Plant Health

The Panel on Plant Health (PLH) provides independent scientific advice on the risk posed by plant pests which can cause harm to plants, plant products or biodiversity in the EU. The Panel reviews and assesses those risks with regard to the safety and security of the food chain.

PLH Panel Members are scientists from across Europe with expertise in:

  • Pest risk assessment – with particular regard to quantitative methods
  • Quantitative pathway analysis
  • Spatial-temporal modelling of pest dynamics, including aerobiology
  • Experimental design and statistical data processing
  • Systematic literature review
  • Plant pathology – diseases caused by phytopathogenic micro-organisms, e.g. fungi, bacteria, phytoplasmas, viruses, viroids)
  • Plant disease epidemiology and management
  • Invertebrate pests – phytophagous insects, mites and nematodes)
  • Integrated pest management and biological control
  • Weed science – including parasitic plants
  • Landscape ecology – in relation to plant health.

Risk assessment in plant health

Established to build mutual understanding of risk assessment principles in the plant health sector and to provide increased transparency in the current risk assessment among Member States and EFSA.
