Bifenazate 480g/L SC

Active Ingredient: Bifenazate

CAS Number: 149877-41-8

Molecular Formula: C₁₇H₂₀N₂O₃

Classification: Non-systemic contact miticide (selective for mites).

Primary Use: Controls spider mites in fruits, vegetables, ornamentals, and turfgrass.

Bifenazate is formulated for easy application, typically as a spray. Below are the recommended dosages for different crops:

Formulation Plants Pest Dosage Application Method
48% SC Tomatoes Red spider mites 40 ml/100 liters water Spray
48% SC Apples Red spider & two-spotted spider 35 ml/100 liters water Spray
48% SC Cucurbits Red spider & two-spotted spider 40 ml/100 liters water Spray
48% SC Citrus fruits Red spider & two-spotted spider 35 ml/100 liters water Spray

Mode of Action

  • Mechanism: Disrupts mitochondrial electron transport chain (Complex III) in mites → inhibits energy production → paralysis and death
  • Contact Activity: Requires direct contact with mites; effective against all life stages (eggs, larvae, nymphs, adults)
  • Speed of Action:
    • Adult mites: Rapid knockdown within 48–72 hours
    • Eggs: Mortality within 1–2 weeks of application

Target Pests & Crops

Crops Target Pests Application Method Key Notes
Citrus Red spider mites, two-spotted mites Foliar spray Ensure coverage of leaf undersides
Apples European red mites, two-spotted mites Foliar spray Apply at early infestation stages
Tomatoes Red spider mites Foliar spray Reapply every 14 days if needed
Cucurbits Two-spotted mites Foliar spray Avoid spraying during flowering
Ornamentals Broad mites, rust mites Foliar spray Safe for most ornamental species
Turfgrass Spider mites, red mites Spray or granular application Target early morning/late evening for best absorption

Formulations & Dosage

  • Single-Active Formulations:
    • SC (Suspension Concentrate): 240 g/L, 480 g/L (e.g., 48% SC for foliar use)
    • WP (Wettable Powder): 50% WP (suitable for small-scale applications)
    • WDG (Water-Dispersible Granules): 50% WDG
  • Combination Formulations:
    • Bifenazate + Cyflumetofen (200g/L + 200g/L SC): Enhanced broad-spectrum control
    • Bifenazate + Etoxazole (30% + 10% SC): Targets both mites and eggs
  • Dosage Range:
    • Foliar spray: 0.5–1.0 L/ha (48% SC: 35–40 ml/100 L water for fruits/vegetables)
    • Seed treatment: Not recommended (non-systemic)

Key Features & Benefits

  1. Selective Action:
    • Low toxicity to beneficial insects (e.g., ladybugs, predatory mites, bees)
    • Ideal for integrated pest management (IPM) programs
  2. Broad-Spectrum Efficacy:
    • Controls resistant mite strains (e.g., two-spotted mites resistant to organophosphates)
    • Effective against TetranychusPanonychus, and Eutetranychus species
  3. Long Residual Activity:
    • Up to 14 days of protection reduces application frequency
  4. Crop Safety:
    • No reported phytotoxicity when used at recommended rates
    • Safe for use in organic systems (check local regulations)

Application Guidelines

  • Timing:
    • Early infestation (when mite populations are low to moderate)
    • Avoid applying during flowering to protect pollinators
  • Method:
    • Use high-pressure sprayers to ensure coverage of leaf undersides
    • Mix thoroughly with water (100–200 L/ha) for uniform distribution
  • Environmental Considerations:
    • Avoid spraying in windy conditions to prevent drift
    • Do not apply near water bodies (toxic to fish and algae)

Safety & Storage

  • Personal Protection:
    • Wear gloves, goggles, and long-sleeved clothing
    • Avoid inhalation or skin contact; wash hands after application
  • Storage:
    • Cool (2–8°C), dry, and dark environment
    • Store in original sealed containers; keep away from food/feed
    • Shelf life: 2–3 years when properly stored

Packaging Options

  • Small Scale: 500 ml, 1L, 5L SC bottles (for farmers and gardeners)
  • Bulk: 25kg WP/WDG bags, 200L drums, 1000L IBCs (for commercial agriculture)
  • Custom: OEM/ODM labeling for brand customization

Technical Specifications

  • IRAC Group: 23 (unique mode of action; no cross-resistance with other miticide groups)
  • Residue Limits: Complies with EU MRLs (e.g., 0.02 mg/kg for citrus) and USDA standards
  • Degradation: Photodegradable in sunlight; half-life in soil: 7–14 days
