Zorvek Vinabria

Next-Generation Technology in Mildew Control

Grape growers know that mildew control is not just about yield preservation; it is a battle for the survival of the plantation during humid weather. Zorvec Vinabria by Corteva offers a fundamentally different approach to crop protection, setting it apart from traditional contact or systemic fungicides.

The product is based on a combination of two active ingredients: oxathiapiprolin and folpet. Oxathiapiprolin, belonging to the piperidinyl-thiazole-isoxazoline class, targets the pathogen at a biochemical level by inhibiting sporangia formation and germination. Unlike many alternatives, it has a unique ability to bind to the leaf's waxy cuticle, ensuring rainfastness within just 20 minutes of application.

Why choose this fungicide?

• Translaminar protection: The product penetrates leaf tissues, protecting both the treated side and the underside of the leaf.
• New growth protection: Due to systemic redistribution, active components migrate into parts of the plant that emerge after the spraying event.
• Dual action: Folpet complements the efficacy of oxathiapiprolin, broadening the control spectrum and serving as a reliable barrier against primary infections.

Professional application insights

Precision is key. With a dosage rate ranging from 1.0 to 2.0 L/ha, timing according to the crop development stage is crucial. Maximum efficiency is achieved through preventative use, well before visible signs of infection appear. The limit of 2 applications per season is designed to mitigate the risk of pathogen resistance—a standard practice for oxathiapiprolin-based products.

Weaknesses: High sensitivity to spray coverage quality. The product does not forgive "gaps" during application, making the use of high-quality fine-mist spraying equipment essential.

This is the optimal solution for large-scale operations focused on producing high-quality grapes and tomatoes without the risk of quality loss from hidden infection reservoirs. With a 21-day pre-harvest interval, it fits seamlessly into intensive crop protection programs.
