Prosper 300 SC

Technical breakdown: Why Prosper 300 SC is a vineyard essential

The core of Prosper 300 SC is spiroxamine, a unique active ingredient belonging to the spiroketalamine class. Unlike traditional triazoles, this substance offers a different mode of action against Uncinula necator (powdery mildew), making it an indispensable tool for anti-resistance management programs. Its efficacy in disrupting ergosterol biosynthesis within fungal cells ensures that the pathogen is halted both in preventative and curative scenarios.

Dual-action technology: Systemic and contact efficiency

Prosper 300 SC delivers its performance through a balanced combination of two distinct technical advantages:

• Systemic penetration: Once applied, the compound is rapidly absorbed into the plant tissues, providing prolonged protection for new shoots and rapidly growing grape berries.
• Contact shielding: The suspension concentrate formulation ensures excellent adhesion to the leaf surface, creating an instant barrier that neutralizes fungal spores upon contact.

The formulation technology provides superior surface coverage, minimizing the risk of wash-off and ensuring uniform distribution of the active ingredient across the vineyard canopy. This reliability is backed by the manufacturing standards of leading producers, including Bayer AG (Germany), Excwold Technologies Ltd (UK), Imperial Chemical Logistics GmbH (Germany), Bayer SAS (France), and Schirm GmbH (Germany).

Usage Guidelines and Application Standards

To maximize the product's biological potential, professional growers should adhere to the following technical parameters:

• Application rate: 0.7–1.0 liters per hectare.
• Maximum frequency: Up to 3 applications per season.
• Pre-harvest interval (PHI): 30 days prior to harvest, ensuring residual limits remain within safety standards for high-quality produce.

By leveraging its contact-systemic properties, Prosper 300 SC offers a robust defense strategy that maintains grape health throughout the critical stages of the growth season, securing both yield volume and quality.
