Grinfort DK 150, RK, (Dicquat, 150 g/l)

Optimizing Sunflower Harvest with Grinfort DK 150

Efficient sunflower harvesting depends largely on the uniformity of head maturation and grain moisture content. In the face of unpredictable autumn weather, chemical desiccation has become a standard agronomic practice. Grinfort DK 150, RK, based on Diquat (150 g/L) and produced by the Chinese manufacturer “Nanjing Essence Fine-Chemical Co. Ltd”, provides a practical solution for growers aiming to streamline the harvest process.

Mechanism and Efficacy

This product functions as a non-selective contact herbicide-desiccant. Unlike systemic pesticides, Diquat acts by rapidly disrupting cell membranes upon contact, causing immediate dehydration of plant tissues. For sunflower production, this means a significant acceleration of plant dry-down, suppression of secondary fungal infections, and the ability to schedule combine operations effectively.

• Active Ingredient: Diquat (150 g/L), renowned for its immediate impact on green plant mass.
• Formulation: Soluble Concentrate (RK), which ensures easy tank mixing and consistent spray patterns.
• Supply Chain: Represented in the market by Ukragrocom, ensuring product consistency and adherence to safety standards.

Application Guidelines

To maximize the performance of Grinfort DK 150, proper application is essential. The recommended application rate is 2–3 L/ha. Because it is a non-selective herbicide, drift management is critical to protecting adjacent fields. Key application parameters include:

• Application Frequency: Maximum 1 treatment per season.
• Pre-harvest Interval (PHI): 6–10 days, depending on environmental conditions and current moisture levels.
• Hazard Classification: Class 2, requiring standard protective equipment and safety protocols.

Grinfort DK 150 is a strategic tool for minimizing harvest losses and reducing subsequent drying costs, ensuring high-quality sunflower seeds even during challenging agricultural seasons.
