Dhanuka Ozone is a powerful herbicide that offers a contact mode of action. It works by penetrating the green foliage of the weeds and starts producing Reactive Oxygen Species in the weeds, causing rapid cell membrane damage. The Ozone herbicide is effective against a broad range of weeds while having strong rainfast properties, ensuring effective results with each use.
Quick Action: Dhanuka Ozone herbicide works within minutes of application, with visible signs, providing quick weed relief.
Rainfast Application: This herbicide cannot be washed away easily after application, providing effective results in harsh rainy weather.
Broad-Spectrum: Dhanuka Ozone herbicide controls a wide range of annual broadleaf weeds, grassy weeds, and sedges.
Residue-Free: This herbicide leaves behind no residue after application, ensuring safety for the growing crops.
Versatile Uses: Ozone herbicide can be used on Tea, Potato, Cotton, Rubber, Paddy, Wheat, and Grapes, as well as non-cropped areas.
It can be used for agricultural and non-agricultural weed management like:
Annual Broadleaf Weeds: Amaranthus spp. (Pigweed), Trianthema spp. (Horse Purslane), Parthenium spp. (Congress Grass), Euphorbia spp.
Grassy Weeds: Echinochloa spp. (Barnyard Grass), Digitaria spp. (Crabgrass), Cynodon dactylon (Bermuda Grass)
Registered Application Areas: Tea Plantations, Cotton Fields, Paddy (pre-sowing), Potato Fields, Rubber Plantations, Wheat Fields, Vineyards (Grapes), Aquatic Weeds, Roadsides, Bunds, Irrigation Channels
This herbicide’s dose per litre ranges from 1.7 to 8.5 ml per litre of water depending on crop, weed species, and application method — always apply as a directed ground-level spray on young, actively growing weeds.
Crop / Use | Dose Per Acre | Per 15L Pump | Per Litre | Notes |
|---|---|---|---|---|
Tea | 340–1700 ml per acre | 25.5–127.5 ml | 1.7–8.5 ml | Directed spray between rows |
Potato | 400–850 ml per acre | 30–63 ml | 2–4.25 ml | Pre-plant directed spray |
Cotton | 500–850 ml per acre | 37.5–63 ml | 2.5–4.25 ml | Directed spray between rows |
Rubber | 500–1000 ml per acre | 37.5–75 ml | 2.5–5 ml | Directed inter-row spray |
Paddy | 500–1600 ml per acre | 37.5–120 ml | 2.5–8 ml | Pre-sowing directed spray |
Wheat | 1700 ml per acre | 127.5 ml | 8.5 ml | Directed spray |
Grapes | 1000 ml per acre | 75 ml | 5 ml | Directed inter-row spray |
Aquatic Weeds | As per area | — | As per label | Spray directly on weed surface |
Measure the required dose of this herbicide as per the crop-wise table above — always use the lower dose for young weeds and higher dose for dense or mature growth.
Add the measured quantity to the sprayer tank half-filled with clean water and mix well — fill with remaining water and agitate before spraying.
Use a flat fan nozzle for directed ground-level application — always direct the spray onto weed foliage, keeping it away from desirable crop plants.
Apply as a directed spray on young, actively growing weeds at the ground level; Dhanuka Ozone herbicide gives the fastest and most complete kill on weeds at the early growth stage.
Do not spray during windy conditions; spray drift onto crop foliage will cause severe crop damage as this herbicide is non-selective.
Apply in the early morning or late evening; avoid spraying during extreme heat or strong winds.
Do not spray if rain is expected within 30 minutes, although Dhanuka Ozone herbicide becomes rain-fast very quickly, a minimal dry period ensures complete initial absorption.
Rinse all sprayer equipment thoroughly with clean water after use — Paraquat residues can damage the next crop sprayed if not flushed properly.
Apply Ozone herbicide in the early morning or late evening on young, actively growing weeds. Target the 2–4 leaf growth stage for the fastest and most complete contact kill. For pre-planting applications, allow treated weeds to die completely before sowing or transplanting.
Frequency of Application: Apply as needed for each new flush of weed emergence. One well-timed application per weed flush is generally sufficient given the fast contact action of Dhanuka Ozone herbicide. Do not exceed label-recommended application rates.
Re-Entry Period: Do not enter treated areas for at least 24 hours after spraying. Paraquat Dichloride is highly toxic — always wear full protective gear during application and avoid treated field re-entry until the spray has fully dried and settled.
Tank-Mix Compatibility: Ozone Herbicide is generally used as a standalone product. Consult the label or a certified agronomist before mixing with any other product.
Important Note: Dhanuka Ozone herbicide is restricted in Kerala State — do not purchase or use in Kerala.
Wear chemical-grade gloves, a full face mask, goggles, and a complete protective suit before handling or spraying Dhanuka Ozone herbicide — skin and inhalation exposure is extremely dangerous.
Do not eat, drink, or smoke during mixing or application — never remove protective gear while in or near the spray area.
Avoid all direct skin, eye, and inhalation exposure — if contact occurs, immediately rinse with large amounts of clean water for at least 15–20 minutes and seek urgent medical attention.
Do not allow spray drift onto crop plants, neighbouring fields, water bodies, or populated areas — Paraquat is non-selective and highly toxic to all exposed organisms.
Keep children, pets, and livestock strictly away from treated areas for at least 48 hours.
Store and transport only in original labelled containers — never transfer to food containers, bottles, or unlabelled vessels.
In case of accidental swallowing, go to the nearest hospital immediately — do not induce vomiting. Take the product container to the doctor.
Triple rinse empty containers, puncture, and dispose of per CIBandRC and local chemical waste disposal regulations.
Store Ozone herbicide in its original sealed container in a cool, dry, locked location away from direct sunlight, heat sources, and food items.
Keep strictly away from food, animal feed, seeds, and water sources.
Store out of reach of children and farm animals at all times.
Do not store in temperatures above 35°C or in freezing conditions.
Storage Temperature: Between 5°C and 35°C.
