Abstract
In VitroSusceptibility ofErwinia Amylovora(Burrill) Winslowet al.Strain Isolated from Pear to Several Plant Extracts and Different PesticidesIn less than six months after infection,Erwinia amylovoramay 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 asSalvia officinalis,Thymus serpyllum,Pelargonium odoratissimum,Hedera helix,Ocimum basilicum,Levisticum officinale,Tagetes patula,Galium verumand some pesticide products, on a strain ofErwinia amylovoraisolated 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) andPelargonium odoratissimumshowed a very good antibacterial activity against EA - A.P. strain.
