Kasugamycin 6980-18-3 70% TC;6% WP; 3% SL; 2% SL



Introduction: Kasugamycin (Ksg) is an aminoglycoside antibiotic that was originally isolated in 1965, from Streptomyces kasugaensis, a Streptomyces strain found near the Kasuga shrine in Nara, Japan. Kasugamycin was discovered by Hamao Umezawa, who also discovered kanamycin and bleomycin, as a drug that prevent growth of a fungus causing rice blast disease. It was later found to inhibit bacterial growth also. It exists as a white, crystalline substance with the chemical formula C14H28ClN3O10 (kasugamycin hydrochloride). It is also known as kasumin.

ADI 0-0.1 mg/kg b.w.


WHO Classification: U (Unlikely to present an acute hazard)

EC Risk Classification: Harmful: R22          

US EPA Classification (formulation): No concensus across products or no products available

Animals Kasugamycin hydrochloride hydrate orally administered to rabbits was mostly excreted in the urine within 24 h. When injected intravenously to dogs, it was mostly excreted within 8 h. After oral administration to rats at 200 mg/kg, no residues were detected in eleven organs or blood; 96% of administered dose remained in the digestive tract 1 h after administration. Plants Degraded to kasugamycinic acid and kasuganobiosamine; finally degraded to ammonia, oxalic acid, CO2 and water. Soil/Environment Degradation proceeds as in plants.   

Usage: Kasugamycin was introduced by the Institute of Microbial Chemistry and by Hokko Chemical Industry Co., Ltd. It is an aminoglycoside antibiotic used, normally as the hydrochloride salt, against bacteria and some fungi.

Application: (kasugamycin hydrochloride hydrate) Biochemistry Protein synthesis inhibitor. Inhibits binding of Met-RNA to the mRNA-30S complex, thereby preventing amino acid incorporation. Mode of action Systemic fungicide and bactericide with protective and curative action. Inhibits hyphal growth of Pyricularia oryzae on rice, preventing lesion development; comparatively weak inhibitory action to spore germination, appressoria formation on the plant surface or penetration into the epidermal cell. Rapidly taken up into plant tissue and translocated. In contrast, against Cladosporium fulvum on tomatoes, inhibition of sporulation is strong, but inhibition of hyphal growth is weak. Uses Control of fungal and bacterial diseases affecting rice, vegetables and fruit. On rice, it controls diseases caused by Pyricularia oryzae and Burkholderia glumae (bacterial grain rot), with ground and aerial applications, at 20-30 g/ha, and seedling diseases caused by various bacterial pathogens, at 0.3-0.6 g/box. In sugar beet, it controls Cercospora beticola, at 80-100 g/ha. Also used to control plant diseases in various crops: Pseudomonas syringae pv. lachrymans in cucumbers, at 30-60 g/ha; Colletotrichum lagenarium in melons and water melons; Cladosporium fulvum and Corynebacterium michiganense in tomatoes, at 20-40 g/ha; Mycovellosiella spp. in aubergines; Cercospora spp. in celery; Erwinia carotovora subsp. carotovora in potatoes, carrots and onions; Pseudomonas syringae pv. coronafaciens (halo blight) in kidney beans, at 40-60 g/ha; Xanthomonas spp. in paprika; Venturia sp. in apples; Pseudomonas marginalis pv. marginalis in kiwifruit; etc.
