Mesosulfuron-methyl 30g/L OD Herbicide

Mesosulfuron-methyl 30g/L OD is an oil-based dispersion (OD) herbicide formulated for selective control of annual grass and broadleaf weeds in wheat fields. Its advanced oil dispersion technology enhances foliar adhesion and rainfastness, providing reliable post-emergence weed management in both spring and winter wheat systems

2. Technical Specifications

Parameter	Details
Active Ingredient	Mesosulfuron-methyl 30g/L (3% w/w)
Formulation Type	Oil Dispersion (OD)
Chemical Class	Sulfonylurea (ALS inhibitor, IRAC Group 2)
Target Weeds	Annual grasses + broadleaves (e.g., chickweed/Cerastium)
Registered Crops	Spring wheat, Winter wheat

3. Application Guidelines

Dosage & Method:

Crop	Target Weeds	Dosage	Application
Spring wheat	Annual grasses, Chickweed, Broadleaves	20–35 mL/mu*	Foliar spray
Winter wheat	Annual grasses, Chickweed, Broadleaves	20–35 mL/mu*	Foliar spray
*1 mu ≈ 667 m²; Spray volume: 300–400 L/ha 1.

Critical Timing:

Apply at weed early-growth stage (2–4 leaves).
Avoid spraying during wheat jointing or flowering stages.

4. Performance Features

Weed Spectrum: Controls >20 species, including:
- Grasses: Avena fatua (wild oats), Alopecurus aequalis (shortawn foxtail).
- Broadleaves: Cerastium glomeratum (chickweed), Stellaria media (common chickweed) 1.
Rainfastness: Oil carrier ensures adhesion after 1-hour drying.
Crop Safety: Low phytotoxicity risk when applied ≤35 mL/mu.

5. Safety & Compliance

Parameter	Specification
PHI (Pre-Harvest Interval)	Not specified (follow local regulations)
Re-entry Interval	24 hours
Ecotoxicity	Toxic to aquatic life – maintain 50m buffer from water bodies
Storage	Store in cool (5–30°C), dark place; avoid freezing

6. Resistance Management

Rotate with non-ALS inhibitors (e.g., auxin mimics like 2,4-D or ACCase inhibitors like fenoxaprop).
Maximum applications: 1 per season to delay resistance development.
