Korum 25 EC – AgPharma | Dual-Action Post-Emergence Herbicide for Rice Weed Control

Dual-Action Post-Emergence Herbicide for Complete Grass Weed Control in Rice

Weed competition is one of the major challenges in rice cultivation. Grassy weeds compete with rice plants for nutrients, water, sunlight, and space, reducing crop growth, tillering, and final grain yield. Effective weed control at the right stage is essential for achieving a clean rice field and better crop performance.

Korum 25 EC by AgPharma is an advanced post-emergence herbicide specially developed for the effective control of annual grassy weeds in rice. It contains a powerful dual combination of Cyhalofop-butyl 15% and Metamifop 10%, delivering rapid weed suppression, broad-spectrum grass weed control, and excellent crop safety.

Korum helps rice plants grow free from harmful weed competition, resulting in improved tillering, healthier crop development, and higher yield potential.

What is Korum 25 EC?

Korum 25 EC is a dual-action rice herbicide formulated as an Emulsifiable Concentrate (EC). It is recommended for use as a post-emergence spray in rice fields where grassy weeds are actively growing.

The product combines two strong ACCase-inhibiting active ingredients, making it an effective solution against common and difficult grass weeds found in transplanted rice and direct-seeded rice.

Active Ingredients

Korum 25 EC contains:

Cyhalofop-butyl: 15%
Metamifop: 10%
Formulation: Emulsifiable Concentrate (EC)

This dual-active formulation provides improved efficacy against grassy weeds and supports better weed resistance management in rice fields.

Key Benefits of Korum 25 EC

1. Excellent Control of Grassy Weeds in Rice

Korum 25 EC provides effective control of annual grassy weeds commonly found in rice fields. It helps reduce weed pressure and allows rice plants to grow with less competition.

2. Dual-Action Chemistry for Better Performance

The combination of Cyhalofop-butyl 15% and Metamifop 10% offers dual-action weed control. This improves herbicide performance and helps target difficult grass weeds more effectively.

3. Effective Against Difficult and Resistant Grass Weeds

Korum is an ideal tool for managing tough grassy weeds in rice. Its dual chemistry helps improve control where single-active herbicides may show reduced performance.

4. Rapid Weed Growth Suppression

After application, Korum is absorbed through weed foliage and moves inside the plant. It quickly stops weed growth, reducing further competition with the rice crop.

5. Safe for Transplanted and Direct-Seeded Rice

Korum 25 EC is suitable for both transplanted rice and direct-seeded rice (DSR) when used according to label recommendations.

6. Improves Crop Vigor and Tillering

By controlling grassy weeds, Korum helps rice plants access more nutrients, sunlight, water, and space. This supports better crop vigor, improved tillering, and stronger yield potential.

7. Supports Higher Grain Yield

Clean rice fields allow the crop to grow more efficiently. With reduced weed competition, rice plants can perform better and produce improved grain yield.

8. Useful for Herbicide Resistance Management

The dual combination of two ACCase-inhibiting herbicides makes Korum a valuable option in rice weed management programs, especially where difficult grassy weeds are a concern.

Mode of Action

Korum 25 EC combines Cyhalofop-butyl and Metamifop, both belonging to the ACCase inhibitor group of herbicides.

After spray application, the herbicide is absorbed through the foliage of actively growing grass weeds. It is then translocated to the growing points of the weed plant. At these growth points, Korum inhibits fatty acid synthesis, which is essential for weed growth and development.

As a result, weed growth stops, the plant weakens, and eventually the weed dies. This helps reduce weed competition and supports healthier rice crop growth.

Target Weeds

Korum 25 EC is effective against annual grassy weeds commonly found in rice fields, including:

• Swanki / Sawanki
• Echinochloa crus-galli
• Jungle Rice
• Echinochloa colona
• Barnyard Grass

• Other annual grassy weeds in rice fields

Recommended Crop

Korum 25 EC is recommended for:

• Transplanted Rice
