Epidemiological studies on wheat blast (Magnaporthe oryzae pathotype Triticum, MoT) with special reference to potential biocontrol
(2024-07-18)Wheat blast (WB) is an economically important disease caused by Magnaporthe oryzae pathotype Triticum (MoT) pathogen. It may cause up to 100% yield loss, concerning global food security. The epidemiology of WB, seed ... -
Uncovering the role of falcarin-type polyacetylenes in carrots for enhanced resistance
(2024-06-05)Falcarin-type polyacetylenes (PA) are a group of putative plant defense metabolites produced by carrot plants. However, the elucidation of PA biosynthetic pathway and the biological function of PA in carrot plants are not ... -
Interactions between endophytic Metarhizium brunneum and oilseed rape plants: effects on plant health and possible mechanisms
(2023-10-18)Fungi of the genus Metarhizium, belonging to the order Hypocreales, are well-known entomopathogens that primarily infect insects. However, recent research has revealed their multifunctional lifestyles, including their ... -
Characterization of Leptosphaeria maculans races in Germany and studies on resistance of Brassica napus to blackleg disease
(2023-03-23)Leptosphaeria maculans, a phytopathogen causes blackleg disease, is an economically significant biotic stress that affects oilseed rape (B. napus) production worldwide. Blackleg disease can be controlled by stubble management, ... -
Characterisation of genotypic and tissue specific resistance in oilseed rape (B. napus) against Sclerotinia sclerotiorum
(2020-01-03)Sclerotinia sclerotiorum is a necrotrophic ascomycete and the causal agent of stem rot disease, an economically important constraint in the cultivation of oilseed rape (Brassica napus L.). Since cultivar resistance is a ... -
Occurrence and Importance of Foliar Diseases on Maize (Zea mays L.) in Central Europe
(2018-07-09)In the last decade, the acreage of maize has increased continuously in Central Europe due to its high yield and diverse uses as food, feed and bio-energy. This has led to more intense maize cultivation in many regions with ... -
Europäisches Rassen-Monitoring und Pathogenesestudien zur Turcicum-Blattdürre (Exserohilum turcicum) an Mais (Zea mays L.)
(2018-05-28)In the last few years, the importance of Exserohilum turcicum, the causal agent of Northern Corn Leaf Blight (NCLB), has increased in European maize growing regions. The infestation of maize leafs by NCLB reduces the ... -
Unfavorable environmental conditions: Consequences for microbial metabolism and C stabilization in soil
(2017-11-21)Soil microorganisms are primary drivers of biogeochemical cycles, making them an important link between pedosphere and atmosphere. Soil microbes control the carbon (C) transfer from terrestrial ecosystem to the atmosphere ... -
Influence of agronomic practices on the development of soil suppression against cyst-forming plant-parasitic nematodes
(2017-05-05)Cyst-forming nematodes are a major group of plant pests of economic importance worldwide. There are well-documented cases of suppressive soils where plant-parasitic nematodes are maintained at very low population densities ... -
Phänotypisierung von Resistenzquellen und Charakterisierung von Resistenzfaktoren in Brassica-Arten gegenüber Sclerotinia sclerotiorum, dem Erreger der Weißstängeligkeit.
(2017-03-21)The present study was part of the international PLANT-KBBE III – joint research project MONARCH (White Mold Brassica napus Resistance Challenge, subproject B). The project assignment included the identification of new ... -
Effect of temperature on the interactions between beet cyst nematodes (Heterodera schachtii and Heterodera betae) and sugar beet
(2016-10-28)Climate change is expected to cause a mean annual temperature increase in Germany of 2 °C by 2050 and up to 4 °C by 2100. This is likely to have effects on crop development and pathogen development as well. For this Ph.D. ... -
Population structure of Magnaporthe oryzae from different geographic regions and interaction transcriptomes with rice genotypes at high temperature
(2016-09-16)It is currently hypothesized that climate change may lead to global warming, and temperatures might increase by 2-5°C at the end of the twenty-first century. However, the consequences of the expected temperature elevation ... -
Nitrogen Efficiency of Winter Oilseed Rape and its Prediction by Hyperspectral Canopy Reflectance and Electrical Capacitance
(2016-07-01)Oilseed rape is the third most important oil crop worldwide. Under many conditions it is characterised by relatively low nitrogen efficiency. In Germany a nitrogen supply of 240 kg N ha 1 is aimed at which derives from ... -
Elimination of Clavibacter michiganensis subsp. michiganensis from tomato cultures and seeds by highly sensitive detection methods and effective seed treatments
(2015-09-04)The phytopathogenic bacterium Clavibacter michiganensis subsp. michiganensis (Cmm), causing bacterial canker of tomato, is the most serious bacterial pathogen of tomato worldwide. The bacterium is considered as A2 ...

Einfluss der Bestandesarchitektur auf die Ertragsbildung im Winterraps (Brassica napus L.)
(2015-08-11)In the present study, a three-factorial field trial, consisting of the factors cultivar, seed rate and growth regulating fungicides was conducted to analyze the relationship between crop architecture of a winter oilseed ... -
Effect of climate change on population dynamics and damage potential of insect pests on oilseed rape
(2015-05-21)Biotic stress such as pests can cause high yield losses in agricultural crop systems. It has been estimated that global warming will increase these rates. Thus, the impact of global warming on the distribution and abundance ... -
Weeds in a changing environment
(2015-04-10)In the course of the past decades, various impacts of climate change have been recognized to pose a challenge to arable production systems. Among others, shifts in the species composition of weed communities, particularly ... -
