Using Diquat in Combination with Endothall Under Turbid Water Conditions to Control Hydrilla

PURPOSE: This small-scale study examined three turbidity levels in the water column to investigate the efficacy of diquat (6,7-dihydrodipyrido[1,2-α:2’,1’-c]pyrazinediium ion) in combination with the dipotassium salt of endothall (7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylic acid) to control hydrilla (Hydrilla verticillata (L.f.) Royle).
