OXEN GOLD 515EC is designed to address the significant reduction in productivity caused by annual grasses and broadleaf weeds in crops such as cotton and onions, particularly during the early stages of growth. These weeds compete aggressively with crops for essential resources including nutrients, moisture, and sunlight, thereby suppressing crop growth and establishment. As a result, crop yield and quality are adversely affected, while the cost of weed management increases. Failure to control these weeds in a timely and effective manner can lead to severe crop losses and reduced overall farm profitability.

Product Overview

OXEN GOLD 515EC is a post-emergence herbicide formulated for the control of annual grasses and broadleaf weeds in cotton and onions.

It contains three active ingredients:

1. Pendimethalin 175 g/L
2. Oxyfluorfen 40 g/L
3. Acetochlor 300 g/L

This combination provides effective and broad-spectrum weed control through multiple modes of action.

Mode of Action

OXEN GOLD 515EC combines three herbicidal mechanisms:

Acetochlor:

Acetochlor is a pre-emergence herbicide belonging to the chloroacetanilide group that inhibits key enzymes involved in lipid biosynthesis, including elongase and geranylgeranyl pyrophosphate (GGPP)-related pathways. By disrupting the formation of very long chain fatty acids and other essential components required for cell division and membrane development, it interferes with normal plant growth processes. This results in failure of cell elongation and division, ultimately preventing proper establishment of susceptible weeds.

Oxyfluorfen:

Oxyfluorfen is a contact herbicide that exerts its effect by inhibiting the enzyme protoporphyrinogen oxidase in the chlorophyll biosynthesis pathway. This inhibition leads to the accumulation of photodynamic compounds that, in the presence of light, generate reactive oxygen species. These highly reactive molecules cause lipid peroxidation of cell membranes, resulting in rapid membrane disruption, cellular leakage, tissue necrosis, and eventual plant death.

Pendimethalin:

Pendimethalin is a pre-emergence herbicide in the dinitroaniline group that inhibits cell division by interfering with microtubule assembly during mitosis. It prevents the formation of spindle fibers necessary for chromosome separation, thereby inhibiting root and shoot development in germinating weeds. As a result, susceptible plants fail to emerge or establish properly, leading to their eventual death.

This multi-site activity ensures effective control of susceptible weeds and improves overall efficacy.
