Package
Mode of Action
- Absorption: Taken up rapidly through the foliage
- Translocation: Moves both upward and downward inside plant tissues
- Accumulation: Targets growth points (meristems) of annual grass weeds
- Action: Stops fatty acid synthesis, causing cell division and development to cease, ultimately killing the plant
- Selectivity: Safe for use in broadleaf crops; highly active against gramineous weeds
Quizalofop-p-ethyl acts by targeting the acetyl-CoA carboxylase (ACCase) enzyme, which plays a crucial role in fatty acid biosynthesis within plant cells. This systemic herbicide is absorbed primarily through the leaves of susceptible grass weeds and is then translocated both upward and downward throughout the plant. Once inside, it concentrates at the meristematic tissues—the growing points—where it inhibits the ACCase enzyme, halting lipid production that is essential for cell membrane formation and energy storage.
The impact is highly specific to grassy weeds, making it safe for use in dicotyledonous crops like soybeans, peanuts, and a variety of vegetables. Symptoms on treated weeds begin with leaf discoloration and wilting within 3–5 days, followed by complete growth cessation and eventual plant death within 7–14 days, depending on environmental conditions.
What sets Quizalofop-p-ethyl apart is its rapid foliar absorption and dual-directional translocation, allowing it to effectively control not only visible grass weeds but also newly emerging ones. This mode of action offers a reliable post-emergence solution, ensuring the selective elimination of grasses while protecting valuable broadleaf crops.
Technical requirements for use
1. This product is a selective post-emergence stem and leaf treatment herbicide. In the early post-emergence period of soybean, the stem and leaf spray of weeds at the 3-5 leaf stage can effectively control various annual grass weeds in summer soybean fields.
2. Rice, wheat, corn, sugarcane and other gramineous crops are sensitive to this product, and should avoid drifting to adjacent crops during application to avoid phytotoxicity.
3. Do not use the medicine on windy days or when it is expected to rain within an hour.

Target Crops and Application Rates
Quizalofop-p-ethyl 5% EC is engineered for post-emergence use in a wide range of broadleaf crops that are particularly vulnerable to competition from annual grass weeds. Its high selectivity and crop safety profile make it especially suitable for soybeans, peanuts, and vegetable crops such as Chinese cabbage and watermelon. Additionally, it is also used in non-rice paddy areas where grass control is needed without harming broadleaf plants.
Application should occur during the early vegetative stage of grass weeds, ideally at the 3–5 leaf stage, when the plants are actively growing and most susceptible to ACCase inhibition. This ensures the herbicide is absorbed efficiently and translocated effectively to the growth points.

Spraying should be done using well-calibrated foliar spray equipment to ensure even coverage on the leaves of target weeds. Avoid spraying if rainfall is expected within one hour to prevent runoff and reduced efficacy. Results are typically visible within 3–5 days, with full control achieved in about two weeks.
Product Advantages
- Optically Pure Isomer: Higher bioactivity and better crop safety
- Dual-direction Translocation: Reaches deep root and shoot tissues
- Fast Absorption: Visible symptoms within 3–5 days after application
- Low Usage Rates: Effective even at low concentrations
- Highly Selective: Safe for dicots such as soybeans, peanuts, and vegetables
Quizalofop-p-ethyl 5% EC stands out in the post-emergent herbicide category due to its precision-targeted action, rapid performance, and exceptional crop safety profile. It is based on the optically active (R)-isomer, which is significantly more potent than the racemic mixture found in older formulations. This optical purity translates into higher herbicidal activity at lower doses, minimizing chemical input without compromising effectiveness.
One of the most significant advantages is its dual-directional translocation. Upon foliar absorption, the active ingredient moves both upward to new growth and downward to the roots, ensuring the entire plant is affected. This systemic action is crucial for reaching meristematic tissues deep within the plant, where fatty acid synthesis is disrupted, halting cell division and ultimately killing the weed.
Quizalofop-p-ethyl also shows visible symptoms quickly—typically within 3 to 5 days. Treated grass weeds exhibit yellowing and wilting, followed by full necrosis. This early symptom development provides farmers with a clear visual confirmation of product efficacy and allows them to make timely agronomic decisions if additional treatments are needed.
Despite its potency, the herbicide is highly selective, making it safe for a wide variety of dicotyledonous crops. This selectivity is especially beneficial in mixed cropping systems and rotational farming, where maintaining crop safety across different fields is essential.
