The Environmental Protection Agency (EPA) and California Department of Pesticide Regulation recently accepted a Section 18 petition to allow the use of Kasumin 2L (kasugamycin) to control bacterial blast (Pseudomonas sp) in almonds. The registration allows up to two applications under anticipated cold or freezing conditions on almonds at a use rate of 64 fl. oz. per acre from February 2, 2024, through petal fall. Application after petal fall is prohibited. Kasugamycin may only be used during bloom.

The approval applies to the counties of Butte, Calaveras, Colusa, Contra Costa, Fresno, Glenn, Madera, Merced, Placer, San Joaquin, Stanislaus, Sutter, Tehama, Yolo, and Yuba.

Growers interested in this application are heavily encouraged to reference the Almond Board of California’s Honey Bee Best Management Practices as well as the Quick Guide for Applicators (in English & Spanish) to ensure pollinator health is maintained. As stated in these practices, growers should only use applications when absolutely necessary and should only make applications in the late afternoon or evening, when bees and pollen are not present.
