Quizalofop-P-ethyl 50 g/L is a systemic, highly selective post-emergence herbicide.
It is especially effective against annual and perennial grasses in broadleaf crops such as soybean, peanut, cassava, sesame, onion, etc.
High efficacy: Quickly eliminates weeds and minimizes competition for nutrients.
Selective: Safe for crops; little to no impact on broadleaf crop species.
Easy to use: Simple dilution and application; environmentally friendly.
Quizalofop-P-ethyl rapidly converts into its active acid form, Quizalofop-P, inside plant tissues.
This active compound inhibits fatty acid synthesis by blocking the enzyme acetyl-CoA carboxylase (ACCase), which is essential for cell membrane and lipid formation in grass weeds.
After foliar application, the product is absorbed and translocated to meristematic tissues within 24 hours.
ACCase inhibition leads to growth cessation and eventual death of grass weeds within 5–7 days after spraying.

Read the label carefully: Always read the product label and instructions before mixing and applying the pesticide.
Check permitted application rates: Use the product only within the recommended application rates to ensure effectiveness and compliance.
Prepare personal protective equipment (PPE): Wear appropriate PPE such as a respirator or dust/mist mask, protective gloves, safety boots, and a raincoat when mixing or spraying.
Choose the proper spraying time: Apply in the early morning or late afternoon; avoid spraying during strong sunlight or high winds.
