# Quizalofop-p-ethyl Herbicide
Quizalofop-p-ethyl is an improved version of the original Quizalofop herbicide, with the non-active optical isomer removed during synthesis. Its mechanism of action is similar to that of Quizalofop, working by being absorbed through the leaves of grass weeds and translocated both upwards and downwards within the plant. It accumulates in the shoot tips and meristematic regions, inhibiting fatty acid synthesis, which leads to the eventual death of the weed.

Quizalofop-P-Ethyl is a selective, post-emergence herbicide specially formulated to control annual and perennial grassy weeds in various broadleaf crops. An advanced derivative of Quizalofop, it has enhanced purity and effectiveness due to the removal of the non-active optical isomer during synthesis, ensuring superior weed control performance.
## Available Formulations
- **Quizalofop-P-Ethyl 95% TC (Technical Grade)**
- **Quizalofop-P-Ethyl 5% EC (Emulsifiable Concentrate)**
- **Quizalofop-P-Ethyl 12.5% EC (Emulsifiable Concentrate)**
- **Quizalofop-P-Ethyl 20% EC (Emulsifiable Concentrate)**
These formulations allow flexibility to meet various crop needs and application requirements.
## Target Crops
Quizalofop-P-Ethyl herbicide is particularly effective in broadleaf crop production systems, including:
- Soybeans
- Sugar beet
- Rapeseed (Canola)
- Potato
- Flax
- Peas
- Fava beans
- Tobacco
- Watermelon
- Cotton
- Peanuts
- Broadleaf vegetables
- Fruit trees
- Forestry nurseries and young forest management
- Alfalfa
## Target Weeds Controlled
Quizalofop-P-Ethyl is highly effective against common grassy weeds such as:
- Barnyardgrass (*Echinochloa crus-galli*)
- Foxtail (*Setaria spp.*)
- Wild oats (*Avena fatua*)
- Brome (*Bromus spp.*)
- Couch grass (*Elymus repens*)
**Note:** This herbicide selectively targets grassy weeds and has no impact on broadleaf weeds, ensuring crop safety.
## Mechanism of Action
Quizalofop-P-Ethyl herbicide is absorbed through the leaves of grassy weeds and then rapidly translocated both upwards and downwards throughout the plant. It accumulates in shoot tips and meristematic regions, inhibiting the enzyme acetyl-CoA carboxylase (ACCase). This disruption prevents fatty acid synthesis, essential for cell membrane integrity and plant growth, ultimately causing plant death.
## Key Features
- **Selective Action:** Exceptional selectivity allows safe application in broadleaf crops without causing crop injury.
- **Rapid Action:** Demonstrates quick efficacy and stable weed control performance under diverse environmental conditions, including varied rainfall, temperature, and humidity levels.
- **Dual-Translocation:** Moves efficiently within weeds, providing complete systemic control from leaves to roots.
- **High Efficacy:** Provides outstanding control of grassy weeds, protecting crop yield and quality.
## Application Guidelines
- **Timing:** Apply post-emergence when grass weeds are actively growing, ideally at an early growth stage for best results.
- **Method:** Foliar spray using recommended concentrations according to weed species and growth stages.
- **Weather Tolerance:** Reliable effectiveness in varying weather conditions, minimizing risk from rain shortly after application.
## Recommended Safety and Storage
- Store in cool, dry conditions away from direct sunlight and food products.
- Use appropriate protective clothing, gloves, and goggles when handling and applying the product.
- Follow all label instructions and local regulatory guidelines.
