UPL Iris is a broad-spectrum, selective, and post-emergent herbicide that is effective against various grassy and broadleaf weeds. It works by inhibiting an essential enzyme that causes the gathering of toxic compounds that destroy the weed, and stopping the creation of new cell membranes. The UPL Iris herbicide ensures complete weed removal with its dual-action formula and quick knockdown effect.
Key Features and Benefits of Iris Herbicide:
Dual Mode of Action: UPL Iris combines two different modes of action, providing effective resistance management against weeds.
Broad-Spectrum: The Iris herbicide is effective against both grassy and broadleaf weeds, making it very effective.
Quick Knockdown: The UPL Iris herbicide is absorbed quickly upon absorption and offers quick results for rapid weed relief.
Rainfast Properties: This herbicide becomes rainfast after 2 hours of application, and cannot be washed away by the rain easily.
Prolonged Effects: UPL Iris herbicide provides long-lasting safety through a strong residual action, reducing the frequency of application.
Iris Herbicide Uses — Target Weeds and Crop:
Iris herbicide uses cover both grassy and broadleaf weeds in soybeans:
Annual Grassy Weeds: Echinochloa colona (Jungle Rice), Echinochloa crus-galli (Barnyard Grass), Digitaria sanguinalis (Crabgrass), Dactyloctenium aegyptium (Crowfoot Grass), Eleusine indica (Goosegrass)
Broadleaf Weeds: Amaranthus viridis (Slender Amaranth), Commelina benghalensis (Kena), Trianthema portulacastrum (Horse Purslane), Digera arvensis (Smooth Pigweed), Euphorbia hirta (Asthma Weed), Portulaca oleracea (Purslane)
Registered Crop: Soybean
UPL Iris Dose — Recommended Dose:
The Iris Herbicide Dose Per Litre is 2 ml per litre of water — equivalent to 400 ml per acre in 200 litres of water and 30 ml per 15L pump.
Crop | Target Weeds | Dose Per Acre | Per 15L Pump | Per Litre | Timing | PHI |
Soybean | Grassy and Broadleaf Weeds | 400 ml | 30 ml | 2 ml | 15–25 DAS — weeds at 2–4 leaf stage | As per the label |
Note: Use a spreader or sticker adjuvant (e.g., IFC Super Sticker) with UPL Iris for improved leaf wetting, absorption, and weed control performance. Do not tank-mix with other herbicides — use Iris herbicide as a standalone application; only adjuvants are permitted to be combined.
How To Use UPL Iris Herbicide:
Read the label instructions carefully before using Iris herbicide.
Measure 2 ml of UPL Iris per litre of water — 400 ml per acre in 200 litres of clean water.
Add the measured quantity to the sprayer tank with the required water volume and mix well before spraying.
Add the recommended adjuvant (IFC Super Sticker or similar) to improve leaf coverage and absorption efficiency.
Use a high-volume knapsack sprayer for effective and uniform coverage across the entire Soybean field surface.
Apply at the correct 2–4 weed leaf stage, 15–25 days after sowing, is the optimum application window for UPL Iris.
Apply on a non-windy, non-rainy day during early morning or late afternoon — do not spray if rainfall is expected within 2–3 hours of application.
Ensure weeds are actively growing at the time of application for best absorption and kill efficacy.
Best Time to Apply:
Apply Iris herbicide in the early morning or late afternoon. The optimum application window is 15–25 days after Soybean sowing when weeds are in the 2–4 leaf stage and actively growing — applying too early or too late significantly reduces weed control effectiveness from a single spray.
Frequency of Application and Re-Entry Period:
Frequency of Application: One well-timed early post-emergence application of UPL Iris at the 2–4 weed leaf stage is generally sufficient for season-long weed control in Soybean. The residual effect of Iris herbicide suppresses newly germinating weed flushes after the initial spray.
Re-Entry Period: Do not re-enter treated fields immediately after application — follow the label safety interval and allow the spray to dry fully before re-entry.
Tank-Mix Compatibility: Iris herbicide cannot be mixed with any other herbicides — it has been recommended to be used as a standalone herbicide. Only compatible adjuvants like IFC Super Sticker are permitted to be added to the spray solution.
Important Notes:
Apply Iris herbicide only when weeds are actively growing — applying to stressed, dormant, or waterlogged weeds reduces efficacy.
Always wear protective equipment — gloves and goggles — during application.
Thoroughly clean sprayer equipment after Iris herbicide application before use on any other crop.
Safety Precautions and Handling:
Wear suitable protective equipment — gloves, goggles, and a face mask — during application of UPL Iris.
Do not eat, drink, or smoke during mixing or spraying.
Avoid direct skin and eye contact — rinse immediately with clean water if contact occurs.
Do not allow spray drift onto non-Soybean crops or adjacent fields.
Keep Iris herbicide away from children, animals, food, and water sources.
Thoroughly clean sprayer equipment after use.
Triple rinse empty containers, puncture, and dispose of per local waste guidelines.
