- Use: Selective systemic herbicide used to control broadleaf weeds in cereals, corn, pastures, lawns, and turf. One of the oldest and most widely used herbicides globally. Key component in herbicide-tolerant (e.g., Enlist) cropping systems.
- Conclusion: 2,4-D remains a vital, cost-effective tool for broadleaf weed control in agriculture and beyond, but concerns over off-target movement (volatility, drift) causing damage to sensitive crops and plants, potential contamination of water, and ongoing debate about its health effects (especially when contaminated with dioxins historically) necessitate careful application practices and stewardship.
