Multiplex Pyrium 10 Herbicide - Bispyribac Sodium 10% SC for Paddy Weed Control

Multiplex Pyrium 10 is a post-emergent systemic herbicide formulated with Bispyribac Sodium 10% SC, designed specifically to control a wide range of grasses, sedges, and broadleaf weeds in paddy (rice) crops. Belonging to the pyrimidinyl thiobenzoate chemical group, this soluble concentrate (SC) formulation is absorbed by weeds and translocated throughout the plant, giving thorough and reliable weed control. It is a practical choice for farmers who want to keep their rice fields free from competitive weeds and protect crop health and yield.

Pyrium 10 works after weeds have emerged, making it a flexible option for both paddy nurseries and main fields. It targets common and damaging weeds such as Echinochloa crus-galli, Echinochloa colona, Ischaemum rugosum, Cyperus iria, Cyperus difformis, Fimbristylis miliacea, Ludwigia parviflora, and Monochoria vaginalis. By reducing weed competition, the product allows rice plants to grow and thrive, supporting healthier crops and better harvests. The recommended dosage is 2 to 3 ml per liter of water, applied uniformly over weed-infested areas.

This product is registered and approved for use in India under the Insecticides Act, 1968, giving farmers confidence in its regulatory compliance. It is easy to mix and apply with standard spray equipment, and its systemic action ensures that weeds are controlled from within, not just on the surface. Multiplex Pyrium 10 is a dependable, farmer-friendly herbicide for effective paddy weed management.

Key Benefits

• Broad-spectrum weed control: Effectively targets grasses, sedges, and broadleaf weeds in a single application, reducing the need for multiple products.
• Post-emergent action: Applied after weeds have emerged, so you can see the weeds and treat them directly for visible results.
• Systemic movement: Absorbed by weeds and carried throughout the plant, giving thorough control from roots to leaves.
• Versatile use: Suitable for both paddy nurseries and main fields, giving flexibility across your rice-growing stages.
• Improved crop health: Removes weed competition for water, nutrients, and sunlight, helping rice plants grow stronger and yield better.
• Easy to mix and apply: Soluble concentrate formulation mixes readily with water and spreads evenly with standard spray equipment.

How It Works

Multiplex Pyrium 10 contains Bispyribac Sodium, a post-emergent systemic herbicide. When sprayed on emerged weeds, the active ingredient is absorbed through the leaves and other green parts of the weed. Once inside, it moves systemically through the plant, reaching the growing points and roots. This translocation ensures that the herbicide acts throughout the weed, not just on the sprayed surface.

Bispyribac Sodium works by interfering with an important enzyme involved in the production of essential amino acids in the weed. Without these amino acids, the weed cannot carry out normal growth processes. The weed stops growing, shows visible damage, and eventually dies. Because the herbicide is systemic, even weeds that are only partially covered by the spray are affected, giving more complete control. This mode of action makes Pyrium 10 effective against a broad range of grasses, sedges, and broadleaf weeds commonly found in paddy fields.

Technical Specifications

Recommended Dosage & Application

Apply the solution uniformly over the weed-infested area after weed emergence. Use a flat-fan nozzle for even distribution and ensure thorough coverage of the weeds for optimal control. Apply during calm weather conditions to prevent spray drift.

When to Use

Multiplex Pyrium 10 should be applied after weeds have emerged in the paddy field. This is the key timing for this post-emergent herbicide, as it works on actively growing weeds. For best results, apply when weeds are young and actively growing, as they are more susceptible to the herbicide at this stage.

The product is suitable for use in both paddy nurseries and main fields, so you can plan applications according to your crop stage and weed pressure. Choose a calm day for spraying to avoid drift onto non-target areas. Avoid application during heavy rain or when rain is expected soon, as this can wash the product off the weeds before it is absorbed.

Step by Step Usage Instructions

1. Prepare the spray tank: Fill the spray tank halfway with clean water.
2. Add the herbicide: Add the recommended dosage of 2 to 3 ml of Multiplex Pyrium 10 per liter of water to the tank.
3. Mix thoroughly: Continue to fill the tank with water while stirring continuously. Ensure the solution is well mixed before application.
4. Apply the solution: Spray the solution uniformly over the weed-infested area after weed emergence. Use a flat-fan nozzle for even distribution.
5. Ensure full coverage: Make sure all weeds are thoroughly covered for optimal control.
6. Choose calm conditions: Apply during calm weather to prevent spray drift onto non-target areas.

Precautions & Safety

• Wear protective gear: Wear protective clothing, gloves, and eyewear while handling and applying the product.
• Protect water bodies: Avoid contamination of water bodies by disposing of the herbicide or its container properly.
• Store safely: Store in a cool, dry place away from direct sunlight and out of reach of children and animals.
• First aid: In case of contact with skin or eyes, rinse immediately with plenty of water. If swallowed, do not induce vomiting and seek medical attention immediately.
