Citadel 25 OD

Advanced weed control technology

"Citadel 25 OD" by Dow AgroSciences is a specialized systemic herbicide engineered for high-performance weed management in rice and sorghum crops. The active ingredient, penoxsulam, belongs to the triazolopyrimidine sulfonamide class and functions by inhibiting the acetolactate synthase (ALS) enzyme in target weeds, which is crucial for protein synthesis and plant growth.

Formulation advantages: The OD edge

The core of "Citadel 25 OD" performance lies in its formulation as an Oil Dispersion (OD). This technical choice provides significant agronomic advantages compared to standard emulsifiable concentrates:

• Superior leaf adhesion: The oil-based carrier ensures the droplets anchor firmly to the leaf surface, preventing runoff even during variable weather.
• Enhanced penetration: The formulation aids the active ingredient in bypassing the leaf's waxy cuticle, allowing for rapid translocation into the weed's vascular system.
• Solution stability: The dispersion maintains a homogeneous mixture in the spray tank, ensuring consistent coverage across the field.

Operational precision

As a selective post-emergence herbicide, "Citadel" allows for targeted application based on actual infestation levels. Its systemic nature ensures that the chemical reaches all parts of the weed, halting growth almost immediately after contact.

Key technical specifications:

• Application rate: Ranges from 0.5 to 1.0 L/ha for typical weed pressures, with higher rates exceeding 3.0 L/ha allowed for specialized cases.
• Treatment frequency: Limited to 1 application per season, necessitating careful timing relative to weed development stages.
• Hazard classification: Classified as Class 3, requiring standard safety protocols for handling hazardous agricultural chemicals.

By leveraging systemic action and advanced OD formulation, this herbicide ensures crop safety for rice and sorghum while maintaining long-term field cleanliness, representing the standard in modern selective chemical protection.
