(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 ... -
Modellierung der Wirkungsdauer von Getreidefungizieden und deren Implementierung in Online-Entscheidungshilfen unter besonderer Berücksichtigung von Zymoseptoria tritici
(2015-03-31)One important ecopolitical aim of the German federal government relating to integrated plant protection is, to realize applications of plant protection products environmentally friendly and resource-conserving dependent ... -
Fusarium-Artenspektren an Halmbasis und Körnern von Weizen in unterschiedlichen Weizenfruchtfolgen
(2013-12-03)In the present study the composition of Fusarium species spectra on stem bases and grains of wheat and their colonization rates were investigated under the conditions of a wheat crop rotation experiment existing since 2006. ... -
Studies on Ramularia Leaf Spots on Barley - Resistance Phenotyping, Epidemiology and Pathogenicity
(2013-10-31)The deuteromycete, Ramularia collo-cygni (Rcc) has gained increasing importance as the causal agent of a novel leaf spot disease, Ramularia leaf spot (RLS), on barley. The disease occurs conspicuously late in the growing ... -
Improvement of Winter Oilseed Rape Resistance to Verticillium longisporum - Assessment of Field Resistance and Characterization of Ultrastructural Plant Responses
(2013-07-04)Recent years have seen an intensification of oilseed rape (OSR) cultivation, which, together with shorter crop rotations has led to a rapid increase in infestation by the soil-borne vascular pathogen V. longisporum. The ... -
Effects of rising air and soil temperatures on the life cycle of important pathogens in oilseed rape (Brassica napus L.) in Lower Saxony
(2013-04-16)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, which will have effects on both crop and fungal pathogen development. Within the research framework ... -
