Grinfort Extra

Technical Insights into Gринфорт Екстра (Grinfort Extra)

Grinfort Extra is a specialized systemic herbicide designed for precision weed management in sunflower and maize crops. Based on the active ingredient Terbuthylazine (a triazine group compound), this product functions as a highly effective pre-emergence solution, targeting annual dicotyledonous and grass weeds.

Mechanics of Pre-emergence Control

The product acts as a selective soil herbicide. Its primary technical advantage lies in the formulation of a concentrated suspension, which ensures a homogenous, stable film across the topsoil. This film acts as an active barrier, absorbing into the root systems and emerging shoots of weed seeds, effectively disrupting their metabolic processes before they can compete with the primary crop for nutrients and moisture.

Application and Technical Specifications

• Formulation: Suspension concentrate (SC), designed for optimal solubility and ease of integration into standard spray equipment.
• Application Rate: 4–4.5 L/ha, calibrated for reliable performance in various soil conditions.
• Action Type: Systemic and selective, ensuring that the crop remains unaffected while the weed population is suppressed.
• Operational Guideline: Single application allowed per season, emphasizing the potency and residual effectiveness of the compound.
• Safety Profile: Classified as Hazard Class 3, requiring standard agricultural handling protocols.

The manufacturing pedigree of Grinfort Extra involves the collaboration between TRUSTCHEM (Nanjing, China), Shanghai MIO Chemical, and AgroMaxi (Ukraine). This international partnership ensures that the herbicide meets rigorous standards for agricultural chemical stability and field performance in diverse climatic conditions.
