SOYBEAN LEAF DISEASES AND PHYTOPATHOMETRY

The soybean crop is one of the most relevant in the world economy. Due to technological advances its production is expanding, and with it the action of pests and diseases, limiting productivity. Among the main soybean diseases are the foliar diseases caused by fungi, such as Asian soybean rust, cercospora leaf spot, brown spot, target spot, and powdery mildew, which cause the most significant damage. Integrated management is used to control these diseases. Epidemiology offers subsidies for the control of diseases in a rational manner, so it is important to know the pathogen, the host, and how the environment influences the interaction between them, as well as quantifying the result of this interaction.
