Applications

 

The herbicide combination of Mesosulfuron-methyl + Iodosulfuron-methyl sodium + Mefenpyr-diethyl is a post-emergence ALS-inhibiting herbicide used primarily in wheat and barley for controlling grass and broadleaf weeds, including resistant biotypes. Below is a detailed breakdown of its application, uses, and key considerations.

 

1. Target Crops

• Winter wheat

• Spring wheat

• Barley (some formulations may also include triticale and rye)

 

2. Target Weeds (Effective Against)

Grass Weeds (Especially ALS-resistant populations)

• Blackgrass (Alopecurus myosuroides)

• Wild oats (Avena fatua)

• Italian ryegrass (Lolium multiflorum)

• Brome species (Bromus spp.)

Broadleaf Weeds

• Chickweed (Stellaria media)

• Pansy (Viola arvensis)

• Mayweed (Matricaria spp.)

• Cleavers (Galium aparine)

 

3. Mode of Action

• Mesosulfuron-methyl & Iodosulfuron-methyl sodium: Both are ALS (acetolactate synthase) inhibitors, disrupting branched-chain amino acid (valine, leucine, isoleucine) synthesis in weeds.

• Mefenpyr-diethyl: A safener that enhances crop tolerance by accelerating herbicide detoxification in wheat/barley.

 

4. Application Guidelines

Parameter	Recommendation
Application Timing	Post-emergence, when weeds are small (2-4 leaves for grasses, rosette stage for broadleaves).
Dosage	Typically 12-15 g/ha mesosulfuron + 1-2 g/ha iodosulfuron + 3-6 g/ha mefenpyr-diethyl (varies by formulation).
Water Volume	100-200 L/ha (ensure full coverage).
Adjuvants	Often requires non-ionic surfactant (NIS) or methylated seed oil (MSO) for efficacy.
Rainfastness	1-2 hours (check label).

 

5. Advantages

 Broad-spectrum control of key resistant grasses and broadleaves.
 Low use rates (reducing environmental impact).
 Crop safety due to mefenpyr-diethyl safener.

 

6. Limitations & Precautions

• Not effective on all weeds (e.g., some Polygonum spp., established perennials).

• Resistance risk: Overuse may select for ALS-resistant weeds (rotate with non-ALS herbicides).

• Crop restrictions: Only approved for certain cereals (check local regulations).

• Temperature sensitivity: Avoid application under stress (drought, extreme cold/heat).

 

7. Example Trade Names

• Atlantis® WG (Bayer) - Mesosulfuron + Iodosulfuron + Mefenpyr.

• Othello® (Syngenta) - Similar formulation with adjuvants.

 

8. Best Practices

• Apply at consistent spray pressure (avoid drift).

• Rotate with herbicides of different MoA (e.g., ACCase inhibitors like pinoxaden) to delay resistance.

• Monitor weeds for reduced sensitivity over time.
