Collaborative project: Development of biological plant protection strategies against invasive non-regulated stink bug species with high damage potential - subproject B (Project)
...At the core of this research will be monitoring of the newly invaded areas for natural enemies, e.g. egg parasitoids in the genus Trissolcus, of these two stink bugs, the assessment of their biological control potential, and the establishment of breeding strains of potential biological control agents. Various field entomological methods will be applied to monitor the stink bugs and their natural enemies (work package 1). Species, which are shortlisted as potentially effective antagonists, will be reared to build up strains meant for commercial use (work package 2). ...Based on the results obtained in work packages 1 through 3, pest management strategies for the control of these invasive stink bugs will be developed. ...

Soil organisms and their performance in an agroecosystem influenced by elevated atmospheric CO2 and different N-fertilisation (Project)
...Worldwide increasing CO2 concentrations in the atmosphere form the background for a field experiment in an agroecosystem. Biodiversity and performance of soil organisms has been studied under the conditions of elevated atmospheric CO2 by fumigating the standing crop. The carbon of the CO2 passes through the plants via stomatical uptake into the soil as root exudates or is deposited as dead roots and residues. The distribution of the additional carbon within the food chain can be analysed with stable isotopic techniques because the fumigated CO2 is depleted with 13C. Conclusions can be drawn on the carbon dynamic under the conditions of climate change by comparison these isotope results with those detected in other compartments of the agroecosystem. ...

SPP 1315: Effects of soil organic matter molecular conformation and substrate additions on the formation and release of xenobiotics bound residues (Project)
...The objective of this study is to determine the effects of SOM structural conformation on the bioaccessibility and biodegradation of the two 14 C-labelled model compounds nonylphenol and phenanthrene. This is on three hypotheses: 1. The formation of bound residues is affected by the structural conformation of SOM. In particular, sorption of xenobiotics to SOM with a high degree of cross-linking induced by polyvalent cations will be less linear because fast partioning is reduced in favour of slow sorption processes. 2. Changes in the physico-chemical environment (pH, electrolytes, temperature) affect the bioavailability of bound residues because they induce changes in the structural conformation of SOM. 3. ...

Characterization of silver protein complexes relating to particle size and surface charge (Project)
...The high reactivity of nano materials can cause interactions between the nano material and surrounding media (e. g. food and incubation media for toxicology and microbiology). ...Hence the influence of protein -as one of the essential ingredients in food and incubation media- on the behavior of silver nano particles of different functionalization will be investigated in this project.

Collaborative project: Development of a granule and liquid formulation based on the entomopathogenic fungus Metrahizium brunneum to control wireworms in integrated and organic potato production. Subproject 2 (Project)
...The five species Agriotes lineatus (L.), A. obscurus (L.), A. sputator (L.), A. sordidus (Illiger) und A. ustulatus Schäller are the most important species in Europe. ...Virulent Metarhizium-strains with efficacy against wireworms were identified in different research groups. E.g. at the Agriculture and Agri-Food Canada (AAFC) the Metarhizium brunneum-strain LRC112 and at the Agroscope (CH) the strain 2825 are promissing candidates for the development of a Biocontrol Agents (BCA). ...

PathOrganic - Risks and Recommendations Regarding Human Pathogens in Organic Vegetable Production Chains (Project)
...PathOrganic assesses risks associated with the consumption of fresh and minimally processed vegetables due to the prevalence of bacterial human pathogens (e.g. Salmonella enterica, pathogenic E. coli, Campylobacter spp., Listeria monocytogenes) in organically grown plant produce. ...In order to carry out a meaningful survey and to choose appropriate experimental plans, a model for pathogen transfer to selected plants is built in work package 1 (WP 1) to describe relevant food chains. Based on this model sampling strategies and methodological adjustments are made. A questionnaire is set up to describe current management practices (WP 1). WP 2 of the project is dedicated to surveying the presence of food pathogens in organic plant produce. ...
