Atrazine 900 WG 10kg Herbicide 900g/kg

Atrazine 900 WG is a Residual Herbicide for the control of certain Broadleaf Weeds in Maize, Sweetcorn, Linseed and established Lucerne.
Active Ingredient:
900 g/L Atrazine in the form of a water Dispersible Granule.
What It Controls:
The label/product information says it Controls:
- Broadleaf Weeds.
- Some Annual Grasses.
Typical Target Weeds Include:
- Fathen.
- Redroot.
- Black Nightshade.
- Chickweed.
- Summer Grass (suppression/control depending on timing).
Atrazine 900 WG (Is Especially Valued For).
- Long residual Weed suppression.
- Cost-effective Maize Weed Control.
Where You Can Use It:
Registered Uses Include:
- Maize.
- Sweetcorn.
- Linseed.
- Established Lucerne.
Not Suitable For:
- Lawns.
- Gardens.
- General Pasture spraying.
How It Works:
Atrazine 900 WG is absorbed mainly through the roots (and to a lesser extent through the foliage) of susceptible Weeds. It works by inhibiting photosynthesis, causing emerging Weeds to stop growing and eventually die.
Pre-emergence vs Post-emergence Use:
Atrazine 900 WG Can Work:
- Pre-emergence → before Weeds emerge.
- Post-emergence → on small young Weeds.
Best Performance:
- Small Weeds.
- Moist soil.
- Good spray coverage.
Residual Activity: (VERY important).
Atrazine 900 WG has soil residual activity, that means It continues controlling Weeds after Spraying.
Can persist in Soil for Weeks/Months depending on:
- Soil Type.
- Rainfall.
- Temperature.
- This is one reason Maize Growers still use it heavily.
But Residual Activity Also Means:
- Crop rotation restrictions.
- Potential damage to sensitive follow-on Crops.
Application Basics:
Typical Use Pattern:
- Boom Spray application water rates commonly around 100–300 L/ha.
Use Rates Vary Depending On:
- Crop.
- Weed Pressure.
- Timing.
- Tank Mixes.
Atrazine 900 WG (Is Often Mixed With).
- Acetochlor.
- Dicamba.
- Mesotrione.
- Other Maize Herbicides.
Timing: (CRITICAL).
Best Results:
- Early Weed growth.
- Moist soil conditions.
Avoid:
- Large established Weeds.
- Dry soil.
- Drought-stressed Weeds.
- Atrazine 900 WG is much weaker on mature Weeds.
Rainfall & Activation:
- Moisture improves performance significantly.
- Rain after application helps activate soil residual control.
- Dry conditions reduce effectiveness.
Spray Drift & Sensitive Plants:
Atrazine 900 WG Drift Can Damage:
- Vegetables.
- Ornamentals.
- Sensitive Crops.
- Also Avoid spraying near waterways.
Safety & Hazards: (According to the SDS Label).
- Harmful if swallowed.
- May cause allergic skin reactions.
- May damage organs with repeated exposure.
- Very toxic to aquatic life.
- Toxic to soil organisms and wildlife.
PPE Required:
- Gloves.
- Protective Clothing.
- Avoid breathing dust/spray mist.
Environmental Concerns:
Atrazine 900 WG Is Widely Known For:
- Persistence in soil/water.
- Water contamination concerns.
The label/SDS: (STRONGLY Warns).
- Prevent runoff.
- Avoid direct application to water.
Resistance Management:
- Group 5 Herbicide.
Repeated Use Alone Can Lead To:
- Atrazine-resistant Weeds.
- This is now a real issue in some Maize-growing regions worldwide.
Key Mistakes To Avoid:
- Applying to large Weeds.
- Atrazine 900 WG works best early.
- No rainfall after spraying.
- Residual performance drops.
- Ignoring Crop rotation.
- Residual carryover can injure later crops.
- Spraying near waterways.
- High aquatic toxicity risk.
- Repeated solo use.
- Can select resistant Weeds.
Bottom Line:
Atrazine 900 WG is:
- A strong residual Maize Herbicide.
Best For:
- Broadleaf Weed Control.
- Early-season suppressionv Valuable Because:
- Cheap.
- Reliable.
- Long-lasting.
- But It has Environmental Persistence and requires careful timing and stewardship.
Caution:
Use strictly according to label directions.
