Quizalofop Ethyl 4% + Oxyfluorfen 6% EC

About Quizalofop Ethyl 4% + Oxyfluorfen 6% EC

Quizalofop Ethyl 4% + Oxyfluorfen 6% EC (Emulsifiable Concentrate) is a highly specialized, selective, dual-action post-emergence herbicide. Commonly sold under premium trade names like Dhanuka's OneKil, Godrej's Portraitt, or IIL's Oxim, this ready-mix combination is highly valued by vegetable farmersespecially onion and garlic growersfor tackling both narrow-leaf and broadleaf weeds in a single spray.

Mode of Action: The "Double Attack"

This combination formulation targets weeds through two completely distinct chemical pathways:

• Quizalofop Ethyl (4%) Systemic Action: As an ACCase inhibitor, it is rapidly absorbed by the leaves and moves systemically throughout the plant, traveling down to the roots and growing points (meristems) of grassy (narrow-leaf) weeds. It shuts down fatty acid synthesis, causing the core of the grass to rot ("dead heart") and die from the inside out.

• Oxyfluorfen (6%) Contact Action: Acting as a PPO inhibitor, it works via direct contact on broadleaf weeds. In the presence of sunlight, it induces lipid peroxidation, destroying fungal and plant cell membranes rapidly. This causes visible drying, burning, and death of broadleaf weeds within 24 to 48 hours.

• Residual Soil Barrier: When it hits the ground, it forms a light chemical barrier on the soil surface that helps suppress newly emerging weed seedlings for several weeks.

Primary Uses and Target Crops

While engineered primarily as a lifesaver for all types of onion and garlic crops, it is also highly effective on select broadleaf field crops.

Note on Motha (Nutsedge): This herbicide will burn the top leaves and temporarily suppress Cyperus rotundus (Motha), but it will not permanently eradicate the underground tubers/nuts.

Dosage & Application Guidelines

To achieve absolute weed control without stalling or stressing your primary crop, precise application rules must be followed:

• Standard Dosage: 400 ml per acre.

• Water Volume: Use 200 liters of water per acre. Never under-dose on water volume, as high concentration can cause leaf injury to your crop.

• Application Timing: Apply 15 to 25 Days After Transplanting (DAT) when weeds are actively growing at the 2-to-3 leaf stage.

Crucial Application Rules (To Avoid Crop Burn)

• The 2-Leaf Rule: Do not spray if your onion or garlic seedlings are too young and have fewer than 2 true leaves.

• NO Extra Stickers/Spreaders: Do not add any silicon-based stickers, spreaders, or "chipko" formulas to the tank. This formulation already contains advanced adjuvants. Adding more will strip away the crop's natural protective leaf wax, resulting in severe crop burning.

• Soil Moisture: Always ensure there is ample moisture in the soil at the time of spraying. Do not apply under heavy drought stress or during intense midday heat.

• Nozzle Choice: Use a Flat Fan or Flood Jet nozzle for uniform, downward coverage on the weeds.

Common Observations Post-Spray

Cosmetic Spotting: It is perfectly normal to see minor white or yellow dots on your onion/garlic leaves a couple of days after spraying. This is a temporary cosmetic side effect of the contact action of Oxyfluorfen. The crop will quickly outgrow this, and new leaves will emerge completely green and healthy without any impact on bulb yield.
