Quizalofop-P-Ethyl 108g/L EC

Quizalofop-P-Ethyl is a refined, high-performance post-emergence herbicide designed to eliminate annual and perennial grassy weeds in a wide range of broadleaf crops. This advanced formulation features enhanced purity through the removal of the non-active optical isomer, offering superior systemic weed control and increased crop safety.

Why Choose Quizalofop-P-Ethyl?

  • Selective Action – Controls grassy weeds without harming broadleaf crops.

  • Fast-Acting Formula – Rapid absorption and translocation ensure visible weed damage within days.

  • High Purity – Improved version of Quizalofop with better efficacy and stability.

  • Flexible Application – Suitable for various crop systems and environmental conditions.

  • Customizable for Distributors – Available in bulk with tailored packaging, formulation, and labeling.

Mode of Action

Quizalofop-P-Ethyl works by inhibiting Acetyl-CoA Carboxylase (ACCase)—an enzyme vital for fatty acid synthesis in grassy weeds. After foliar absorption, the active ingredient is systemically translocated to the shoot tips and meristematic tissues, where it disrupts lipid metabolism, causing irreversible damage and eventual plant death.

Target Weeds

Effective against common grass weeds including:

  • Barnyardgrass (Echinochloa crus-galli)

  • Foxtail (Setaria spp.)

  • Wild oats (Avena fatua)

  • Brome (Bromus spp.)

  • Couch grass (Elymus repens)

⚠️ Note: Not effective against broadleaf weeds.
