Description and Uses

The antibiotic streptomycin is an important and effective chemical for the management of bacterial diseases of fruit trees (especially apple), woody ornamentals, and vegetables. Streptomycin was initially discovered in 1944 and was one of the first antibiotics to be utilized in clinical medicine to control human diseases, and is still important as a feed amendment for growth promotion in agricultural animals. The widespread and diverse usage of streptomycin has contributed to the currently observed global streptomycin resistance (SmR) problem. This problem is especially critical in plant disease management, as there are few alternatives to streptomycin available and, as a consequence of increased usage, SmR has been increasingly observed among bacterial plant pathogens.

Antibiotic substance produced by aerobic fermentation. Antibacterial (tuberculostatic).
