Detailed Product Description
Rice / vegetables / fruit Pesticides Insecticide kasugamycin fungicide
Description:
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 which could 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 ydrochloride). It is also known as kasumin.

Applications:
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. Phytotoxicity Non-phytotoxic to rice, tomatoes, sugar beet, potatoes and other vegetables, but slight injury has been noted to peas, beans, soya beans, grapes,
citrus, and apples. Formulation types DP; GR; SL; UL; WP. Compatibility Incompatible with pesticides which are strongly alkaline. Selected products: 'Kasugamin' (Hokko); 'Kasumin' (Hokko)

| 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. |
