en.Wedoany.com Reported - Gowan Company, LLC launched two new fungicides at the Hortitec horticultural exhibition in Brazil in June 2026—Harpon (zoxamide + cymoxanil) and Airone (copper oxychloride + copper hydroxide)—targeting vegetable and specialty crop growers, strengthening its product portfolio in the professional horticultural market.
Founded in 1963 and headquartered in Yuma, Arizona, USA, Gowan is a multinational company with over sixty years of experience in crop protection, operating across multiple agricultural markets worldwide. In recent years, it has been expanding its business in the Brazilian market. Harpon is a combination product with active ingredients zoxamide and cymoxanil, positioned as a preventive fungicide. Its mode of action inhibits spore release, interrupting the infection cycle before pathogen spread. Zoxamide has a unique mode of action, and rotation with active ingredients from different chemical classes supports resistance management strategies. This product has been registered for horticultural crops such as lettuce, onions, tomatoes, and potatoes.
Airone is a copper-based bactericide, combining two copper sources—copper oxychloride and copper hydroxide—and has been registered for use on multiple crops. Gowan specifically highlights its efficacy against blackleg in potatoes, one of the major challenges faced by potato growers. The combination of the two copper sources balances rapid action with residual effectiveness, disperses quickly in spray solutions, and demonstrates good tank-mix compatibility.
Gowan states that Harpon and Airone are designed to complement each other and can be integrated into comprehensive disease management systems. By combining preventive protection, multiple modes of action, and operational convenience, they help growers improve crop health. This exhibition reflects Gowan's continued focus on the horticultural market and its strategic direction of aligning technical solutions with growers' practical needs.
