Diquat dibromide

Diquat dibromide (CAS 85-00-7), also known as Diquat and marketed under the trade name Aquacide, is a fast-acting contact herbicide used in agricultural and aquatic weed management.

Where is Diquat dibromide used?

• Arable farming: pre-harvest desiccant on potato, oilseed rape and legume crops
• Potato storage: suppresses haulm growth and reduces disease pressure before mechanical harvesting
• Aquatic weed control: Aquacide formulations clear irrigation channels, reservoirs and recreational waterways of submerged and emergent vegetation
• Formulators incorporate it into broad-spectrum herbicide blends targeting annual and perennial weeds for non-crop land management and industrial site maintenance
• It disrupts plant cell membranes on contact, delivering rapid desiccation without soil persistence.

Commercial specifications

• Concentrated aqueous solution, typically 200 g/L active ingredient
• Bulk supply in intermediate bulk containers (IBCs) and drums
