Abstract
Severe infection with fire blight has occurred on a pear orchard in the desert area known as Nobaria (North of Tahrir District) in Egypt, since 1992. Different strains of Erwinia amylovora were identified, according to their cultural and biochemical characters, where no differences could be distinguished on their pathological basis.
Copper compounds, i.e., Copper sulfate, Copper oxychloride, Man coper, Cuprozan, and Koppack E were insufficient against different strains of both laboratory and field experiments.
Streptomycin sulfate, Streptopenicid, and Chloramphenical were effective against E. amylovora, where streptomycin was the best.
Oxytetracycline was not effective.
The Sumitomo compound S-0208 was similar to streptomycin in its effect on E. amylovora strains.
