Synergy of Growth Regulation and Protection: Technical Overview of Gravis

Successful winter rapeseed production relies heavily on controlling plant architecture and managing pathogen pressure. Gravis by Alfa Smart Agro is a high-tech, two-component suspension concentrate that integrates growth regulation with potent fungicidal activity.

Key Components and Mechanism

• Mepiquat-chloride: A systemic plant growth regulator (PGR) that inhibits gibberellin synthesis. In practice, this prevents winter rapeseed from overgrowing, stimulates robust root system development, and ensures the growing point remains low, which is essential for cold hardiness.
• Tebuconazole: A triazole fungicide. Its role is dual: while providing systemic protection against fungal pathogens, it also exhibits growth-regulating properties, reinforcing the effect of mepiquat-chloride and promoting the thickening of the root collar.

Pathogen Control

Gravis effectively manages Alternaria, Sclerotinia, Phoma, and Cylindrosporium. Through systemic distribution within plant tissues, the product does not merely create a protective surface barrier but blocks mycelium development within the stems and leaves. By following a scheme of up to 2 applications per season, farmers can significantly reduce the risk of crop lodging and yield losses during harvest.

Application Details

To achieve optimal results, the product is applied via spraying with a dosage ranging from 0.6 to 1.2 liters per hectare, depending on the growth stage and disease pressure. As a class 2 hazard substance, it requires strict adherence to safety protocols. The stability of the suspension concentrate ensures a uniform working solution, which is critical for consistent active ingredient coverage across the entire leaf surface.
