(2011-07-20)Clavibacter michiganensis subsp. michiganensis is a world wide spread, Gram-positive bacteria that causes the bacterium canker and wilt on tomatoes and mainly infests the xylem vessels of ... -
Ramularia collo-cygni an Gerste
(2011-07-04)A differentiation tool for symptomatically similar barley diseases developed in the course of researching this doctoral dissertation has wide practical applicability. However, R. collo-cygni ... -
Lethal and sublethal effects of insecticides on mortality, migration and host searching behaviour of tersilochine parasitoids on winter oilseed rape
(2011-06-30)Oilseed rape crops are attacked by various economically important insect pests that require frequent treatments of broad spectrum insecticides. The extensive usage of insecticides might ... -
Einflussfaktoren der Mykotoxinbildung durch Ährenbefall mit Fusarium spp. in verschiedenen Winterweizenfruchtfolgen
(2011-04-07)In the present study agronomic and climatic factors contributing to mycotoxin production in wheat ears by Fusarium spp. were examined under controlled and field conditions. Particular ... -
The biological role of Fusarium graminearum mycotoxins
(2011-01-27)F. graminearum is an important pathogen that causes head blight and root rot in wheat and ear and root rot in maize. Because of its toxigenic nature most of the diseased crops are found to ... -
Effect of Brassica genotype on the infestation by cabbage stem weevil Ceutorhynchus pallidactylus (Mrsh.) (Col.: Curculionidae) and the parasitism of stem weevil larvae
(2010-12-21)The search for plant resistance to insect pests in oilseed rape (Brassica napus L. var. oleifera Metzg.) is still in an early stage of development. In this study, a wide spectrum of ... -
Entwicklung eines Verfahrens zum biologischen Abbau des Inokulums strohbürtiger pilzlicher Pathogene im Getreide- und Rapsanbau auf Basis des pilzlichen Antagonisten Microsphaeropsis ochracea
(2010-12-08)This work deals with the degradation of the inoculum of straw- and soilborne phytopathogenic fungi, during crop and rapeseed production, by the fungal antagonist Microsphaeropsis ochracea. ... -
Identification of genes induced in the vascular pathogen Verticillium longisporum by xylem sap metabolites of Brasscia napus using an improved genome-wide quantitative cDNA-AFLP
(2009-11-25)Functional transcriptomics is vital in biology. Comparative analysis of the transcriptome in different physiological or developmental stages facilitates the assignment of biological functions ... -
Einfluss von Kohlfliegenbefall auf die Infektion und Schadwirkung von Verticillium longisporum und Phoma lingam an Raps
(2009-07-10)The present work is dealing with the impact of cabbage root fly (Delia radicum) on infections and damage potential of V. longisporum and P. lingam on oilseed rape. Between 2005 and 2008 ... -
Ecology and Molecular Characterization of Neozygites tanajoae (Entomophthorales: Neozygitaceae) a fungal pathogen of the cassava green mite
(2009-03-20)For the biological control of the cassava green mite (Mononychellus tanajoa, Bondar), Brazilian strains of the entomopathogen Neozygites tanajoae were recently introduced into Africa to ... -
Agronomic approaches in yield and quality stability of high oleic sunflowers (Helianthus annuus L.)
(2009-02-04)The high oleic (HO) sunflower has a high potential for industrial use such as oleo chemistry, bio lubricants or bio diesel. Oil from recent high oleic sunflower varieties contains up to 90 ... -
Pilzkrankheiten in Körnerfuttererbsen (Pisum sativum L.) – Diagnose, Epidemiologie, Ertragsrelevanz und Bekämpfung
(2009-01-09)The data for this thesis is based on a Germany-wide monitoring that was carried out in the years 2005 to 2007 to record the pathogen-spectrum in field peas. Additionally, a survey of the yield-relevance of the occurring ... -
Development and application of LC-MS-based differential metabolic profiling in plant systems
