- Bactericide



Pome fruit growers now have another tool to help fight destructive bacterial disease like fire blight. The active ingredient, Kasugamycin, features a unique site of activity different from all other bactericides, which makes it an effective component of any resistance management strategy. ASUMIN is currently registered for use in over 20 countries worldwide, and is new to the United States. Please check back to see when your state receives registration.

  • Active ingredient (Kasugamycin) has a unique mode of action
  • No cross-resistance to bactericides or other products
  • Effective control of fire blight, including streptomycin-resistant isolates in apples and pears
  • 12-hour REI and 90-day PHI

KASUMIN is a Group 24 bactericide. There are no other bactericides in this class, which makes KASUMIN an excellent product to incorporate into a resistance management program. Effective programs include alternate applications or tank mixtures with other products that have a different mode of action (non-Group 24 bactericide). This will reduce the likelihood of bacteria developing resistance to KASUMIN.

The addition of wetting agents or spreader-sticker agents may enhance the efficacy of KASUMIN.
