Overall objective of the project:
There is a high demand on fast and reliable diagnostic tools for identification of viruses and viroids on fruit crops and grapevine. Either laboratory methods are lacking requiring time consuming biotests on indicators or existing tests are not sufficiently validated (lack of data on isolates). At the same time new methods are being developed, resulting in improved diagnostics (reduction in required staff and consumables, increased sensitivity, multiple tests, etc.) and which have to be investigated for phytosanitary purposes and within international competitiveness.
Overall objective of the project:
Viruses and viroids cause a high number of graft transmissible diseases on fruit crops and grapevine. Their characterization is the basics for development and validation of detection methods. Molecular data are also needed to improve conventional or biotechnological breeding. Because of climatic changes and constant development of production techniques continuous research is needed on virus and viroiod diseases.
Overall objective of the project:
Acquiring detailed knowledge on the biology of pests, their population dynamic and changes and their damage potential dependent on biotic and abiotic factors as fundamentals for the establishment of control measures.
Overall objective of the project:
Research on biological and biotechnical methods and the application of selective pesticides (e.g. pheromones, plant derived insecticides, Attract/Bait & Kill, entomopathogenic nematodes).
Overall objective of the project:
Investigations on effects of plant protection products and methods on the population density and dynamics of relevant beneficial arthropods in fruit crops and viticulture (e.g. predatory mites, parasitoid wasps, aphid and scale antagonists), including the development of test methods in a sequential scheme (laboratory, semi-field, field); development of methods to examine the efficacy of pheromones in the field; development of a standardized system to test insecticides to control grape berry moths using artificial inoculation with eggs; improvement of the method for testing side effects of plant protection products on predatory mites.
Overall objective of the project:
Evaluation of benefits of the use of plant protection products with respect to economic and sustainable production of fruit crops and wine.
Overall objective of the project:
Virus- and phytoplasma diseases, e.g. grapevine leafroll or Flavescence dorée are regulated by quarantine or certification systems. The development of diagnostic methods and their validation are a prerequisite to reduce phytosanitary risks.
