Institute for Plant Protection in Fruit Crops and Viticulture

Head: Prof. Dr. Wilhelm Jelkmann

The Institute for Plant Protection in Fruit Crops and Viticulture is one of 15 specialized institutes of the Julius Kühn Institute (JKI). The lead institute is located in Dossenheim. At this site research on topics in fruit crops is carried out, while the Siebeldingen site (Geilweilerhof) covers research on plant protection in viticulture.

Tasks and main areas of work

The tasks of the institute derive from the German Plant Protection Act and related legal regulations. The institute advises the Federal Government, in particular the Federal Ministry of Food, Agriculture and Consumer Protection (BMELV), on all matters of Plant Protection and Plant Health in the field of fruit crops and viticulture. Its research activities focus on these fields and the specific research tasks defined by BMELV. The institute represents the Federal Government in national and international organizations and working panels (e.g. EPPO, EU) and it is involved in the formulation of regulations and guidelines on plant health. It takes part in the approval procedure for plant protection products. Research activities and sovereign functions are closely interrelated. The institute coordinates joint research activities on plant protection problems and control strategies of national interest. Current examples are control strategies for the cherry fruit fly and the spotted wing drosophila, control of fire blight without use of antibiotics, phytoplasma diseases of fruit crops and grapevine, or esca-disease of grapevine. The results of the institute’s scientific work are made available to federal and state administrative bodies, the scientific community, and growers and consumers as well. The institute organizes technical discussions on specific plant protection problems and communicates their results. Its work includes diverse research activities on phytopathological problems and appropriate control strategies in a wide range of fruit crops, viticulture and hops in both integrated and organic cropping systems.

Assessment of plant protection products

  • Assessment of plant protection products and biocides as well as their active ingredients in the context of the national authorization procedure and the EU evaluation of active ingredients, and drafting proposals for plant protection risk reducing management measures

Pests and Diseases

  • Studies on biology, epidemiology and diagnosis of pathogens and pests and their antagonists for a) basis for plant protection, b) avoiding of introduction and spread of non domestic and invasive species and, c) development of sustainable strategies to avoid appearance or control pathogens and pests, with respect to global climatic changes
  • Characterization of viruses, viroids and other non-beneficial organisms as well as development of diagnostic methods with respect to quarantine issues and securing of phytosanitary quality of propagation material for fruit crops and grapevine
  • Population dynamics, epidemiology, disease potential and forecasting of pests and diseases for the development and optimization of integrated plant protection measures in fruit crops and viticulture
  • Estimation of new threats by pests and diseases as consequence of global warming and change of cultural practices in fruit crops and viticulture, including investigations on biology of newly appearing organisms as well as drafting  strategies for their prevention, confining and treatment
  • Investigations on the causal agent of fire blight and development of strategies for treatment without use of antibiotics in integrated and organic fruit production
  • Research on insects and nematodes as vectors of virus diseases and phytoplasmas as well as development of strategies for their control, with respect to global climatic changes.

Plant protection strategies, habitat management

  • Development of concepts and sustainable strategies for integrated production in fruit crops and viticulture with the aim of risk reduction in pesticide application and the optimization of a consumer friendly production
  • Working on non-chemical treatments and disease regulation strategies, including habitat management measures on pests in organic fruit production and viticulture
  • Investigations on the function of scattered orchard and commercial fruit production and viticulture in steep slopes, in particular with regard to biodiversity
  • Biology of grapevine decline diseases and development of avoidance strategies
  • Investigation of consequences of plant protection on post harvest quality (fruit storage diseases, vine fermentation and vinification)

Resistance

  • Investigations on resistance of tree fruits and grapevine by studies on host-pathogen-interactions for fungal, viral, bacterial and phytoplasma diseases
