Description
Diuron 900 WG is a residual herbicide used for controlling a range of annual grasses and broadleaf weeds in lucerne, legume-based pastures, knockdown programs and some aquatic or irrigation situations. It provides longer-lasting weed suppression by remaining active in the soil, helping reduce germination of new weeds after application.
Diuron is commonly partnered with glyphosate or paraquat to strengthen paddock knockdowns and extend weed control beyond the initial burn-down.
Why farmers use it
- Long residual activity for extended weed suppression
- Useful knockdown partner with glyphosate and paraquat
- Controls emerging broadleaf and grass weeds
- Helps keep paddocks cleaner for longer
- Useful around drains, irrigation channels and aquatic areas where registrations permit
- Strong fit in lucerne and pasture weed programs
Useful in aquatic and irrigation areas
Diuron is also commonly used in drains, channels, irrigation infrastructure and non-crop areas for longer-term weed suppression where weed pressure restricts water movement or maintenance access.
Residual activity can help:
- Keep drains cleaner for longer
- Reduce repeat weed germination
- Lower maintenance frequency in irrigation systems
- Improve water flow and access around channels
Always check label directions regarding aquatic registrations, buffer zones and water movement before use.
