Dicamba

Dicamba (CAS 1918-00-9), also known as MDBA, is a selective benzoic acid herbicide used in commercial agriculture to control broadleaf weeds and woody plants.

Where is Dicamba used?

• Cereal grain crops such as wheat, corn and sorghum: suppresses persistent weeds
• Dicamba-tolerant soybean and cotton programs: active ingredient in pre-emergent formulations for genetically modified crop systems
• Turf management and non-crop land: clears rights-of-way, pastures and rangeland of invasive broadleaf vegetation
• Combination herbicide products: incorporated alongside active ingredients such as 2,4-D to broaden weed control spectrum
• It functions by mimicking natural plant growth hormones, causing uncontrolled growth in susceptible species while leaving established grasses largely unaffected.

Good to know: Most commonly the dimethylamine and diglycolamine salt forms are used, which offer improved volatility profiles for field use. Particularly effective against kochia, bindweed and thistle that resist other herbicide classes.

Commercial specifications
