Oxyfluorfen 23.5% EC is a widely used, high-performance selective contact herbicide designed to control annual broadleaf weeds and some grasses in agricultural settings. It works by inhibiting the protoporphyrinogen oxidase (PPO) enzyme, leading to cell membrane disruption and rapid desiccation of weeds, particularly in the presence of sunlight
Key Agricultural and Pesticide Benefits:
Broad-Spectrum & Dual Action: It acts as both a pre-emergence and early post-emergence herbicide, providing a "double-action" benefit by killing emerging seedlings and controlling young weeds (cotyledon to 2-leaf stage).
Long-Lasting Residual Control: It creates a stable, chemical barrier on the soil surface, offering 30-40 daysand sometimes up to 8 monthsof residual weed suppression, which reduces the need for frequent reapplication.
High Selectivity & Crop Safety: It is specifically designed to kill weeds while leaving crops unharmed when applied at recommended doses, making it the #1 choice for crops like onions, garlic, tea, groundnut, and potatoes.
Labor Efficiency: Significantly reduces the need for manual weeding, providing a cost-effective solution that can save substantial labor expenses (e.g., in onion farming).
Effectiveness in Low Moisture: It performs reliably even in low-moisture soil conditions.
Environmentally Considered: It has low mobility, meaning it binds tightly to soil particles, reducing the risk of leaching into groundwater.
Ideal for Integrated Weed Management (IWM): Its unique mode of action allows it to be used in rotation with other herbicides to prevent weed resistance.
Typical Crops and Target Weeds:
Crops: Onion, Tea, Potato, Groundnut, Direct Seeded Rice, Mint, Cotton, and various vegetable crops.