In terms of logistics, low application rates and broad compatibility with other herbicides make it economical and easy to integrate into existing spray programs. It also reduces labor and fuel costs associated with repeat applications or mechanical weed removal.
Mixed Formulation Options
- Quizalofop-P-ethyl 6% + Fomesafen 16% EC
- Quizalofop-P-ethyl 5% + Fomesafen 25% EC
- Quizalofop-P-ethyl 5% + Benazolin-ethyl 12.5% EC
- Quizalofop-P-ethyl 2% + Benazolin-ethyl 12% EC
- Quizalofop-P-ethyl 2.5% + Benazolin-ethyl 15% EC
POMAIS offers an extended line of mixed formulations based on Quizalofop-p-ethyl, designed to meet the complex needs of modern weed management across diverse crop systems. These compound herbicides combine the grass-killing power of Quizalofop-p-ethyl with broadleaf herbicides, enabling farmers to tackle both grassy and broadleaf weeds in a single application. This not only saves time and labor but also reduces the need for multiple spray passes, lowering overall input costs.
For example, the combination Quizalofop-P-ethyl 6% + Fomesafen 16% EC is ideal for soybean and peanut fields where both annual grasses and resistant broadleaf species like pigweed or lambsquarters pose a threat. Fomesafen’s PPO-inhibiting action complements Quizalofop’s ACCase inhibition, creating a dual-mode mechanism that limits weed regrowth and delays resistance development.
Another widely used blend, Quizalofop-P-ethyl 5% + Benazolin-ethyl 12.5% EC, provides reliable results in brassica crops and Chinese cabbage, offering simultaneous control of common broadleaf weeds while retaining grass selectivity. This is particularly beneficial in regions with weed shifts due to repeated mono-mode herbicide usage.
Lower concentration variants such as Quizalofop-P-ethyl 2% + Benazolin-ethyl 12% EC are suitable for sensitive crops or when lighter weed pressure is present, offering economical protection without compromising safety or efficacy.
These mixed formulations also help distributors and agro-dealers offer ready-to-use, versatile products that simplify decisions for farmers and reduce compatibility concerns in the field. Each product is supported by POMAIS’s technical documentation, and available in customized packaging to meet regulatory and branding requirements in your target market.
Use Guidelines and Precautions
- Target Timing: Post-emergence of weeds; 3–5 leaf stage preferred
- Crop Sensitivity: Gramineous crops (e.g., rice, corn, wheat, sugarcane) are sensitive to this product; avoid drift to nearby fields
- Environmental Conditions: Do not apply during strong winds or before expected rainfall within one hour
- Compatibility: Compatible with many broadleaf herbicides but always conduct a tank-mix test before field use
Quizalofop-p-ethyl 5% EC must be applied with attention to timing, crop specificity, and environmental conditions to ensure maximum weed control and crop safety. This herbicide is specifically formulated for post-emergence use, meaning it should only be applied after weeds have sprouted—preferably at the 3–5 leaf stage, when grasses are still vulnerable and before they become competitive or develop resistance.
One of the most important considerations is crop selectivity. Quizalofop-p-ethyl is safe for dicotyledonous crops such as soybeans, peanuts, Chinese cabbage, watermelons, and rape. However, it is highly phytotoxic to gramineous crops, including rice, corn, wheat, sugarcane, and sorghum. Care must be taken to prevent spray drift to neighboring grass crops, particularly during aerial application or when using high-pressure nozzles.
To maximize effectiveness and minimize environmental loss, avoid spraying during strong winds or when rain is expected within an hour of application. Rainfall soon after spraying may wash off the herbicide before full absorption occurs, compromising its performance.
While Quizalofop-p-ethyl is compatible with many broadleaf herbicides, tank mixing should always be preceded by a jar test to confirm physical compatibility and prevent nozzle clogging or reduced efficacy. Some tank partners may alter the pH or physical behavior of the solution, especially under high-temperature conditions.
Farmers are also advised to follow a re-entry interval and pre-harvest interval as per local regulatory standards. Although Quizalofop-p-ethyl breaks down quickly in soil and does not persist in groundwater, appropriate application buffers should still be maintained near sensitive ecosystems.
By following these guidelines, you can optimize weed control while maintaining environmental safety, protecting nearby crops, and reducing the risk of herbicide resistance.
