Quizalofop-Ethyl 5% EC

Quizalofop Ethyl 5% EC

Quizalofop Ethyl 5% EC is a selective, systemic post-emergence herbicide from the Aryloxy Phenoxy Propionate chemical group, specially formulated at a lower active concentration for targeted grassy weed management in broadleaf crops. This lower-strength formulation is suitable for grassy weed situations requiring accurate, cost-effective control with the same reliable systemic action as higher-concentration versions of this molecule.

How Quizalofop Ethyl 5% EC Works

Once sprayed on actively growing grassy weeds, Quizalofop Ethyl 5% EC is rapidly absorbed through the weed’s leaves and stems. It then moves systemically through the entire weed plant — from the sprayed leaves all the way down to the underground growing points and roots. Inside the weed, the active ingredient inhibits Acetyl-CoA Carboxylase (ACCase), the enzyme responsible for fatty acid synthesis. Without fatty acids, the weed cannot form new cell membranes or continue normal metabolic processes, causing growth to stop, the plant to wilt, and eventually die completely within 7 to 10 days of application.

Why Farmers Choose This Herbicide

One of the most appreciated qualities of Quizalofop Ethyl 5% EC is its true selectivity — it controls grassy weeds very effectively while remaining completely safe for broadleaf crops like soybean, cotton, groundnut, black gram, sunflower, and onion when used as directed. Many farmers growing these crops face a common challenge where grassy weeds grow alongside the main crop and compete heavily for water, sunlight, and soil nutrients. Left uncontrolled, these weeds can significantly reduce the final yield, making a reliable selective herbicide like this one a valuable part of any crop management program.

Because Quizalofop Ethyl 5% EC kills weeds all the way down to their roots and growing points, even perennial grass weeds that usually regrow from underground parts are eliminated completely. Treated weeds are unable to regenerate after a single well-timed application, reducing the overall weed pressure in the field for a longer period compared to contact-only herbicides that only kill the above-ground portions of the weed. The formulation also shows good rainfastness once absorbed into the weed leaf, meaning that even if rain falls a few hours after spraying, the herbicide’s effectiveness is not significantly reduced.

Key Benefits

• Controls annual and perennial grassy weeds including Echinochloa, Eleusine, Cynodon, and wild sorghum
• Also controls volunteer paddy, Johnson grass, and crabgrass
• Highly selective — safe for soybean, cotton, groundnut, and other broadleaf crops
• Systemic action reaches roots — weeds cannot regenerate after treatment
• Visible weed stress within days, complete control within 7 to 10 days
• Rainfast after absorption — remains effective even after rain
• Cost-effective lower-concentration formulation for precise weed management

Why Crop Nutrition Matters Alongside Weed Control

Weed control removes competition and gives the main crop more access to water, nutrients, and sunlight. But the crop also needs strong nutritional support to take full advantage of that weed-free window. Products like Humic Acid 98% Flakes help improve soil nutrient availability and build stronger roots, while Power PGR Liquid helps the crop use that extra energy for better flowering and fruit setting, leading to higher overall yield at harvest.

Safety Tips & Precautions

• Apply only as a post-emergence spray when grassy weeds are actively growing at the 2 to 4 leaf stage
• Do not apply on grass crops such as paddy, wheat, maize, or sugarcane — serious crop damage will occur
• Apply under adequate soil moisture for best herbicide uptake and weed control activity
• Avoid spraying during strong winds to prevent drift onto sensitive neighbouring crops or non-target areas
• Do not spray if rain is expected within 4 hours of application
• Wear gloves, mask, and protective clothing while mixing and spraying
• Avoid direct contact with skin and eyes during application
• Wash hands and exposed skin thoroughly with soap after spraying
• Keep away from children, animals, and food or feed storage areas

Storage Instructions

Store Quizalofop Ethyl 5% EC in a cool, dry place away from direct sunlight and moisture. Keep the container tightly sealed and out of reach of children and animals.
