Flint Star 520 SC

Reliable orchard protection: using Flint Star 520 SC

When it comes to protecting apple orchards from disease complexes, efficacy is non-negotiable. Flint Star 520 SC is a combination fungicide that has proven itself in my practice as “heavy artillery” against scab, powdery mildew, and moniliosis. The main advantage of this product is its combination of systemic and contact modes of action, provided by the pyrimethanil and trifloxystrobin in its formulation. This synergy allows it not only to eliminate existing infection centers but also to create a reliable protective barrier on the leaf surface.

Operational features and application rates

When treating apple trees, it is crucial to follow the application rate of 0.5–0.75 l/ha. The product comes as a suspension concentrate, which significantly simplifies the preparation of the working solution: it mixes perfectly with water, does not clog sprayer nozzles, and requires no complex filtration. As a class 3 hazard product, it is important to follow standard safety measures — wearing personal protective equipment is essential, even though the product is convenient to handle.

• Systemic and contact action: a double strike against pathogens.
• Scheduling flexibility: up to 3 treatments per season with a 20-day pre-harvest interval.
• Stability: effective performance across a wide temperature range, which is critical for spring applications.

It is worth noting that Flint Star 520 SC is a tool designed for intensive fruit farming. When rotated properly with products from other chemical classes, it ensures fruit cleanliness and a healthy leaf canopy, which directly impacts the marketability of apples during storage.
