Biological activity | 2,4-D sodium salt (Sodium 2,4-dichlorophenoxyacetate) is a selective herbicide for broadleaf weed control. 2,4-D sodium salt, as a plant hormone, causes uncontrolled growth in meristem. 2,4-D sodium salt inhibits DNA and protein synthesis, thereby preventing the normal growth and development of plants. |
use | high concentration can weed, low concentration can effectively prevent falling flowers and fruits, and is also a good preservative and fresh preservation product for fruits and vegetables |
