Kanosamine, a constituent of kanamycin , is an antibiotic produced by Streptomyces and Bacillus that can inhibit cell wall synthesis in plant-pathogenic oomycetes (MIC = 25 μg/ml for P. medicaginis M2913) and certain fungi as well as some bacterial species (MIC = 400 μg/ml for S. aureus). It has been explored as an alternative and/or supplement to synthetic pesticides and genetic resistance of crop plants for the management of plant disease.
