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.

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.
