Used as an antibiotic in agriculture, particularly effective against bacterial diseases in rice, fruits, and vegetables. It controls pathogens like *Xanthomonas* and *Pseudomonas* species, helping prevent blight, leaf spots, and fruit rot. Commonly applied as a foliar spray or seed treatment, it works by inhibiting protein synthesis in bacteria. Due to its low toxicity to humans and minimal environmental impact, it is favored in integrated pest management programs. Also used in some laboratory settings for selection in cell culture, especially in plant transformation studies.
