Goiás state is once again the largest sunflower producer in Brazil, accounting for approximately 70% of the country's production. The 2024/2025 harvest is predicted to see an increase of 58.8% compared to the previous cycle, producing 71,000 tons. This success is due to a combination of natural factors, technology use, and strong sanitary defense work by the Goiás Agricultural Defense Agency (Agrodefesa). Sunflower cultivation in Goiás is crucial for oil extraction and animal feed, and is valued for its adaptability and good agronomic performance. However, the lack of selective herbicides for sunflower crops is a phytosanitary problem, as volunteer soybean plants can serve as hosts for pests like Asian rust. To maintain control of Asian rust, Agrodefesa establishes a specific sowing calendar, monitors planted areas, and implements rapid control actions.
