Description and Uses
Tetracycline is an antibiotic that has been utilized in disease management situations in which SmR strains of E. amylovora or P. syringae already exist. However, tetracycline does not appear to be as effective as streptomycin in reducing blossom populations of E. amylovora (17). Additionally, strains of P. syringae with resistance to tetracycline have been isolated from pear orchards in Oregon and Washington (18), suggesting that resistance to this antibiotic will probably develop in orchards where it is applied.
