Kasumin has now gained a full ACVM registration label claim for Psa management. Kasumin is included on the KVH recommended product list and works as a preventative bactericide. The active ingredient kasugamycin has a bactericidal mode of action that is different from other bactericides such as streptomycin. Kasugamycin is active against pathogenic fungi and bacteria in plants and has never been employed as a human or veterinary medicine.

Kasumin must be used in a programme with other plant protection products that are active on and recommended for the management of Psa and should be reserved for use in high-risk situations. One pre-flower Kasumin is allowed under Crop Protection Standard rules, with a second application requiring a JA (Justified Approval). Follow user guides.
