Katran

Reliable Defense Against Downy Mildew

Viticulture demands precision when it comes to plant protection. Downy mildew (plasmopara viticola) remains one of the most destructive threats to vineyard yields. «Katran», produced by Sinochem Hebei Corporation, offers a robust solution by utilizing a dual-action mechanism that combines systemic and contact properties.

Unlike single-mode fungicides, the strength of Katran lies in its active ingredients: Mancozeb and Metalaxyl. Mancozeb acts as a protective shield on the leaf surface, preventing spore germination, while Metalaxyl is absorbed systemically, providing curative protection for the inner tissues and new growth. This synergy is exactly what growers need to manage infection pressure in humid conditions.

Key Specifications and Application Guidance

• Formulation: Wettable powder, which ensures easy mixing and stable suspension in the spray tank.
• Usage Rate: 2.0–3.0 kg/ha. This allows for dose adjustment based on the disease severity in the vineyard.
• Safety and Timing: With a 30-day pre-harvest interval and a limit of 3 applications per season, Katran is best suited for the active growth phases, ensuring high efficacy without compromising the safety of the final product.

It is important to note that Katran falls under the 3rd hazard class, necessitating the use of personal protective equipment during application. For vineyard managers, this product represents a cost-effective, high-reliability choice for standard fungicide programs. By strictly following the 30-day waiting period, growers can ensure maximum protection while meeting food safety standards. Katran is the go-to tool for those who prioritize proven chemical stability over experimental solutions.
