Useful:

• Description: Diquat (DQ) is a bipyridyl herbicide that has been in use since the 1950s. It is employed as a general use herbicide that is fast acting and nonselective. Additionally, on average, 90% of DQ consumption is reported in North America, Europe, Australia, and Japan.
• Uses: DQ is used in a manner similar to paraquat. It is found predominantly as a mixture with paraquat, sold as Weedol and Pathclear. The most widely used formulation of DQ alone, Reglone, is an aqueous solution containing 200 g l-1 DQ dibromide. Besides the use as a general weed control agent on noncrop land, DQ is used as a preharvest desiccant on crops such as cotton, flax, and alfalfa. Additionally, almost one-third of all DQ sold is used to control emergent and subemergent aquatic weeds. Diquat Dibromide is a herbicidal desiccant. Nonselective contact herbicide used to control broad-leaved weeds in fruit and vegetable crops.
