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.
