HERBICIDE DEFENDA SHERIFF

Mechanism of action

By its mode of action, tribenuron-methyl belongs to the amino acid synthesis inhibitors. Penetrating through the leaves, stems and roots, it is transported to the growing points, where it blocks the production of essential amino acids and cell division. Within 2-3 hours after treatment, sensitive weed plants stop growing and developing, and cease absorbing water and mineral nutrients from the soil and competing with crop plants. Visual signs of the product's action are observed after 5-8 days, appearing as browning and death of the weeds. Young weeds die 2-3 days earlier than weeds at later stages of development.
