Control of sugar beet, sod, ryegrass and other weeds in pastures.

Ethofumesate is a selective herbicide primarily used for pre-emergence and early post-emergence control of annual grasses and broadleaf weeds. It is particularly effective in crops like sugar beets, turfgrass, onions, and carrots. Its long-lasting residual activity provides extended weed suppression, reducing competition and supporting healthy crop growth.

Key Features

1. Selective Action: Targets weeds without harming crops such as sugar beets and turfgrass.

2. Versatility: Effective for both pre-emergence and early post-emergence applications.

3. Residual Control: Offers extended weed suppression by remaining active in the soil.

4. Broad Weed Spectrum: Controls a variety of annual grasses and broadleaf weeds.

Applications

Crops Treated

• Sugar Beets

• Turfgrass

• Carrots

Weeds Controlled

• Annual Grasses:

  • Barnyard Grass (Echinochloa crus-galli)

  • Foxtails (Setaria spp.)

  • Crabgrass (Digitaria spp.)

  • Common Chickweed (Stellaria media)

  
  

Mechanism of Action

Ethofumesate inhibits lipid synthesis in susceptible plants, disrupting cell membrane formation and energy production. This prevents the germination and growth of weed seedlings. It is absorbed through both the roots and shoots of weeds, making it effective for pre-emergence and early post-emergence applications.

Advantages

1. Extended Residual Control: Reduces the need for repeated applications.

2. Crop Safety: Highly selective for key crops like sugar beets and turfgrass.

3. Effective on Young Weeds: Provides excellent control when weeds are in their early growth stages.

4. Versatile Application: Suitable for both pre-emergence and early post-emergence use.

Safety and Environmental Considerations

Handling and Storage

• Use appropriate personal protective equipment (PPE) during handling and application.

• Store in a cool, dry place away from food, water, and animal feed.

Environmental Impact

• Aquatic Safety: Avoid runoff into water bodies to protect aquatic ecosystems.

• Soil Persistence: Moderate soil activity; follow label instructions to prevent carryover effects.

• Non-Target Plants: Avoid drift to neighboring crops or ornamental plants.

Regulatory Compliance

• Always adhere to local regulations and label guidelines.

Limitations

1. Resistance Management: Overuse may lead to the development of resistant weed populations.

2. Application Timing: Most effective when applied at the correct stage of weed development.

3. Limited Grass Control: Less effective on mature grasses or perennial species.

Conclusion

Ethofumesate is a reliable herbicide for managing annual grasses and broadleaf weeds in crops like sugar beets, turfgrass, and onions. Its residual activity and versatility make it an essential tool in integrated weed management programs. Proper application timing and adherence to resistance management strategies are key to maximizing its effectiveness.
