Product Introduction

Product Overview

Quizalofop-P-ethyl is a highly selective, systemic post-emergence herbicide belonging to the aryloxyphenoxypropionate (FOP) chemical class. It is specifically designed to control annual and perennial grass weeds in broadleaf crops.
After application, the product is rapidly absorbed through the foliage and translocated to the growing points of weeds, inhibiting fatty acid synthesis and causing growth arrest followed by gradual death.

Mode of Action

Quizalofop-P-ethyl is an ACCase inhibitor (Acetyl-CoA carboxylase inhibitor).

Its activity features include:

Rapid foliar absorption
Strong systemic movement to meristematic tissues
Inhibition of fatty acid synthesis
Growth stops within hours, followed by chlorosis and necrosis
Complete weed death typically occurs within 1–3 week

Storage & Handling

Store in a cool, dry, and well-ventilated place
Avoid heat, spark, open flame, and direct sunlight
Keep away from children, food, and animal feed
Ensure containers remain sealed and avoid physical damage during transport

Safety Information

Wear protective gloves, masks, and clothing when handling

Avoid direct skin or eye contact and inhalation of mist

Wash hands and face after application

Prevent contamination of rivers, lakes, and irrigation channels

FAQ

Q1: What is Quizalofop-P-ethyl used for?

A: Quizalofop-P-ethyl is a selective post-emergence herbicide used to control annual and perennial grass weeds in broadleaf crops such as soybean, cotton, rapeseed, sunflower, and sugar beet.

Q2: Is Quizalofop-P-ethyl safe for broadleaf crops?

A: Yes. Quizalofop-P-ethyl is highly selective, targeting grass weeds while being safe for registered broadleaf crops when applied at recommended rates and growth stages.

Q3: When is the best time to apply Quizalofop-P-ethyl?

A: The best application timing is early post-emergence, when grass weeds are at the 2–5 leaf stage and actively growing. Early application ensures faster absorption and better weed control.

Q4: Can Quizalofop-P-ethyl be tank-mixed with other herbicides?

A: It can be tank-mixed with many broadleaf herbicides, but strong alkaline products should be avoided. A jar test is recommended before large-scale mixing.

Q5: How long does it take to see visible results after application?

A: Weed growth usually stops within 2–3 days, with visible yellowing and wilting appearing in 7–14 days, depending on weed species and environmental conditions.
