Applications

Fomesafen is used as an herbicide for preventing and clearing the broad-leaf weeds post emergent of soybean.

Quizalofop-p-ethyl is is a selective, postemergence phenoxy herbicide. It is used to control annual and perennial grass weeds in potatoes, soybeans, sugar beets, peanuts, vegetables, cotton and flax, as well as other crops.

This herbicide mixture combines Fomesafen (Group 14, PPO inhibitor) and Quizalofop-p-ethyl (Group 1, ACCase inhibitor) to provide broad-spectrum weed control in compatible crops. It targets both broadleaf weeds (via residual and post-emergence activity) and grasses (post-emergence systemic control).

Target Weeds
Broadleaf Weeds (controlled by Fomesafen):
Pigweeds (Amaranthus spp.), morningglories (Ipomoea spp.), cocklebur (Xanthium spp.), common ragweed (Ambrosia spp.), and velvetleaf (Abutilon theophrasti).
Grasses (controlled by Quizalofop-p-ethyl):
Crabgrass (Digitaria spp.), foxtails (Setaria spp.), barnyardgrass (Echinochloa spp.), and Johnsongrass (Sorghum halepense).

Key Uses
Pre-Emergence Residual Control: Fomesafen inhibits weed seedling emergence by disrupting cell membranes.
Early Post-Emergence Control: Fomesafen targets small, actively growing broadleaf weeds (≤ 4 inches tall).
Selective Grass Control: Quizalofop-p-ethyl selectively kills grass weeds in broadleaf crops.

Application Details

Timing:

Apply pre-emergence or early post-emergence (broadleaf weeds ≤ 4 inches tall; grasses at 2-6 leaf stage).
Avoid application during crop stress (drought, heat, or waterlogged soils).
Supplemental rainfall (≥10 mm) within 7 days enhances activation.

Rates:

Typical rates (varies by crop and label):
Fomesafen: 100-200 g ai/ha (1-2 L/ha of 10% EW).
Quizalofop-p-ethyl: 50-100 g ai/ha (1-2 L/ha of 5% EW).
Adjust based on weed pressure and soil type.

Method:

Broadcast or directed spray using ground equipment.
Add a non-ionic surfactant (0.25-0.5% v/v) or crop oil concentrate (1% v/v) to improve coverage and efficacy.

Tank Mixing:

Order: Add Quizalofop-p-ethyl first, then Fomesafen (follow label instructions).
Avoid mixing with organophosphate insecticides or high pH adjuvants (risk of reduced efficacy).
Ensure thorough agitation during mixing.

Environmental Considerations
Soil Persistence: Fomesafen persists in clay soils, requiring a 9-12-month rotational restriction for legumes or sensitive crops.
Leaching Risk: Avoid application on sandy soils with heavy rainfall to prevent groundwater contamination.
Non-Target Plants: Quizalofop is non-selective to grasses; avoid drift to desirable legumes or broadleaf plants.

Safety Precautions
PPE: Wear gloves, goggles, long sleeves, and a respirator during handling.
Toxicity: Fomesafen may irritate eyes/skin; Quizalofop is moderately toxic if inhaled.
Aquatic Safety: Do not apply near water bodies (Quizalofop is toxic to aquatic organisms).

Resistance Management
Modes of Action:
Fomesafen (Group 14): Inhibits PPO enzymes in broadleaf weeds.
Quizalofop-p-ethyl (Group 1): Blocks ACCase in grasses.
Rotate with herbicides of different groups (e.g., Group 27 or 4) to delay weed resistance.

Registered Crops
Soybeans: Most common (tolerant to both actives).
Peanuts: Check regional labels for compatibility.
Other Crops: May include sunflowers or cotton if approved.

Additional Tips
Adjuvants: Use ammonium sulfate (AMS) in hard water to enhance glyphosate-like herbicide efficacy (if applicable).
Harvest Intervals:
Soybeans: Typically 45-60 days post-application.
Peanuts: Follow label for fomesafen (often 30-45 days).
Rainfastness: Wait 4-6 hours post-application before rain.

Note: Efficacy depends on proper application timing, weed species, and environmental conditions. Always confirm rates and compatibility with local agricultural guidelines or the product label.
