introduction | 2,4-dibromophenoxyacetic acid is a systemic conduction broad-spectrum killing herbicide, mainly by inhibiting the enol acetone-based shikine phosphate synthase in plants, thereby inhibiting the conversion of shikimin to phenylalanine, cool amino acid and tryptophan, and interfering with protein synthesis leading to plant death. |
use | 2,4-dibromophenoxyacetic acid is absorbed through leaves and non-woody stems and conducted to all parts of the plant body, which can control monocotyledonous and dicotyledonous, annual and perennial herbs and shrubs and other more than 40 families of plants. The activity of 2, 4-dibromophenoxyacetic acid to broad-leaved weeds is relatively high, and the activity to gramineous weeds is relatively low, especially to the elderly gramineous weeds. |
