leaves dried they were placed in Petri dishes
containing sterilized water agar. Then, inoc-
ulation was effected place by transferring ei-
ther an inverted 5mmmycelial disc, or a drop
of a spore suspension (5x10
4
/ml) onto the
adaxial leaf surface (wounded or not). Fun-
gicide efficacy was evaluated by measuring
the size of the infection lesion after a 3 (my-
celium) or 6 (spores) day incubation, respec-
tively, in a growth chamber at 18

light. The fungicides pyraclostrobin (0.01%)
and fenhexamid (0.075%) failed to inhibit the
development of Botrytis lesions by the resis-
tant isolates, in all tests. Similar results were
also obtained for boscalid (0.04%), cyprodinil
(0.018% and 0.038%) and fludioxonil (0.012%
and 0.025%) when mycelial discs were used
as the inoculum. In contrast, the fungicides
fluazinam (0.02%) and chlorothalonil (0.15%)
were in all cases effective against all isolates
examined. These results show the inability
of recently introduced fungicides to inhibit
infection by

PROLECTUS
TM
is the trade name of a fenpyra-
zamine (S-2188) basedproduct developedby
Sumitomo Chemical Co., Ltd., as a fungicide
for foliar applications. Fenpyrazamine be-
longs to the chemical family of Pyrazolino-
ne and is characterized by persistent action
and high efficacy against a range of fungi in-
cluding
Botrytis
sp.
, Sclerotinia sclerotiorum
and
Monilia
sp. The product has translami-
nar motion and is active against the agent of
grey mould by inhibiting germ tube elonga-
tion, mycelium growth, and spore formation
in the lesions, as well as preventing lesion
development, by acting on ergosterol bio-
synthesis. No cross resistance was observed
with thedicarboximide, benzimidazole, stro-
bilurin, triazole and pridinamine fungicides.
PROLECTUS
TM
will be released as water dis-
persible granules containing 50% fenpyra-
zamine. The very good profile regarding the
health of operators, workers and bystanders
has lead to a non-classification from a toxi-
cological point of view. Regarding physico-
chemical properties, the results of residue
trials support a 14 to 7 days PHI for grapes
(wine or table) and 1 day PHI for vegetables.
PROLECTUS
TM
is also safe for beneficials.
PROLECTUS
TM
at a dose between 0.8 and 1.2
kg per hectare demonstrates a high efficacy
against
Botrytis cinerea
on grapevine, vege-
table crops and strawberry. Its spectrum of
activity also extends to fungi of the genus
Monilinia
and
Sclerotionia
. As the product
exhibits excellent selectivity and rainfast-
ness, a long-lasting action, favourable tox-
icity classification and a short PHI, PROLEC-
TUS
TM
is therefore an ideal partner for IPM
programs, in line with the needs of a mod-
ern control strategy.
