Summary of Nova anomalia na cultura da soja: podridão das vagens em sistemas de produção

00:00:00 - 00:10:00

In the YouTube video "Nova anomalia na cultura da soja: podridão das vagens em sistemas de produção," researchers investigated the causes of soybean pod rot, which significantly impacts productivity and grain value. The project, led by Embrapa Agricola Pastoral, involved multiple institutions and disciplines. Studies on seeding time, cultivars, and fungicides showed no significant impact on disease incidence or grain damage, but higher fungal infections were observed in Integrated Agriculture and Livestock Production System (ILP) and Direct Seeding System (SPD) due to rainfall during harvest. Seed treatments and fungicides, particularly those containing carboxamides, were effective in controlling foliar diseases and grain damage. Four fungal isolates were identified, but their role in causing pod rot remains unclear. The researchers also explored the possible link between temperature anomalies and pod rot, with ongoing studies to confirm the correlation. The importance of choosing the right cultivar and effective fungicides was emphasized, and future efforts include ongoing research projects and the involvement of female researchers and students in rural technology development.

• 00:00:00 In this section of the YouTube video titled "Nova anomalia na cultura da soja: podridão das vagens em sistemas de produção," researchers studied the biological and abiotic factors contributing to the etiology of soybean pod rot. This issue, which affects the lower third of soybean plants near maturity, results in significant losses of productivity and grain value. The project, led by Embrapa Agricola Pastoral, is a multi-institutional and multidisciplinary collaboration involving the Foundation Mato Grosso, Embrapa Soja, Fundação Rio Verde, Epr Consultoria, and Universidade Federal do Mato Grosso. The researchers conducted studies on seeding time and cultivars, observing variations in disease intensity and grain damage. They also evaluated the effects of fungicides on foliar diseases and grain aversion, finding no significant impact on disease incidence or grain damage. Additionally, they assessed diseases in different planting systems, including integrated crop-livestock-forestry, integrated planting, and direct planting. The findings from these studies will contribute to the development of effective strategies for managing soybean pod rot.
• 00:05:00 In this section of the YouTube video titled "Nova anomalia na cultura da soja: podridão das vagens em sistemas de produção," the researchers report on their findings regarding the causes of increased pod rot in soybean crops in certain production systems. They note that there was no significant difference in disease incidence or percentage of damaged grains between the various production systems. However, they observed a higher occurrence of fungal infections in the Integrated Agriculture and Livestock Production System (ILP) and the Direct Seeding System (SPD). This is likely due to the environmental conditions during harvest, as these systems are located in the municipality of Sorriso, where there was a higher incidence of rainfall during that time. Another study focused on the effect of seed treatment and fungicides, specifically those based on carboxamides. The researchers found no difference in the percentage of damaged grains between the treatments. However, they did observe a better performance of foliar fungicides, particularly those containing carboxamides, in controlling foliar diseases and grain damage. The researchers also conducted isolations from affected vags and identified four fungal isolates that were pathogenic to soybean culture. However, they were unable to reproduce the symptoms of pod rot in the lab, suggesting that these isolates may not be the primary cause of the problem. The researchers also conducted studies on the climate anomalies leading up to the occurrence of pod rot and found a trend of increasing temperatures from year to year. While they have not yet been able to correlate this temperature anomaly with the occurrence of pod rot, further studies are being conducted to explore the possible climatic causes of this issue. Overall, the study provides valuable information for the agricultural sector, including the importance of choosing the right cultivar and the effectiveness of certain fungicides.
• 00:10:00 In this section of the YouTube video titled "Nova anomalia na cultura da soja: podridão das vagens em sistemas de produção," the speaker discusses the use of fungicides for foliar diseases in soybean production. While these fungicides have a beneficial effect on managing the disease, the optimal application time is still under study. Important findings regarding the grain and seed decay issue are being shared at events like Campo Simpos and congresses, with Embrapa set to disseminate the results through research and technical bulletins. Future steps to improve the management of this disease and reduce costs for farmers include ongoing research projects and the participation of female researchers and students in the development of rural technologies, which is crucial for challenging gender-related paradigms. The speaker expresses gratitude to various organizations and individuals for their financial and collaborative support.
