About Penoxsulam 2.67% OD
Penoxsulam 2.67% Oil Dispersion (OD) is a highly effective, selective, and systemic post-emergence herbicide primarily used in agriculture to control a broad spectrum of weeds in transplanted, direct-seeded, and water-seeded rice cultivation. It is a triazolopyrimidine sulfonamide herbicide that acts by inhibiting the acetolactate synthase (ALS) enzyme in weeds, leading to growth disruption and death within 2-4 weeks.
Agriculture and Pesticide Benefits
Broad-Spectrum Weed Control: Effectively manages grasses, broadleaf weeds, and sedges in rice fields, including Echinochloa spp. (barnyard grass), annual sedges, Leptochloa, and broadleaf weeds such as Heteranthera limosa and Monochoria vaginalis.
Systemic Action & Long Residual Effect: Absorbed by both leaves and roots and translocated throughout the plant (phloem and xylem), offering long-lasting residual control for 3060 days with a single application.
Superior Formulation (OD): The 2.67% Oil Dispersion (OD) formulation provides better foliar uptake, superior rainfastness (within 1 hour), and enhanced spray retention compared to other formulations.
High Crop Safety: When used as directed, it offers high selectivity and safety for rice crops, allowing them to thrive without competition.
Wide Application Window: It can be applied early post-emergence, from 5-7 days after transplanting (DAT) up to the early post-emergence stage in direct-seeded rice.
Controls Resistant Weeds: Effective against weed biotypes that are resistant to other commonly used herbicides (e.g., bensulfuron-methyl)
Description and Application Guidelines
Active Ingredient: Penoxsulam (CAS NO: 219714-96-2).
Formulation: 2.67% w/w OD (Oil Dispersion).
Application Timing: Typically 515 days after transplanting or 3-5 leaf stage of weeds.
Dosage: Approximately 75-100 mL per hectare (or as recommended on the local product label).
Mode of Action: ALS (Acetolactate Synthase) Inhibitor

Penoxsulam 2.67% OD delivers consistent and targeted weed elimination. Its selective action safeguards rice crops while eradicating broad-leaved weeds, sedges, and select grassy weeds. This systemic, post-emergence formulation works swiftly, ensuring healthier crop growth and optimal yields throughout the season.
User-Friendly Application and Compatibility
Designed as a liquid oil dispersion, this herbicide is straightforward to mix and apply. Compatible with most commonly used insecticides and fungicides, Penoxsulam 2.67% OD can be conveniently included in integrated pest and weed management programs for rice fields, saving time and effort.
Safe Storage and Environmental Considerations
Penoxsulam 2.67% OD should be stored in a cool, dry location away from food and feed. With low toxicity to non-target organisms and a stable, odorless composition, it is suitable for agricultural environments that prioritize sustainability and safety.
FAQ's of Penoxsulam 2.67% OD:
Q: How should Penoxsulam 2.67% OD be applied in rice fields?
A: Penoxsulam 2.67% OD is applied as a foliar spray, diluted in 100-120 liters of water per acre. Use 40-60 ml of the product per acre and ensure even coverage of rice plants and surrounding weeds for optimal results.
Q: What types of weeds does Penoxsulam 2.67% OD control?
A: This herbicide provides effective post-emergence control of broad-leaved weeds, sedges, and some grassy weeds commonly found in rice paddies.
Q: When is the best time to apply Penoxsulam 2.67% OD?
A: Apply Penoxsulam 2.67% OD post-emergence, when weeds have emerged but are still young and actively growing. This ensures systemic absorption and maximizes weed control efficiency.
Q: Where should Penoxsulam 2.67% OD be stored after purchase?
A: Store the product in its original HDPE container in a cool, dry place, away from direct sunlight and separated from food or feed products to maintain its quality and safety.
Q: What are the advantages of using an oil dispersion (OD) formulation?
A: The OD formulation enhances the product's spreading and absorption on weed foliage, increasing efficacy, reducing runoff, and improving compatibility with other agrochemicals used in the field.
Q: Is Penoxsulam 2.67% OD safe for rice crops and the environment?
A: Yes, this product is selective for rice crops and exhibits low toxicity to mammals, birds, and aquatic organisms. Always follow the recommended application guidelines to minimize potential environmental impact.
