TRADE OR OTHER NAMES: Streptomycin is also called streptomycine, streptomycin sulfate or streptomycin nitrate. Trade names include Agri-mycin-17, Plantomycin; Agrept, Rimosidin, and AS-50 (1, 207).

REGULATORY STATUS: Streptomycin is a General Use Pesticide (GUP) registered for use on fruits and vegetables. It may also be used on nonfood crops such as tobacco and greenhouse ornamentals (351).

INTRODUCTION: Streptomycin is a human antibiotic drug which also is used to control bacteria, fungi, and algae in crops. It is an aminoglycoside with systemic action that is used on fruits, vegetables, tobacco, ornamentals, and in ponds and aquaria (207, 351). It controls a number of commercially important bacterial plant pathogens including fireblight of pear and apple, walnut blight, tomato canker, bacterial canker, angular leaf blight, and others. Gram positive species of bacteria are much more susceptible to its action than gram negative species (223). The EPA has classified it as Toxicity class IV- relatively non-toxic. Products containing streptomycin bear the Signal Word "Caution" because of its potential to cause skin reactions. It is available as a water soluble powder, pellets or emulsifiable concentrate (351).





Streptomycin is an off-white powder derived from Streptomyces griseus bacteria (223). It is odorless and has a slightly bitter taste. The salt forms are hygroscopic but are not affected by exposure to light or air (225). Neutral solutions of streptomycin are stable for weeks at temperatures below 25 degrees C. Streptomycin is more active at an alkaline pH (347). It is unstable in strong acids and alkalis. It is incompatible with alkaline materials (1).
