About Penoxsulam 1% + Pendimethalin 24% SE
Penoxsulam 1% + Pendimethalin 24% SE is a pre-mixed, high-efficiency herbicide formulation designed primarily for weed control in Direct-Seeded Rice (DSR) and transplanted rice. This Suspension Emulsion (SE) combination offers both pre-emergence and early post-emergence activity, providing a robust solution against broad-spectrum weeds.
Agricultural Benefits & Efficacy
Synergistic Weed Control: The combination of Penoxsulam (ALS inhibitor) and Pendimethalin (cell division inhibitor) provides synergistic effects, offering better control over complex weed flora (grasses, sedges, and broadleaf weeds) than either herbicide used alone.
High Efficiency in DSR: Studies have shown that this mixture, particularly at a dosage of 625 g/ha, significantly reduces the density and dry biomass of weeds like Echinochloa colona, Cyperus iria, and various grass weeds.
Yield Enhancement: By controlling weeds during the critical early growth phase, this mixture can significantly increase rice yield. One study reported a 187% increase in grain yield of DSR compared to untreated controls.
Broad Spectrum Action: It is highly effective against major rice weeds, including Echinochloa crus-galli (barnyard grass) and sedges.
Flexible Application Window: It can be applied as a pre-emergence or early post-emergence spray, typically 03 days after sowing (DAS) in DSR or 0-7 days after transplanting (DAT) in transplanted rice, providing a 34 week residual control against weed regrowth
Ready-Mix Formula: It combines two active ingredients with different modes of action (MOA) into one stable, easy-to-use formulation, simplifying application for farmers.
Reduced Labor and Costs: By effectively controlling weeds in the early stages, it significantly reduces the need for costly manual weeding and reduces labor dependency, especially crucial during peak seasons.
Long-Lasting Residual Protection: Pendimethalin creates a thin layer of herbicide on the soil surface that prevents new weed seedlings from emerging, while Penoxsulam offers systemic, "burn-down" action on already emerged small weeds.
Low Toxicity to Non-Target Organisms: When used at recommended rates, the formulation is designed to be relatively safe to crops while targeting weeds precisely.
Superior Weed Control for Rice Fields
Penoxsulam 1% + Pendimethalin 24% SE delivers robust performance against tough weeds including grasses, broadleaf weeds, and sedges that commonly hamper rice growth. Thanks to its dual active ingredients, this herbicide blocks weed germination and growth at the critical pre- and early post-emergence stages, ensuring better crop establishment and yield.
Easy Application and Compatibility
This herbicide comes as a user-friendly, water-dispersible suspension emulsion. The solution is easy to measure, mix, and spray using standard agricultural sprayers. Furthermore, it exhibits compatibility with most agrochemicals, allowing integrated weed management programs without complications.
Safe Storage and Handling
Packaged in sturdy HDPE bottles or cans, the product should be stored in cool, dry, and well-ventilated environments to maintain quality and efficacy. With a mild aromatic smell and yellowish to brown color, it offers safe usage when label precautions are followed, thanks to its low to moderate toxicity profile.
FAQ's of Penoxsulam 1% + Pendimethalin 24% SE:
Q: How should Penoxsulam 1% + Pendimethalin 24% SE be applied for effective weed control in rice?
A: Apply Penoxsulam 1% + Pendimethalin 24% SE as a spray during pre- or early post-emergence stages using water as the carrier. Use appropriate spray equipment to achieve even coverage for best results.
Q: What are the main benefits of using this herbicide in rice farming?
A: The combination provides broad-spectrum control of grasses, broadleaf weeds, and sedges, promoting healthy rice crop establishment. Its selectivity and dual action help reduce weed competition, leading to increased yields.
Q: When is the optimal timing for application in rice fields?
A: The ideal application time is immediately after sowing or transplanting (pre-emergence), or soon after weed emergence (early post-emergence), to intercept and manage weeds before they impact rice growth.
Q: Is this Suspension Emulsion compatible with other crop protection products?
A: Yes, Penoxsulam 1% + Pendimethalin 24% SE is compatible with most commonly used agrochemicals, enabling it to be safely tank-mixed for comprehensive crop protection programs.
Q: How should the product be stored to ensure its effectiveness?
A: Store the herbicide in a cool, dry, and well-ventilated area, away from direct sunlight and extreme temperatures. Proper storage preserves its two-year shelf life from the manufacturing date.
Q: What safety precautions should be followed during handling and application?
A: Wear protective equipment, avoid inhalation and direct skin contact, and adhere to all label safety instructions, as it has low to moderate toxicity. Dispose of containers responsibly after use.
