port of nutrients by fertilization. By increas-
ing the content of organic matter and of the
macro elements in soil samples, microbial
biomass and the total number of different
groups of microorganisms was increased.
There was also a change with regard to how
frequently the groups of fungi appeared in
cultivated soils in comparison to non-culti-
vated soils. Sclerotia of
Botrytis sp, Sclerotium
sp
were isolated
from the soil of the green-
house where solarization had taken place

The project “SustUse Fumigants” is funded
by the European Union under the “LIFE +
Environment Policy and Governance 2008”
and is intended to promote the sustaina-
ble use of chemical fumigants and the pro-
motion of non-chemical practices (e.g. soil
solarization, resistant rootstocks and bio-
logical control agents) for the control of soil-
borne pathogens in the horticultural sector,
in two agro-ecosystems of Mediterranean
agriculture (Greece and Italy) and in a sys-
tem typical for Central Europe (Poland). The
project encourages the judicious use of pes-
ticides by applying principles of Integrated
Pest Management (IPM) in order to support
the EU policy for successful and sustainable
use of pesticides.
The specific objectives of SustUse are the
following:
•
To promote the wider adoption of more
sustainable crop protection strategies for
soil-borne diseases in horticulture
•
To promote the sustainable use of chem-
ical fumigants in horticultural cropping
systems
•
To maintain competitiveness of European
horticulture in a globalized market, and in
particular Italian, Greek and Polish mar-
kets.
•
To increase effectiveness of research on
sustainable use of pesticides
•
To promote the awareness of growers,
fumigators, advisors, policy makers and
general public on sustainable crop pro-
tection strategies at National and Europe-
an Level.

This trial examined the suppressive ability of
two different composts on the tomato soil-
borne pathogen
Fusarium oxysporum
f.sp.
radicis-lycopersici
. The first compost was pre-
pared using a mixture of agricultural wastes
(olive press cake and olive leaves) while the
second utilized the organic fraction of mu-
nicipal solid waste. Both composts were
used at a low ratio mixture (5-10% w/w) with
sphagnum peat in soilless plant growth me-
dia, due to their high electrical conductivity.
The results showed great potential for the
suppression of the pathogen by both com-
posts. Disease reduction ranged between
