Coffee rust affects crops inevitably

Coffee rust affects crops inevitably, therefore, protection and prevention against it are fundamental.

Coffee rust is caused by a species of fungus called Hemileia vastatrix and was detected in Mexico for the first time in 1981 within the region of Soconusco; however, nowadays it exists in virtually every productive region of the country.

In 2012 a new and more aggressive type of rust attacked every region, its contagion and vector of infection are still unknown. Despite all that, it is known that rain, wind, and insects along with animals can transport the fungus along great distances. Humans can contribute as well towards involuntary dispersion of the fungus, especially during the harvesting season.

Weak coffee varieties against coffee rust were used across the country’s productive regions until 2012, which helped the sickness spread quickly. However, today coffee-producing regions have made efforts towards renovating their coffee plant stocks with more resistant varieties against the pathogen.

Reports regarding the phytosanitary program against coffee rust say that 8,500 growers have benefitted from it directly in the main coffee producing states.
