Perspectives on plant nutrition and soil fertility in rhizoctonia management in soybean
摘要
Rhizoctonia solani J. G. Kühn is an emerging concern in soybean production due to its broad host range, ease of dissemination, and persistence in soil as microsclerotia. Effective management strategies are challenging, requiring an integrated approach that includes genetic, biological, chemical, and cultural methods. Recent research has highlighted the importance of soil fertility and nutritional management in disease suppression. This review explores advances in understanding the etiology and epidemiology of R. solani in soybean, with a focus on novel management strategies. Emphasis is placed on the role of soil amendments, particularly liming, in modifying soil acidity, improving nutrient availability, and fostering suppressive soil conditions that limit pathogen proliferation. Additionally, the efficacy of biological control agents such as Trichoderma and Bacillus spp. is discussed, along with their interactions with soil microbiota. Advances in molecular tools, including CRISPR-based genome editing and high-throughput screening for resistant cultivars, offer new perspectives for genetic resistance development. Future research should prioritize integrating these strategies to enhance disease control under field conditions, addressing both biological efficacy and economic feasibility. By adopting a holistic approach that combines soil health management with biotechnological innovations, it is possible to mitigate losses caused by R. solani and improve soybean resilience to soilborne pathogens.
