Profile
First marketed in 1976. Oxyfluorfen is primarily absorbed through the foliage and young shoots, with minimal uptake through the roots and limited movement within the plant. It works by inhibiting the enzyme protoporphyrinogen oxidase (PPO), leading to the build-up of light-sensitive porphyrins. When exposed to light, these compounds react with oxygen to produce reactive oxygen species that damage cell membranes through lipid peroxidation, ultimately causing the plant cells to break down and die.
Key Features & Benefits
- Pre- and Post-Emergent Action: Controls weeds both before and after germination for flexible application.
- Residual Control: Forms a protective layer in the soil, preventing new weeds from emerging for extended periods.
- Broad-Spectrum Activity: Effective against a wide range of broadleaf and some grassy weeds.
- Low Water Solubility: Minimises leaching, ideal for long-lasting action in stable conditions.
