UPL Strider is a broad-spectrum, selective, and systemic herbicide that specially protects rice fields. This herbicide works by interfering with an essential enzyme, leading to the prevention of cell division and stopping weed growth. UPL Strider herbicide is also very versatile, as it can be used as a post-emergent and has strong rainfast properties as well, providing effective protection in harsh weather.
Broad-Spectrum: The Strider herbicide is effective against grasses, sedges, and broadleaf weeds, making it highly versatile.
Complete Weed Kill: This herbicide causes complete weed death from roots to shoots, providing healthier yields.
Rainfast Application: UPL Strider herbicide cannot be washed away by the rain easily after a certain time of application.
Cost-Effective Application: The Strider herbicide provides effective results at low doses, making it very cost-efficient.
Safe to Use: UPL Strider herbicide has selective properties, which make it safe to use as it only targets weeds while not harming the crops.
Strider herbicide uses cover grasses, sedges, and broadleaf weeds in Paddy:
Grassy Weeds: Echinochloa colona (Jungle Rice / Swarna), Echinochloa crus-galli (Barnyard Grass), Leptochloa chinensis (Chinese Sprangletop), Dactyloctenium aegyptium (Crowfoot Grass)
Sedges: Cyperus rotundus (Motha / Nutsedge), Cyperus difformis (Rice Flatsedge), Cyperus iria, Fimbristylis miliacea
Broadleaf Weeds: Eclipta alba (Bhringraj), Caesulia axillaris, Monochoria vaginalis, Sphenoclea zeylanica, Ludwigia spp.
Registered Crop: Paddy (Rice) — transplanted, direct-seeded, and nursery
The Strider herbicide dosage is 100 ml per acre — equivalent to 25–30 ml per 15L pump in 150–200 litres of water per acre.
Crop | Target Weeds | Dose Per Acre | Per 15L Pump | Timing | PHI |
|---|---|---|---|---|---|
Paddy (Transplanted) | Grasses, Sedges, Broadleaf Weeds | 100 ml | 15 ml | 15–25 days after transplanting — weeds at 2–5 leaf stage | As per label |
Paddy (Direct-Seeded) | Grasses, Sedges, Broadleaf Weeds | 100 ml | 15 ml | 15–20 days after sowing — weeds at 2–5 leaf stage | As per label |
Rice Nursery | Grasses, Sedges, Broadleaf Weeds | 100 ml | 15 ml | When weeds are at the 2–3 leaf stage | As per label |
Drain the paddy field water completely before spraying Strider herbicide — weeds must be fully exposed to air and not submerged for good spray contact and absorption.
Measure 100 ml of UPL Strider 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 coverage uniformity.
Use a flat fan nozzle or flood-jet nozzle for uniform broadcast coverage — never use the hollow cone nozzle used for insecticides.
Spray uniformly across the entire field surface when weeds are at the 2–5 leaf stage — apply no later than the 5-leaf weed stage for full efficacy.
After spraying, wait 48–72 hours before reflooding the field with 3–5 cm of water — the standing water helps suppress new weed flushes after the herbicide kill.
Do not spray if rain is expected within 6 hours of application.
Do not apply if the rice crop is under stress — drought, disease, fertilizer burn, or pest damage — as crop injury may occur under these conditions.
Apply UPL Strider in the early morning or late evening when conditions are calm. For transplanted Paddy, apply 15–25 days after transplanting. For DSR, apply 15–20 days after sowing. Always target the 2–5 weed leaf stage — applying to older weeds significantly reduces control efficacy.
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.
Tank-Mix Compatibility: Strider herbicide is compatible with most insecticides and fungicides. Maintain a 4–7 day gap between UPL Strider and other ALS inhibitor herbicides like Pyrazosulfuron to avoid rice stunting. Always perform a jar test before mixing with unfamiliar products.
Apply Strider 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 — insufficient water volume reduces coverage and may cause uneven weed control.
Slight temporary yellowing of rice leaves may occur at higher doses or in cold weather — the crop recovers fully within 10–14 days without yield loss.
Wear gloves, goggles, and a face mask before handling or spraying Strider herbicide.
Do not eat, drink, or smoke during mixing or application.
Avoid direct contact with skin and eyes — rinse immediately with clean water for 15 minutes if contact occurs.
Do not allow spray drift onto adjacent non-paddy crops.
Keep children, pets, and livestock away from treated fields for at least 12 hours.
Wash all exposed skin thoroughly with soap and water after every spray session.
Triple rinse empty containers, puncture, and dispose of per local waste guidelines.
Store UPL Strider in its original sealed container in a cool, dry place away from direct sunlight.
Keep away from food, animal feed, and seeds.
Store out of reach of children and farm animals.
Storage Temperature: Below 35°C.
Shelf Life: As indicated on the product label.
