Arysta LifeScience North America and the Pest Management Regulatory Agency (PMRA) recently announced the registration of Kasumin® (kasugamycin) bactericide for several crops in Canada. This is the first registration for this active ingredient in Canada and marks an important milestone in addressing some of the most important diseases affecting pome fruit, fruiting vegetables and tree nuts. This product and the diseases it controls have been identified for many years as an important disease management tool needed by Canadian producers.

Kasumin® bactericide is registered for control or suppression of fireblight of pome fruits (apples, pears, quince), bacterial spot and stem canker of field and greenhouse fruiting vegetables (tomatoes, peppers, eggplant) and walnut blight of walnuts. The following table provides a summary of the crop registrations on the new Canadian Kasumin® bactericide label. Consult the full product label for detailed instructions, precautions and restrictions.
