Haloxyfop-P-methyl(D)

Flupyrifos is colorless crystal, melting point 55~57℃, vapor pressure 0.80mPa(25℃), KowlgP=4.07.Henry's constant 3.23×10-2Pa-m3/mol(calculated value), solubility in water 9.3mg/L(25℃); solubility in other solvents(kg/kg, 20℃). Acetonitrile 4.0, acetone 3.5, dichloromethane 3.0, xylene 1.27.

Flumioxazin can be used for annual grass weeds such as barnyard grass, dogweed, horseweed, wild oats, oxalis, wild millet, golden seed, early morning glory, dry bird's-bread, barley, look at the maiden, ryegrass and so on. Perennial grasses   Undergraduate weeds such as creeping iceplant, weedy wheatgrass, false sorghum, reed, and dogbane. The annual and perennial grass weeds in the early stage of seedling and spike have good prevention and control effects, but are not effective on broadleaf grass and sedge.

Haloxyfop-P-Methyl (D) is a selective, post-emergence herbicide primarily used to control annual and perennial grass weeds in broadleaf crops. As a derivative of the aryloxyphenoxypropionate (AOPP) group of herbicides, it inhibits fatty acid synthesis in target plants, disrupting their growth and leading to effective weed control.

Key Features

1. Selective Action: Targets grass weeds without harming broadleaf crops.

2. Post-Emergence Control: Effective on actively growing weeds.

3. Systemic Activity: Moves through the plant to ensure complete eradication, including roots.

4. Wide Crop Compatibility: Suitable for use in crops such as soybeans, peanuts, and cotton.

Applications

Crops Treated

• Soybeans

• Cotton

• Peanuts

• Sugarcane

• Vegetables

Weeds Controlled

• Annual Grasses: Wild Oat (Avena fatua), Barnyardgrass (Echinochloa crus-galli), Green Foxtail (Setaria viridis).

• Perennial Grasses: Johnson Grass (Sorghum halepense), Couch Grass (Elymus repens), Bermuda Grass (Cynodon dactylon).

Mechanism of Action

Haloxyfop-P-Methyl (D) inhibits acetyl-CoA carboxylase (ACCase), an enzyme critical for fatty acid synthesis in grasses. Without fatty acid production, the plant cannot build cell membranes, leading to the cessation of growth and eventual plant death.

Advantages

1. Precision Control: Highly effective against grass weeds while sparing broadleaf crops.

2. Systemic Effectiveness: Ensures complete weed elimination, including underground rhizomes.

3. Flexibility: Can be applied across a range of crops and weed growth stages.

4. Ease of Application: Compatible with common spray equipment and tank mixes.

Safety and Environmental Considerations

Handling and Storage

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

• Store in a cool, dry, and well-ventilated area away from food, water, and animal feed.

Environmental Impact

• Aquatic Toxicity: Avoid contamination of water bodies to protect aquatic organisms.

• Non-Target Effects: Prevent drift to protect non-target plants and crops.

Regulatory Compliance

• Follow local regulations and label directions for safe application.

Limitations

1. Target-Specific: Ineffective against broadleaf weeds or non-grass species.

2. Resistance Risks: Prolonged use may result in herbicide-resistant weed populations.

3. Rainfastness: Requires a minimum drying period post-application for optimal effectiveness.

Conclusion

Haloxyfop-P-Methyl (D) is a reliable solution for managing grass weeds in broadleaf crops. Its systemic action, selective control, and ease of application make it a valuable tool in modern weed management strategies. Proper usage and adherence to resistance management guidelines are essential for sustainable and effective weed control.
