• Residual Protection: Prevents weed regrowth by maintaining soil activity after application.
• Safe on Crops: Proven crop safety across multiple vegetables and cereals when applied as recommended.
• Efficient Formulation: Suspension Concentrate (SC) ensures easy mixing and uniform coverage.
• Enhanced Crop Yield: Reduces early weed pressure for better crop growth and nutrient uptake.

Composition

• Formulation Type: Suspension Concentrate (SC)
• Active Ingredient: Linuron 450g/L
• Product Type: Selective Broad-Spectrum Pre-Emergence and Pre-Transplant Herbicide
• Available Packs: 50ml, 100ml, 250ml, 1L, 20L

Mode of Action

Linuron inhibits photosynthesis by blocking the action of photosystem II, disrupting the transfer of high-energy electrons needed for converting water and carbon dioxide into oxygen and sugars. This blockage causes weed desiccation and death shortly after germination.

• Foliar Activity: Absorbed through weed leaves to kill emerged seedlings.
• Residual Activity: Penetrates the soil to stop new weeds from sprouting.
• Dual Control: Prevents both existing and germinating weeds, ensuring complete coverage.

Target Crops

• Carrots
• French Beans
• Onions
• Baby Corn
• Potatoes, Soybeans, Sweet Corn, and Maize (extended registrations)

Target Weeds

• Annual broadleaf weeds
• Grassy weeds
• Perennial broadleaf weeds (with extended use)

Application Recommendations

General Guidelines

• Apply to a well-prepared, weed-free seedbed before weed emergence.
• Ensure soil is moist for optimal absorption and residual action.
• Use clean water and calibrated spraying equipment for even distribution.

Crop-Specific Application

• Carrots – Pre-Emergence: Apply 1–2 days after sowing when the seed is at least 1.25 cm deep in fine soil.
• Carrots – Post-Emergence: Apply only after the 4-leaf stage; best results when weeds are under 50 mm tall.
• French Beans & Baby Corn – Pre-Emergence: Spray immediately or within one day after sowing. Seeds should be at least 2.5 cm deep and soil moist.
• Onions – Pre-Transplant: Apply one day before transplanting seedlings.

Application Rate

Apply at the rate of 1.0 L/ha (equivalent to 50ml in 20L of water) using 400L water per hectare.
