Diquat Aquatic Herbicide



Active Ingredient: Diquat Dibromide 37.3%

Diquat aquatic herbicide is a fast-acting, non-selective herbicide that controls floating, submerged and marginal aquatic weeds, even in sensitive aquatic environments. In addition to this diquat is also ideal for non-selective weed control and burn-down in turf and landscapes.

Diquat Herbicide is used to control aquatic weeds in public waters such as ponds, lakes, reservoirs, marshes, bayous, drainage ditches, canals, streams, rivers, and other slow-moving or quiescent bodies of water. 

  • It can be used along the edges and non-flooded areas of ponds, lakes, drainage ditches and canals.
  • Once applied, it diffuses rapidly through the cuticle and then throughout the leaf tissue of the weed. The first effects can be seen within an hour.
  • Complete control of floating vegetation occurs within one to five days, while submerged weeds require approximately five to 15 days for control.
  • Highly active, non-selective
  • Broadest spectrum aquatic herbicide available
  • Low use rates
  • Manages weed problems in aquatic, grounds maintenance and landscaping areas
