Rubigan

Systemic Pathogen Control: How Rubigan Works

The core value of Rubigan, produced by Gowan Comércio Internacional e Serviços, lies in its active ingredient, fenarimol, a pyrimidine derivative. Unlike contact fungicides, fenarimol inhibits ergosterol biosynthesis within fungal cells. This biochemical process halts mycelial development at early stages, which is crucial for managing powdery mildew and scab in fruit and berry crops.

Technical Application Details

The product is formulated as an emulsifiable concentrate, ensuring rapid solubility and the creation of a stable spray solution. Its systemic action allows the components to penetrate plant tissues, protecting both treated surfaces and new growth. This makes Rubigan an effective tool for protection programs in strawberries, apples, pears, cherries, peaches, currants, and gooseberries.

• Application Rate: Up to 0.5 L/ha, making it a cost-effective solution for intensive orchard management.
• Limitations: A maximum of 2 applications per season, dictated by the metabolic profile of the active ingredient.
• Safety: Adhering to the 30-day pre-harvest interval ensures no residual levels in the final product.

Rubigan demonstrates high efficacy against a broad spectrum of leaf spots and scab. Its mechanism is based on interrupting the nutritional chain of the fungal organism, effectively preventing spore formation. Given its systemic nature, it is an essential component when first signs of powdery mildew or mosaic appear, providing a prolonged protective window.
