Overview

ONEKIL® 10% EC is an advanced combination herbicide from Dhanuka Agritech Limited, developed primarily for effective weed management in onion crops.

It combines Quizalofop Ethyl 4% and Oxyfluorfen 6%, providing two complementary modes of action. The formulation offers both systemic and contact activity, helping control a broad spectrum of narrow-leaf and broad-leaf weeds after emergence.

Dhanuka describes ONEKIL as a complete solution for weed management in onion, with 1–2 hours of rainfastness and longer residual control.

Dhanuka's official product page confirms the composition, formulation, pack sizes, rainfastness and onion recommendation.

About the Product

ONEKIL provides weed control through the combined activity of Quizalofop Ethyl and Oxyfluorfen.

The product can be absorbed through the leaves and roots of weeds. Following foliar absorption, the systemic component moves downward through the phloem, while root absorption allows movement upward through the xylem. This complementary movement helps provide effective weed suppression and residual activity.

Key Features

• Contains Quizalofop Ethyl 4% + Oxyfluorfen 6% EC.
• Dual active-ingredient technology.
• Post-emergence herbicide.
• Provides both contact and systemic activity.
• Controls narrow-leaf weeds.
• Controls broad-leaf weeds.
• Absorbed through foliage and roots.
• Provides excellent translocation activity.
• Offers longer residual weed control.
• Provides 1–2 hours rainfastness.
• Specifically recommended for onion crop.
• Helps reduce weed competition for nutrients, water and sunlight.

Recommended Crop & Target Weeds

Onion

ONEKIL is specifically recommended by Dhanuka for onion.

Narrow-Leaf Weeds

• Digitaria sanguinalis — Crabgrass
• Cyperus rotundus — Motha
• Echinochloa spp.

The exact weed spectrum should be checked against the current product label before application.

Application Guidelines

Application Method

Apply ONEKIL as a post-emergence foliar spray when the target weeds are actively growing.

Ensure uniform coverage of the weeds while avoiding unnecessary spray contact with non-target crops.

Recommended Dosage

Onion

400 ml per acre

Use approximately 150 litres of water per acre, according to Dhanuka's official recommendation.

A commonly published application reference is:

2 ml per litre of water

or approximately:

30 ml per 15-litre pump

with the overall field dose maintained at 400 ml/acre.

Best Application Stage

Apply when weeds are young and actively growing.

Recommended Weed Stage

2–3 leaf stage

Some product references specify the 3–4 leaf stage; therefore, the current Dhanuka label should be treated as the final authority for the exact application timing.

Mode of Action

ONEKIL combines two active ingredients with complementary herbicidal activity.

Quizalofop Ethyl – Grass Weed Control

Quizalofop Ethyl is an ACCase-inhibiting herbicide that interferes with fatty-acid synthesis in susceptible grasses.

This stops growth of narrow-leaf weeds and ultimately leads to their death.

Oxyfluorfen – Broad-Spectrum Contact Activity

Oxyfluorfen acts primarily as a contact herbicide and disrupts plant cell membranes through lipid peroxidation.

It provides strong activity against susceptible broad-leaf weeds and some grasses.

Combined Action

The combination provides:

Foliar absorption → Systemic translocation + Contact activity → Weed growth inhibition → Weed desiccation and death

Benefits

• Broad-spectrum weed management.
• Controls both narrow-leaf and broad-leaf weeds.
• Dual mode of action.
• Contact and systemic activity.
• Absorbed through leaves and roots.
• Excellent translocation.
• Longer residual weed control.
• 1–2 hour rainfastness.
• Reduces competition for water and nutrients.
• Helps maintain a cleaner onion field.
• Supports better crop growth and development.
• Convenient EC formulation.
