Dewberry
Use metsulfuron 60 DF or Cimarron Plus at 1 oz/A plus 0.25% nonionic surfactant. Apply in May or June while blackberry and dewberry are actively growing. Remedy Ultra at 3 pt/A applied during or after bloom has been effective for blackberry and dewberry. Surmount at 2 qt/A is another option. Apply Surmount after fruit drop. Do not mow during the year of application. Regardless of treatment choice, plan on making a follow-up treatment the next year to control escapes.
