Dicquat, w.r.k. (Dicquat, 150 g/l)

Mechanism of Action and Technical Specification

Diquat (150 g/L) is a high-performance contact desiccant that functions by disrupting photosynthesis within green plant tissues. Manufactured by Sunrise Chemicals Co. Ltd., this soluble concentrate formulation acts exclusively at the site of contact, causing rapid cellular membrane rupture without systemic translocation. This makes it a preferred choice for rapid crop maturity management.

Field Performance Factors

For soybean and sunflower producers, this product offers specific technical advantages during the harvest preparation phase:

• Harvest Optimization: Provides uniform desiccation across the field, allowing for a structured and efficient harvest schedule.
• Pathogen Control: By rapidly drying out stems and leaves, it effectively stunts the spread of late-season mold and fungal pathogens.
• Reduced Losses: Improved dry-down helps maintain seed quality and ensures lower moisture content, reducing secondary drying costs.

Because the herbicide acts through physical contact, the success of the application is strictly tied to coverage. The use of fine-droplet nozzles is highly recommended to achieve maximum penetration of the foliage. Any leaf area not reached by the chemical will remain active, which may affect the uniformity of the final harvest result.

Handling and Application Stability

The soluble concentrate formulation ensures the mixture remains stable, preventing equipment clogging and filter blockage, which is common with less refined formulations. Being a non-selective, broad-spectrum herbicide, precise application calibration is essential to prevent drift. Users must note the Class 2 hazard rating and adhere to strict safety protocols, including the use of appropriate personal protective equipment during the handling and spraying process.
