Efficacy of different chemical control strategies against Asian soybean rust
Keywords:
Phakopsora pachyrhizi; severidade; coletor de esporos; vulnerabilidade climática, aplicações curativasAbstract
This study aimed to compare different decision-making tools for adopting chemical control in Asian soybean rust management. For this purpose, experiments were carried out during the 2022/23 and 2023/24 crop seasons, using the following decision-making strategies: preventive fungicides applications, spore monitoring, climate vulnerability system (Agroconnect Platform), and curative fungicide applications based on field observations of symptoms. The results highlighted the importance of fungicide applications, especially as preventive measures, as an effective and reliable method to protect soybean plants against Asian soybean rust. These strategies promoted greater production stability in the production systems and enhanced farmers’ profitability.
