Vivaya Herbicide
Penoxsulam 1.02% + Cyhalofop-butyl 5.1% OD
Advanced Post-Emergence Weed Control for Paddy Fields
Vivaya Herbicide is a highly effective post-emergence rice herbicide formulated with the powerful combination of Penoxsulam 1.02% + Cyhalofop-butyl 5.1% OD (Oil Dispersion). This dual-action chemistry delivers broad-spectrum control of grasses, sedges, and broadleaf weeds that commonly reduce rice productivity.
The formulation combines the systemic ALS-inhibiting activity of Penoxsulam with the selective grass-killing action of Cyhalofop-butyl, allowing farmers to control multiple weed types with a single application. This synergy helps maintain clean fields during the most critical crop growth stages, resulting in improved nutrient utilization, healthier plant growth, and higher yields.
Vivaya Herbicide is widely recommended for transplanted and direct-seeded paddy due to its excellent crop safety, fast absorption, and long-lasting weed suppression.

Key Features and Benefits
Dual-Action Weed Control
The combination of Penoxsulam and Cyhalofop-butyl provides control over grassy weeds, sedges, and broadleaf weeds, ensuring cleaner paddy fields.
Systemic Weed Elimination
Both active ingredients are absorbed through leaves and move within the weed plant, stopping growth and eventually killing the weeds.
Broad Spectrum Performance
Effectively manages difficult weeds that often survive single-chemistry herbicides.
Early Season Crop Protection
Prevents weeds from competing with rice for nutrients, water, and sunlight during critical crop growth stages.
Excellent Crop Safety
Specifically designed for paddy cultivation with high selectivity and minimal crop stress.
Long-Lasting Control
Provides extended weed suppression, reducing the need for repeated applications.
Improved Yield Potential
Cleaner fields help the crop use nutrients efficiently, resulting in better tillering and higher grain yield.
Mode of Action
Penoxsulam works by inhibiting the ALS (Acetolactate Synthase) enzyme, which is essential for amino acid synthesis in weeds. This stops cell division and plant growth.
Cyhalofop-butyl inhibits the ACCase enzyme, which is responsible for fatty acid synthesis in grassy weeds. This disrupts membrane formation and causes weed death.
The combination ensures multiple biochemical pathways are blocked, making it highly effective against mixed weed populations.
