken from 3 locations on the Karkonosze Mts and one from Izerskie Mts. To examine the air Air Ideal 3P sampler and acidified PDA (Potato Dextrose Agar) medium were used. The highest numbers of CFU/m3 air (Colony Forming Unit of 1 m3 air) of fungus were isolated from the Hala Izerska in Izerskie Mts on April 2011, and Szrenica top in Karkonosze Mts on September 2011. Cladosporium cladosporioides was the most abundant species at all locations (up to 30%) followed by Alternaria alternata (16–20%), Fusarium spp. (up to 10%) and Sclerotinia sclerotiorium (up to 6%). The genus Cladosporium is one of the most abundant airborne fungi. Also A. alternata shows a similar pattern in response, like another fungi species Fusarium or S. sclerotiorium.

The study was aimed at log‐linear analysis and determining the intensity occurrence of Epicoccum nigrum on wheat grain depending on cultivar factors, cultivation system, stubble height and weather conditions. Three factors were taken into consideration: I – tillage systems, i.e. simplified plough‐free, conventional and direct sowing; II – low stubble (10 cm) and high stubble (40 cm); III – winter wheat cultivars. The analysis of correspondence revealed that the intensity of grain colonization of winter wheat cultivars by E. nigrum was directly related to a soil cultivation system and stubble height. In the case of low stubble, the intensity of occurrence of E. nigrum was significantly higher. The cultivar Rapsodia showed to be highly susceptible to the fungus colonization, while the cultivars Mewa and Legenda were more resistant. Irrespectively of the stubble height the highest grain colonization was recorded on wheat cultivated with the conventional system. Nevertheless, a significantly smaller number of E. nigrum isolates was found on wheat grain the zero experimental plots.

W doświadczeniu wazonowym badano wpływ podwojonej dawki nawozów azotowych i przedplonu (pszenżyto jare, jęczmień jary, owies oraz mieszanki tych gatunków) na porażenie pszenżyta jarego przez choroby podstawy źdźbła oraz jego plonowanie. Porażenie podstawy źdźbła pszenżyta przez choroby było niewielkie, nie mniej jednak zależało od obu czynników doświadczenia. Uprawa pszenżyta jarego po sobie powodowała wzrost zainfekowania podstawy źdźbła i liczebności wyizolowanych grzybów patogenicznych, ale nie wpłynęła na obniżkę plonowania pszenżyta. Pszenżyto uprawiane po mieszankach, a szczególnie po owsie, odznaczało się istotnie mniejszym indeksem porażenia, ale także niżej plonowało. Ryzyko infekcji przez choroby podstawy źdźbła można ograniczyć poprzez podwojenie dawki nawozów azotowych.

In the years 2001 – 2003, there were analyzed relations between the number of Fusarium culmorum and F. avenaceum, fungi found on culm base parts of stalks of seven winter wheat cultivars, and preceding crop type as well as the cultivation system. The research was carried out in Poland, on light soil plots of a Lower Silesia-based experimental station subordinate to the Institute of Soil Science and Plant Cultivation (IUNG). The loglinear and correspondence analyses proved varying immunity of particular wheat cultivars to F. culmorum and F. avenaceum fungi. There were also observed significant differences in Fusarium diseases of wheat as dependent on precipitation and temperature in the growing season. The Kobra cultivar was highly resistant to F. avenaceum. The lowest amounts of F. culmorum fungi were detected in the culm base parts of the Izolda cultivar. The cultivation of corn, as a preceding crop for oats and for spring wheat, did significantly differentiate varieties of fungi in the cultivation systems examined. In the plough cultivation system, wheat was mainly infected by Fusarium culmorum, whereas in direct sowing, particular cultivars of wheat were mostly infected by F. avenaceum.

Mountain pine (Pinus mugo) is the most important component of the sub−alpine and alpine zone in the Tatras, and other ranges of central Europe. In Poland, only population from the Karko− nosze Mts. has been studied in terms of phytopathological threats so far. There is not much information on the diseases caused by fungi in the mountain pine from other regions either. The mycological analyses of infected mountain pine needles were conducted for years 2013 and 2014 in subalpine zone of the Tatra Mts (Morskie Oko, Hala Gąsienicowa, Hala Kondratowa). Pine needles rust Coleosporium tussilaginis and yellow spots Lophodermium conigenum were found. To a lesser extent the needles were spotted with symptoms caused by Mycosphaerella dearnessi. Infection symptoms and fraction of the infected needles on one shoot were determined. The isolation of fungi was conducted in end of July, when the intensity of disease symptoms on needles was the highest. The main species isolated from the infected needles was Lophodermium spp., while the dominant one was L. conigenum. Except for this pathogen, L. pinastri, Botrytis cinerea and Epicoccum niger were identified together with several saprotrophic species, e.g. Aspergillus niger. The most frequent disease of mountain pine needles in the Tatra Mts. is pine needles rust. Observations in the Karokonosze and the Tatra Mts. indicate that both populations suffer from similar diseases. The differences show that pathogens adapt to different environmental conditions. Therefore constant monitoring of the health status of mountain pine growing in nature seems to be necessary.
