General Info

Key Benefits 

  • HEROLD® contains flufenacet, a key active for black-grass control
  • The combination of two a.i.’s from two different groups (diflufenican – Group 12 and flufenacet – Group 15) provides two different modes of action, therefore, managing the risk of herbicide resistance
  • Flexibility of tank mix partners to boost black-grass control and provide additional broad-leaved weed control
