Coffee leaf rust is a parasitic fungus that can only reproduce in live leaves of coffee plants. This fungus is was introduced into Latin America from Africa and made its way to Mexico in 1981. Since it's introduction coffee rust has spread to all major coffee growing states in Mexico including Chiapas, Oaxaca, Veracruz and Puebla but has historically caused little to no damage to coffee plants. Nevertheless, recent changes in weather due to global climate change, perhaps acting in synergy with in-farm conditions (old or undernourished plants or farms with intensified production that has removed too much shade cover), appear to be facilitating the reproduction and spread of this fungus. In recent years, the leaves of infected coffee plants have been falling prematurely in greater and greater numbers, resulting in coffee beans that fail to adequately mature and lower coffee production overall. During the coffee harvest cycle of 2014-2015, coffee rust has reduced production by 30-40% on average in Mexico, causing economic losses of millones of dollars for the coffee sector. This program seeks to help coffee growers control this disease, first by providing them with information on the degree of risk of coffee rust infection based on climatic models that predict areas with conditions most favorable to the fungus, and second by providing a series of management recommendations tailored to the level of risk of each coffee farm.
