Desiccation of alfalfa for seed production with diquat and glufosinate
, 1996 Recommendations for desiccation of alfalfa do not clearly define the stage at which desiccants should be applied. To obtain this information, diquat and glufosinate were applied to alfalfa (Medicago sativa L) from 1991 to 1994 at various stages of ...

Effect of diquat on the distribution of iron in rat liver
, 1988 Diquat toxicity is proposed to be mediated through the generation of active oxygen species; however, the exact role of active oxygen in toxicity is not known. The generation of damaging oxygen radicals requires transition metals such as iron.

Complexation of Diquat by a bisparaphenylene-34-crown-10 derivative
, 1987 X-Ray structural investigations of a bisparaphenylene-34-crown-10 derivative (BPP34C10) and its 1:1:1 complex with [Diquat][PF6] 2 and H2O reveal that, of two crystallographically independent conformations (I and II) both supporting large molecular ...
