Fluroxypyr-meptyl 288g/L EC

Fluroxypyr-meptyl 288g/L EC is a synthetic auxin herbicide formulated as an emulsifiable concentrate (EC). It targets broadleaf weeds through hormonal disruption, causing uncontrolled growth and eventual plant death. Known for its high efficacy against resistant weeds and crop safety in cereals, it is widely used in integrated weed management systems

Key Technical Specifications

CAS No.	81406-37-3
Chemical Class	Pyridine carboxylic acid (Synthetic plant hormone)
Formulation Type	Emulsifiable Concentrate (EC)
Mode of Action	Auxin mimic → disrupts cell division and vascular tissue development
Target Weeds	Broadleaves: Galium aparine (cleavers), Cirsium arvense (creeping thistle), Convolvulus arvensis (bindweed)
Registered Crops	Wheat, barley, corn, pastures

Application Guidelines

Dosage & Timing:

Crop	Target Weeds	Dosage	Application Timing
Wheat	Cleavers, thistles	150–200 mL/ha	Post-emergence (weed 2–4 leaf stage)
Corn	Bindweed, nightshade	200–250 mL/ha	Early growth stage (crop 3–5 leaves)
Pastures	Broadleaf invasives	100–150 mL/ha	Pre-flowering of weeds

Critical Practices:

Spray Volume: 300–400 L/ha for uniform coverage.
Rainfastness: Requires ≥1 hour dry period post-application.
Avoid Drift: Use low-pressure nozzles to protect adjacent broadleaf crops.

Safety & Environmental Profile

Parameter	Data	Regulatory Notes
Toxicity Class	Low mammalian toxicity (WHO Class U)	Safe with standard PPE
Ecotoxicity	Highly toxic to aquatic life	50m buffer from water bodies
Soil Half-life	DT50: 10–14 days	Low leaching risk
Re-entry Period	12 hours	—

⚠️ Precautions:

Incompatible with alkaline additives (pH >7.0).
Do not apply during cereal flowering to avoid pollen damage.

Advantages & Limitations

Advantages:
