ESTRATÉGIAS DE CONTROLE DA FERRUGEM ASIÁTICA NA CULTURA DA SOJA

Abstract

Brazil is one of the largest soybean producers in the world, but several factors have hindered its production, mainly diseases caused by fungi that can cause losses of up to 90% in productivity. Among them, Asian rust caused by the fungus Phakopsora pachyrhizi stands out, which is difficult to control, since the pathogen forms ureodes that are easily disseminated, contaminating soybean plants during the harvest period, and the reduction of sensitivity from the fungus to fungicides has led producers to adopt the integrated management method for its control. Therefore, this work aims to present a synthesis of management strategies for the control of Asian rust in soybeans, such as cultural and chemical management and genetic control. The reduced sensitivity of the fungus to fungicides has led researchers to select sources of resistance for the development of new cultivars resistant to the disease, as well as the use of chemical control to control the disease in the crop and avoid losses of up to 90% of the crop. Cultural management with non-host species of Asian rust is an alternative for its control.
