Adama Narkis is a broad-spectrum, selective, systemic, and post-emergence herbicide that works effectively against grasses, sedges, and broadleaf weeds that affect paddy crops. It works by inhibiting an essential enzyme, which stops weeds from producing essential amino acids, killing them eventually. The Narkis herbicide is especially designed for weeds that harm paddy crops, providing targeted protection. This herbicide is also safe to use as it has strong selective properties.
Key Features and Benefits of Narkis Herbicide:
Broad-Spectrum: Adama Narkis herbicide can be used against grassy, sedges, and broadleaf weeds.
Complete Weed Kill: The Narkis herbicide stops amino acid synthesis, arresting cell division and causing complete weed death.
Selective Properties: This herbicide has selective properties, as it affects harmful weeds while not damaging the rice crops.
Rainfast Application: Adama Narkis herbicide can not be washed away easily by the rain, providing effective results in harsh weather.
Dual Uptake: Adama Narkis is absorbed through the leaf and root system, offering quick results.
Narkis Herbicide Uses — Target Weeds and Crop:
Narkis herbicide uses cover all major weed categories in Paddy:
Grassy Weeds: Echinochloa crus-galli (Barnyard Grass), Echinochloa colona (Jungle Rice), Ischaemum rugosum (Wrinkled Grass)
Sedges: Cyperus difformis (Variable Flatsedge), Cyperus iria (Rice Flatsedge), Fimbristylis miliacea (Globe Fringerush)
Broadleaf Weeds: Eclipta alba (Bhringraj), Ludwigia parviflora, Monochoria vaginalis, Alternanthera philoxeroides, Sphenoclea zeylanica
Registered Crop: Paddy (Rice) — transplanted, direct-seeded, and nursery
Adama Narkis Dose — Recommended Dose:
The Narkis herbicide dose per litre of water is approximately 0.5–0.6 ml per litre — equivalent to 100–120 ml per acre in 150–200 litres of water and 7.5–9 ml per 15L pump.
Crop | Target Weeds | Dose Per Acre | Per 15L Pump | Timing | PHI |
Paddy (Transplanted) | Grasses, Sedges, Broadleaf Weeds | 100–120 ml | 7.5–9 ml | 15–25 days after transplanting — weeds at 2–5 leaf stage | As per label |
Paddy (Direct-Seeded) | Grasses, Sedges, Broadleaf Weeds | 100–120 ml | 7.5–9 ml | 15–20 days after sowing — weeds at 2–5 leaf stage | As per label |
How To Use Adama Narkis Herbicide:
Drain the paddy field water completely before spraying Narkis herbicide — weeds must be fully exposed above the water level for good spray contact and leaf absorption.
Measure 100–120 ml of Adama Narkis per acre as per the dose table above.
Add the measured quantity to a sprayer tank with 150–200 litres of clean water and mix well — do not reduce the water volume below 150 litres per acre as this reduces field coverage uniformity.
Use a flat fan nozzle for uniform broadcast coverage — do not mix the formulation indoors and always prepare the spray solution outdoors in a well-ventilated area.
Spray uniformly across the entire field surface when weeds are at the 2–5 leaf stage — do not apply after the 5-leaf weed stage as efficacy drops significantly with weed maturity.
Wait 48–72 hours after spraying before reflooding the field — the standing water after this interval helps suppress new weed flushes following the initial herbicide kill.
Do not apply Narkis herbicide if rain is expected within 6 hours of spraying.
Do not apply directly on top of the rice crop — direct the spray onto the weed and field surface using a flat fan nozzle.
Best Time to Apply:
Apply Adama Narkis in the early morning or late evening on actively growing weeds at the 2–5 leaf stage. For transplanted Paddy, the optimum window is 15–25 days after transplanting. For DSR, apply 15–20 days after sowing. Always drain the field before spraying and reflood 48–72 hours after application.
Frequency of Application and Re-Entry Period:
Frequency of Application: One well-timed post-emergence application at the 2–5 weed leaf stage is generally sufficient for season-long weed management in Paddy. A second application may be needed if a new weed flush emerges after the residual period.
Re-Entry Period: Do not enter the treated paddy field for at least 12 hours after spraying. Allow the spray to settle fully before re-entry without protective gear.
Tank-Mix Compatibility: Narkis herbicide is compatible with most insecticides and fungicides. Maintain a 4–7 day gap between Adama Narkis and other ALS inhibitor herbicides to avoid rice stunting. Always perform a jar test before mixing with unfamiliar products.
Important Notes:
Apply Narkis herbicide only to Paddy — do not spray on other crops as it will damage non-rice species.
Do not reduce the water volume below 150 litres per acre.
Slight temporary yellowing of rice leaves may appear after application — the crop recovers fully within 10–14 days.
Dispose of used gloves after mixing the product and read all instructions carefully before use.
Safety Precautions and Handling:
Read the instructions carefully before using Adama Narkis.
Wear gloves, goggles, and a face mask before handling or spraying Narkis herbicide.
Do not mix the formulation indoors to maintain safety — always mix outdoors in a well-ventilated area.
Dispose of gloves after mixing the product.
Do not apply the herbicide directly on top of crops — direct the spray at the weed surface.
