Abstract:
In less than six months after
infection, Erwinia amylovora may
completely destroy a pome tree. This paper
aims to increase awareness of the potential
for developing plant protection strategies
based on natural products. Since the damage
caused by this bacterium are unrecoverable,
we tested in vitro the effectiveness of a
several plant extracts such as Salvia
officinalis, Thymus serpyllum, Pelargonium
odoratissimum, Hedera helix, Ocimum
basilicum, Levisticum officinale, Tagetes
patula, Galium verum and some pesticide
products, on a strain of Erwinia amylovora
isolated from the pomological collection of
"Vasile Adamachi" farm, the University of
Agricultural Sciences and Veterinary
Medicine, Iaşi. The strain was isolated from
damaged pear shoots, after performing
patogenicity test on immature pear fruits.
Following the experiment conducted,
copper oxychloride (Alcupral 50 PU) and
Pelargonium odoratissimum showed a very
good antibacterial activity against EA - A.P.
strain.
