Managing weeds around drains, irrigation channels, dams and waterways requires the right chemistry and approved products. Not all herbicides are suitable near water. Notman Pasture Seeds helps farmers, contractors and land managers choose practical aquatic weed control options for channels, wet areas, riparian zones and non-crop situations.
Many aquatic weed programs achieve best results by combining knockdown + residual + adjuvant technology depending on weed pressure and irrigation timing.
SOLUTIONS FOR AQUATIC AREAS
Need rapid brownout? → Diquat 200
Need root kill on perennial weeds? → Glyphosate Green 360 or Amitrole 250
Need residual weed suppression in channels? → Flumioxazin 500 WG or Diuron 900 WG
Need improved herbicide uptake? → Add FLX700 Aquatic Adjuvant
KEY AQUATIC WEED HERBICIDES & WHAT THEY TARGET
- Diquat 200: Fast knockdown herbicide for rapid clean-up of Duckweed, Azolla, Salvinia, Water Hyacinth, Water Lettuce and pond weeds. Best where quick brownout is needed.
- Amitrole 250 Systemic herbicide targeting difficult perennial weeds including Cumbungi, Phragmites, Nutgrass and Water Couch. Useful where long-term suppression is needed.
- Diuron 900 Residual herbicide helping suppress grasses and broadleaf weeds in drains and irrigation areas. Commonly partnered with knockdown herbicides for longer weed control.
- Glyphosate Green 360: Aquatically approved systemic herbicide providing root kill on annual and perennial weeds, reducing regrowth in channels and waterways.
- Flumioxazin 500WG: Residual Group G herbicide improving knockdown and suppressing new weeds including Fleabane, Feathertop Rhodes, Summer Grass and Pigweed. Strong fit in empty channels.
- FLX700 Aquatic Adjuvant: Aquatically approved surfactant, penetrant and acidifier designed to improve performance of Glyphosate, Diquat, Amitrole and Flumioxazin.
Where these products fit
Good fit for:
- irrigation drains and channels
- dam edges
- riparian strips
- wet drains
- farm laneways near water
- council and contractor vegetation programs
- sensitive non-crop areas
Why aquatic-approved herbicides matter
Not all glyphosate, knockdown or broadleaf herbicides are suitable near waterways. Standard formulations may contain surfactants or label restrictions that make them unsuitable for aquatic situations. The correct product choice helps reduce risk while still achieving reliable vegetation control.
