Oxigard EC, KE

Technical Potential of Oxygard EC

"Oxygard EC" is based on oxyfluorfen, a diphenyl ether that fundamentally changes the strategy of weed control during early vegetative stages. Unlike systemic agents, this herbicide operates as a contact agent, creating a persistent protective "screen" in the topsoil layer.

Mechanism of Action and Selectivity

The active ingredient inhibits the protoporphyrinogen oxidase (PPO) enzyme in weed seedling tissues. The practical value of this approach lies in the fact that upon contact with the herbicide barrier, weed cells are destroyed under light exposure, resulting in immediate and irreversible desiccation. Due to its selective nature, the product effectively suppresses the development of annual broad-leaved and certain grass weeds without harming crops such as bulb onions or sunflowers.

Application Features and Performance

• Soil Activity: Due to its formulation as an emulsifiable concentrate, the active ingredient distributes uniformly within the soil substrate, maintaining activity even under varying moisture conditions.
• Contact Protection: When applied pre-emergence, Oxygard EC forms a protective film that weed sprouts cannot penetrate.
• Technological Flexibility: The herbicide integrates perfectly into onion and sunflower protection protocols, acting as a robust "soil barrier" against the initial flush of weeds.

Using Oxygard EC allows agronomists to minimize weed-crop competition during the critical "starting" phase, which directly influences crop stand density and final yield. Classified as Hazard Class 3, the product requires standard safety measures during handling, but its high selectivity justifies precise application.
