Features of Oxyfluorfen
- Highly Effective: Oxyfluorfen can rapidly penetrate plant tissues, inhibiting the growth of buds, leaves, and roots, thereby achieving a weeding effect.
- Low Toxicity: Oxyfluorfen herbicide exhibits high selectivity towards target plants and does not cause significant harm to non-target plants, making it advantageous due to its low residue and low toxicity.
- Broad Spectrum: Oxyfluorfen herbicide is effective in controlling a variety of grass and some broadleaf weeds.

Application
Oxyfluorfen is a low-toxicity, contact herbicide that exhibits its herbicidal activity under light conditions. It is most effective when applied pre-emergence and early post-emergence. It has a broad spectrum of control against germinating weeds, effectively eliminating broadleaf weeds, sedges, and barnyard grass, but it only suppresses perennial weeds. Target crops include transplanted rice, soybeans, corn, cotton, peanuts, sugarcane, vineyards, orchards, vegetable fields, and forest nurseries, where it can control both monocot and dicot weeds.
Oxyfluorfen belongs to the class of fluorinated diphenyl ethers and is a super low-dose selective, contact herbicide for pre- and post-emergence application. Weeds primarily absorb the herbicide through their coleoptiles and mesocotyls, leading to death. It is suitable for use in rice, soybeans, wheat, cotton, corn, oil palm, vegetables, and orchards, controlling broadleaf weeds and certain grass weeds, such as Commelina, barnyard grass, sedges, Raphanus sativus, Avena, and Datura. The application rate is 1 to 2 g of active ingredient per 100 m².
For example, 4 to 6 days after transplanting rice, when barnyard grass is at the seedling stage to the 1.5-leaf stage, apply 1.5 to 2.3 mL of 24% Oxyfluorfen emulsifiable concentrate per 100 m², evenly mixing it into the soil. A 0.5% granular formulation can also be used. For crops like soybeans and cotton, apply the herbicide after sowing but before seedling emergence, using 7.5 mL of 24% Oxyfluorfen emulsifiable concentrate per 100 m², and spray it evenly on the soil surface.
