Systemic Rapeseed Protection: The Mechanism of «Viriy»

The effectiveness of pest control in winter rapeseed depends on the product's ability to penetrate plant tissues and maintain activity over time. The insecticide «Viriy» by Frandesa (Republic of Belarus) is based on the active ingredient thiacloprid, a neonicotinoid that provides profound systemic protection.

Technical Specifications

Thiacloprid targets the nicotinic acetylcholine receptors in the insect nervous system. Unlike many other neonicotinoids, this component offers an optimal balance of high absorption speed and moderate toxicity to warm-blooded animals (Hazard Class 3). The suspension concentrate formulation ensures that the active ingredient distributes evenly within the spray solution, forming a durable protective film on the leaf surface.

Application and Efficacy

• Systemic Action: The product is rapidly absorbed by plant tissues, meaning it becomes rainfast within hours of application.
• Target Spectrum: The primary targets are pests such as the rapeseed blossom beetle and cruciferous flea beetles.
• Regimen: The dosage of 0.2–0.3 L/ha is calibrated to suppress pest populations under high pressure. Up to 2 applications per season are permitted.
• Crop Safety: By adhering to the 30-day pre-harvest interval, «Viriy» minimizes residue levels in seeds, which is critical for rapeseed destined for export.

Using «Viriy» as part of an integrated crop management system ensures long-lasting protection, reducing the need for repeat insecticide applications during critical growth stages and minimizing the overall chemical load on the field.
