Napoval, CS

Why Napoval, SC has become a standard for potato and grain protection

Combined systemic insecticides are now a necessity for any agronomist striving to maximize yield while minimizing costs. Napoval, SC by Alfa Smart Agro blends two potent active ingredients: imidacloprid and alpha-cypermethrin. This combination strikes pests on two fronts simultaneously: through contact and systemic action.

The secret of the product's effectiveness

• Instant impact (knockdown effect): Alpha-cypermethrin affects the pest's nervous system upon the first contact, halting their feeding within minutes.
• Extended protection: Imidacloprid penetrates the plant and moves through the vascular system. New growth remains protected against aphids, thrips, and the Colorado potato beetle for 2–3 weeks.

Unlike single-component products, Napoval effectively mitigates pest resistance. If the Colorado potato beetle has already developed tolerance to pyrethroids, the systemic component leaves it no chance for survival. It is the optimal solution for farms seeking a balance between aggressive population reduction and long-lasting protection.

Technical aspects of application

The product is formulated as a suspension concentrate. This form adheres better to the leaf surface, reducing the risk of being washed away by rain. With a dosage of 0.15–0.2 L/ha, you get a reliable shield against pests of wheat (cereal leaf beetle, sunn pest) and potatoes. It is critical to keep the hazard class (2) in mind—strictly follow safety protocols and perform the final application 20–30 days before harvest.

Production facilities under Nanjing Red Sun, Shanghai Bioagriland Crop Care, and Shandong Sino-Agri United Biotechnology ensure consistent quality of active ingredients, making this insecticide a predictable and reliable tool for field management.
