Estratégias de controle de phytophthora sojae na cultura da soja revisão de literatura sobre resistência genética e ocorrência da doença no Brasil e nos Estados Unidos

Abstract

Soybean cultivation is of great importance to Brazilian and global agribusiness; however, its productivity can be compromised by several diseases, including root rot caused by Phytophthora sojae. This study aimed to analyze, through a literature review, management methods, genetic control, and the main resistance genes used to control this pathogen, as well as to compare studies conducted in Brazil and the United States. The research is characterized as qualitative, descriptive, and exploratory, developed from a bibliographic review and comparative analysis of national and international scientific publications. The results demonstrated that genetic resistance represents one of the most efficient strategies for disease management, especially through the use of Rps genes. However, the genetic variability of the pathogen can compromise the durability of resistance over time. It is concluded that the use of genetic resistance is fundamental in the control of Phytophthora sojae, and continuous studies focused on the development of new sources of resistance are necessary.
