2,4-D sodium salt BiologicalActivity
| Description | 2,4-D sodium salt (Sodium 2,4-dichlorophenoxyacetate) is a selective systemic herbicide for the control of broad-leaved weeds. 2,4-D sodium salt acts as a plant hormone, causing uncontrolled growth in the meristematic tissues. 2,4-D sodium salt inhibits DNA and protein synthesis and thereby prevents normal plant growth and development[1]. |
