Applications

Penoxsulam is a translocated herbicide that is absorbed through the stems, young shoots, and roots, and is transported through the xylem and phloem to the meristem, where it inhibits plant growth, causing chlorophyll loss in the growing point. After treatment, the tip of the shoot turns red and dies within 7-14 days, and the plant dies within 2-4 weeks. This herbicide is a strong inhibitor of acetyl coenzyme A synthetase, and the effect of the herbicide is slow, and it takes some time for the weeds to gradually die.
Penoxsulam is a broad-spectrum herbicide for rice fields, which can effectively control rice weeds (including rice weeds resistant to metribuzin, atrazine, and acetyl coenzyme A carboxylase), sesbania, and one-year-old cyperaceae weeds, and is effective against many broad-leaved weeds, such as Heteranthera limosa, Eclipta prostrata, Sesbania exaltata, Commelina diffusa, and Monochoria vaginalis. The residual effect can last for 30-60 days, and a single application can effectively control the entire season's weed damage. At the same time, it can also control weeds resistant to bensulfuron in rice fields, and has residual activity against many broad-leaved and cyperaceae weeds and rice weeds, making it the most versatile herbicide for rice fields.

Key Applications of Penoxsulam:

1. Rice Cultivation (Paddy Fields)

   • Controls weeds such as barnyardgrass (Echinochloa spp.), sedges (Cyperus spp.), and broadleaf weeds.

   • Applied in flooded or moist conditions for better efficacy.

   • Often used in combination with other herbicides (e.g., cyhalofop-butyl) for enhanced weed control.

2. Turf and Ornamental Grass Management

   • Used on golf courses, lawns, and sports fields to control invasive weeds.

   • Effective against annual bluegrass (Poa annua) and other grassy weeds.

3. Aquatic Weed Control

   • Applied in irrigation canals, ponds, and reservoirs to manage invasive aquatic weeds.

   • Helps prevent clogging and improves water flow.

4. Other Crops (Limited Use)

   • Some formulations are used in sugarcane and non-crop areas for weed suppression.

Mode of Action

• Inhibits acetolactate synthase (ALS), an enzyme essential for branched-chain amino acid (valine, leucine, isoleucine) synthesis in plants.

• Leads to growth inhibition and eventual death of susceptible weeds.

Advantages of Penoxsulam

• Selective control (safe for certain crops like rice when used correctly).

• Low application rates (highly effective at low doses).

• Long residual activity providing extended weed suppression.

Precautions & Limitations

• Resistance risk: Overuse can lead to ALS-resistant weeds.

• Water solubility: Requires proper management to avoid runoff into aquatic ecosystems.

• Crop sensitivity: Some rice varieties may show phytotoxicity if misapplied.

Common Trade Names

• Grasp® (for rice)

• Granite® (for turf)

• Prequel® (premix with other herbicides)

Penoxsulam is widely valued for its efficacy in rice paddies and turf management, making it a key tool in integrated weed management programs. Always follow label recommendations for safe and effective use.
