The widespread use of brominated flame-retarded products in the last two decades has resulted in an increasing presence of bromine in thermal processes such as waste combustion and accidental fires. Brominated and brominated-chlorinated dibenzodioxins and dibenzofurans (PBDDs/PBDFs, PXDDs/PXDFs) are micropollutants of concern arising from such processes.(More)
Unterentwickelte abgestorbene Früchte (Fruchtmumien) können an bestimmten Sorten von Tafeläpfeln wie ‘Elstar’ oder Zieräpfeln wie ‘Golden Hornet’ über 12 Monate lang am Baum verbleiben und werden dadurch zum geeigneten Substrat für Pilze. Eine Methode zum Nachweis der Besiedlung solcher Fruchtmumien durch wichtige pilzliche Erreger von Fruchtfäulen wurde(More)
Botrytis cinerea is a major plant pathogen, causing gray mold rot in a variety of cultures. Repeated fungicide applications are common but have resulted in the development of fungal populations with resistance to one or more fungicides. In this study, we have monitored fungicide resistance frequencies and the occurrence of multiple resistance in Botrytis(More)
In the Lower Elbe region of Northern Germany and in other Northern European fruit production areas, about 80 % of all storage rots of apples are caused by Neofabraea alba and N. perennans. Other pathogens include Colletotrichum acutatum, Monilinia fructigena, Phaci­diopycnis washingtonensis, Neonectria galligena, Botrytis cinerea, Penicillium expansum and(More)
Im Sommer 2010 wurde im südlichen Niedersachsen an Heidelbeeren (Vaccinium corymbosum) insbesondere in jüngeren Anlagen der Sorte ‘Duke’ ein Triebsterben beobachtet, welches auch in den beiden Folgejahren auftrat. Die plötzlich einsetzende Chlorose und Nekrose einzelner Zweige war mit einer Zerstörung des Kambiums sowie mit längsstreifigen Verbräunungen im(More)
‘Long-canes’ which produce the first fruit crop within three months of being planted in spring are becoming the preferred raspberry nursery material in north-western Europe. However, infections of these canes by grey mould fungi (Botrytis spp.) are common. In a survey of Botrytis infections in 22 batches of long-cane plants from six different nurseries,(More)
Sooty blotch and flyspeck (SBFS) fungi colonise the surface of a range of fruits, especially apple, without penetrating the cuticle. Economic damage results from the exclusion of severely affected fruit batches from being marketed as table apples. A study of SBFS was conducted in 2007–2012 in the two largest German apple production areas, i.e. the Lake(More)
Sooty blotch and flyspeck (SBFS) is a complex of more than 80 fungal species in 24 genera, mostly belonging to the order Capnodiales within the Dothideomycetes. Colonies of these epiphytes become visible on the surface of apples in mid- to late summer. Several species of SBFS fungi have been previously identified from apples in Germany, but little is known(More)
In zwei stark durch Triebsterben geschädigten Heidelbeer-Junganlagen der Sorte ‘Duke’ wurden Wirkungsversuche mit den Fungiziden Cuprozin WP (aktiver Wirkstoff Kupferhydroxid), Malvin WG (Captan), Switch (Cyprodinil und Fludioxonil) und Signum (Pyraclostrobin und Boscalid) durchgeführt. Behandlungen wurden zweimalig während des Blattfalls im Herbst 2011(More)
