Panorama histórico da ferrugem asiática (Phakopsora pachyrhizi) no Brasil

Abstract

The country of Brazil is the greatest power in the world in terms of exporting grains the state of Mato Grosso is the largest producer of soybeans in Brazil. In this environment of need for maximum production, monocultures allow new diseases to appear and cause damage to production. In 2001 the Asian Rust disease appeared, caused by the fungus Phakopsora pachyrhizi, responsible for financial losses throughout the country. In this work, a literature review was carried out, addressing aspects such as where the disease appeared, why it advanced quickly through geography, what was the damage, how much damage it caused, forms of control used and which are effective, factors contributed to resistance of the fungus, and effective fungicides. One of the most effective strategies for the control of the disease, but the control of Asian Rust requires a multidisciplinary approach for its effective control. Despite having caused many financial losses, it is currently possible to control, and the number of occurrences of the disease has been falling in recent years.
