Activity 2.1

Sustainable production and management of
biological resources from land, forest and
aquatic environment

KBBE-2010-1-2-06 Deepened and enlarged
cooperation between phytosanitary (statutory
plant health) research programmes - ERA-NET
  • The aim is to prevent the introduction into the
    community of organisms harmful to plants or plant
    products or their spread within the Community.
    Due to climate changes and globalization, new
    threats are continuously emerging and the number
    and complexity of plant health problems increases
    every year, requiring enhanced research efforts.

Funding scheme Coordination and Support Action
(supporting action). The requested European
Community contribution shall not exceed EUR 1 000
000.

KBBE-2010-1-2-05 Integrated pest management in
farming systems of major importance for Europe
  • better targeted use of all available pest
    control measures, including preventive measures,
    observation and pest monitoring, pesticides and
    biocontrol agents,
  • modelling and experimentation, including
    physiological and molecular understanding of
    plant-pathogen interactions and development of
    symptoms
  • targeting farming systems in which reduction of
    pesticide use and better control of pests and
    pathogens is expected to have major effects at
    the European scale

Funding scheme Collaborative Project (large
scale integrating project). The requested
European Community contribution shall not exceed
EUR 9 000 000.

OLIVE OIL
? Samples from Czech market
23 extra virgin olive oils
from
organic farming (O1 O23) 23 extra virgin olive
oils

from conventional farming (C1 C23)
EXTRA VIRGIN OLIVE OIL The oil obtained from the
fruit of the olive tree solely by mechanical or
other physical means under the conditions.
particularly thermal conditions, that do not lead
to alternations in the oil, and which has not
undergone any treatment other than washing,
decantation, centrifugation and filtration.
? Method of analysis GCx GC/TOF MS
