CAS: 37514-30-0
Diquat dibromide (CAS: 37514-30-0) is a non-selective, contact herbicide and plant desiccant belonging to the bipyridylium class. It acts rapidly upon contact with green plant tissue, causing cell membrane disruption and desiccation. It is primarily used for controlling a wide range of annual and perennial broadleaf weeds and grasses, particularly in aquatic environments and as a harvest aid.
Used as an herbicide for the control of broadleaf weeds and grasses in various settings. Employed as an aquatic herbicide to manage submerged and emergent weeds in ponds, lakes, drainage ditches, and irrigation canals. Applied as a desiccant or defoliant for pre-harvest treatment of crops such as potatoes, soybeans, cotton, and oilseed rape to facilitate harvesting. Also used for weed control in non-crop areas, industrial sites, and rights-of-way.
Agricultural applications include pre-harvest desiccation and weed control in specific crops. Widely used for aquatic weed management. Non-agricultural applications involve vegetation management in industrial areas, along railways, roadsides, and in landscape maintenance. Can also be used for pre-plant weed control in minimum tillage systems.
Diquat dibromide is highly toxic if ingested, potentially causing severe gastrointestinal distress, kidney and liver damage, central nervous system effects, and respiratory failure. It is irritating to the skin, eyes, and respiratory tract, and may cause skin sensitization. It is toxic to aquatic organisms and should be handled with appropriate personal protective equipment (PPE), including gloves, eye protection, and protective clothing. Proper storage in a cool, well-ventilated area, away from food and feed, is crucial. Disposal must comply with local, state, and federal regulations.
