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.
|Crop or Crop Group||Rate of product per hectare (L / ha)||Remarks||Pre-harvest interval|
|Pome fruit||5.0||Begin applications at 20-30% bloom or when conditions favour disease development; Repeat at 7 day intervals; do not apply more than 4 applications per season.||90 days|
|Fruiting vegetables (field and greenhouse)||1.2||Begin applications when conditions favour disease development; a minimum interval of 7 days between applications is required; do not use more than 3 applications per season.||1 day|
|Walnuts||5.0||Begin applications when conditions favour disease development; a minimum interval of 14 days between applications is required; do not use more than 4 applications per season.||100 days|
Follow all other precautions and directions for use on the Kasumin® bactericide label carefully. Consult individual crop and disease control recommendations on the Kasumin® bactericide label for additional use restrictions.
Kasumin® bactericide should be used in an Integrated Pest Management program and in rotation with other management strategies to adequately manage resistance. Consult provincial guidelines and local extension specialists for monitoring protocols and disease management recommendations.
We wish to thank the personnel of Arysta LifeScience North America, Agriculture & Agri-Food Canada, Pest Management Centre and US IR-4 Program for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
