| DIQUAT DIBROMIDE Chemical Properties |
| RIDADR | 2781 | | HazardClass | 6.1(a) | | PackingGroup | II | | Toxicity | A contact
herbicide used as a defoliant. Its oral LD50 in rats is 231 mg/
kg and in mice is 125 mg/kg. It is a convulsant, and its herbicidal
and toxic actions may be mediated by free radical reactions
similar to those of paraquat. Unlike paraquat, diquat is
not toxic to, and not retained in, the lung. Acute diquat poisoning
causes acute hyperexcitability leading to convulsions and
distension of the gastrointestinal tract. |
| DIQUAT DIBROMIDE Usage And Synthesis |
| Uses | diquat may be applied as preplanting
treatments for many agronomic crops to eliminate
weeds at or before planting. In addition, these herbicides
may be used in established perennial crops such
as alfalfa, mint, and rhubarb during the dormant cycle.
Similarly, their use in vineyards, orchards, and coffee and
rubber plantations, at times of crop dormancy or using
directed sprays so that only the weed is contacted, are
useful for total weed control measures. Diquat is also used
extensively as an aquatic herbicide to control algae and
submerged and floating aquatic weeds. | | Preparation | Diquat is synthesized by reaction of 2,2 -bipridyl with
di-n-propyl amine (1,9). |
