Curzat R

Professional crop protection: The power of Corteva’s Kurzat R

Kurzat R is a time-tested combined fungicide that maintains its market position through the powerful synergy of cymoxanil and copper oxychloride. Unlike single-action products, this Corteva solution offers both systemic-local and contact properties, making it an essential tool for managing late blight, downy mildew, and early blight in vegetable production.

Why choose Kurzat R?

• Superior control over hidden infections: Thanks to cymoxanil's ability to rapidly penetrate plant tissues, the product can stop disease progression even within the first few hours after infection.
• Resistance management: The combination of active ingredients makes it significantly harder for fungal pathogens to develop resistance.
• Dual-action efficacy: Copper provides an immediate contact barrier on the leaf surface, while cymoxanil travels within the leaf to protect new growth.

Application and efficiency

Formulated as a wettable powder, Kurzat R is designed for easy mixing and stable preparation of the spray solution. The application rate ranges from 2.0 to 3.0 kg/ha, depending on the severity of the infection and the crop type. Growers can apply the product up to three times per season. As a Class 3 hazard product, it requires standard protective measures during handling. With a pre-harvest interval of 5 to 20 days, it is well-suited for structured crop management programs.

Who is this for? Kurzat R is the optimal choice for commercial farmers growing potatoes or cucumbers in high-humidity climates where the pressure of fungal diseases is constant. Its ability to redistribute on the leaf surface ensures high performance even if spray coverage isn't perfect, making it a reliable workhorse for any seasonal protection plan.
