Growers Gain Another Tool for Fire Blight Control in California

California pome fruit growers recently gained another tool to help fight against fire blight: Kasumin bactericide. Arysta LifeScience announced that the California Department of Pesticide Regulation has granted registration for the use of Kasumin on apple and pear crops in California. Arysta LifeScience expects walnuts and cherries to be added in the coming months.


“The addition of Kasumin, with its unique mode of action, is a boost to apple and pear growers battling fire blight,” said David Davies, U.S. Herbicides & Fungicides Marketing Manager, Arysta LifeScience. “Kasumin is an effective tool to help fight this destructive disease, including streptomycin-resistant isolates in apples and pears.”

Kasugamycin, the unique active ingredient in Kasumin, features a high level of preventive activity, making it effective on a wide array of plant pathogenic bacteria, including fire blight. Kasumin is available as a liquid formulation, and field testing has shown it can be easily tank-mixed with other fungicides to increase the spectrum of disease control.

Arysta LifeScience recommends Kasumin as part of a resistance management program and says the product is most effective when it is incorporated in a rotation program. The company says Kasumin shows no cross-resistance to other bactericides, and features a 12-hour restricted-entry interval and 90-day pre-harvest interval.
