Regulierung von Phytoplasmosen im ökologischen Weinbau - Risikoanalyse und Lösungsansätze Organic Eprints
Maixner, Michael; Langer, Markus.
Die Schwarzholzkrankheit, eine Phytoplasmose, ist ein zunehmendes Problem besonders im Steillagenweinbau. Der Infektionsdruck wird bestimmt durch das Vorhandensein krautiger Wirtspflanzen sowohl der Phytoplasmen als auch der krankheitsübertragenden Zikade Hyalesthes obsoletus, deren Larven an den Wurzeln dieser Pflanzen leben. Art und Intensität der Bodenbewirtschaftung und -begrünung beeinflussen daher das Risiko durch die Schwarzholzkrankheit. Ziel der Untersuchung war es, Informationen über das Infektionsrisiko durch Phytoplasmosen in ökologisch bewirtschafteten Weinbergssteillagen zu erarbeiten und Ansätze für Regulationsstrategien zu entwickeln. Auf den ökologisch bewirtschafteten Rebflächen wurden neben Ackerwinde auch Brennnessel und Zaunwinde als...

Monitoring of total contents of copper in organically and conventionally managed soils. Part 1: Study plan and preliminary sampling of copper and other anthropogenic induced heavy metal contents in vineyard soils Organic Eprints
Riepert, Frank; Steindl, Anna; Eibach, Rudolf; Maixner, Michael; Reichmuth, Christoph; Strassemeyer, Jörn; Strumpf, Thomas.
The project aims to develop a survey designed for the representative assessment of copper contents in vineyard soils. The method development for the sampling of adequate monitoring areas is based on a preliminary survey of load distribution as well as on exposure assessment on selected areas of some typical vinery sites in Rheinland-Pfalz, differently managed and with different use history. Additionally to the sampling of selected areas, which reflects the spectrum of the load situation in viticulture, chemical quantitative analysis of soil samples collected from areas of known mode of cultivation and history followed by biological standard tests will be conducted. Obtained findings will serve for further method development, for preselection of adequate...
