Streptomycin resistance of Erwinia amylovora in Israel

Fireblight due to Erwinia amylovora (EPPO A2 quarantine pest) was first detected on pear trees in Israel in 1985, and since 1986 streptomycin has been the preferred bactericide for controlling the disease. Strains resistant to streptomycin were found for the first time in a pear orchard in 1991, in the south of Israel. During 1994 and 1995, 45 orchards of pear, apple, loquat and quince from all over the country were sampled and tested for streptomycin resistance. Resistant strains were isolated from 8 sites in the Hadera region (central coastal plain) and from a few orchard in the Golan Heights and Upper Galilee. These results showed that streptomycin resistance is well established in the populations of E. amylovora in Israel.
