Synex 4 L Herbicide - Residual Control of Triazine-Resistant Broadleaf and Grass Weeds

Synex 4 L Herbicide provides effective residual and contact control of annual broadleaf and grassy weeds, including those resistant to triazine-based products. Powered by linuron, the same active ingredient found in Lorox and numerous vegetable and soybean programs, Synex 4 L is a reliable tool for foundation weed control where resistance and early-season competition threaten yield potential.

Key Benefits

• Effective on triazine-resistant weeds - broad-spectrum control in soybean, asparagus, carrot, celery, and other crops.
• Residual and contact activity - delivers both pre-emergent and early post-emergent performance for longer protection.
• Flexible program fit - can be used alone or with other soil-applied or POST herbicides to enhance spectrum and resistance management.
• Crop safety and versatility - trusted urea-based chemistry with selectivity in labeled crops.
• Dependable performance - a cost-effective solution for cleaner rows and reduced early-season weed competition.
