FLORES LOPEZ, Hugo Ernesto et al. Effect of climate change on risk areas by wilting in Agave tequilana Weber Blue variety in Jalisco. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.spe13, pp.2497-2510. ISSN 2007-0934.

Tequila agave is the raw material for tequila, produced in the area of appellation of origin of tequila (DOT), comprising the state of Jalisco and some municipalities in the states of Nayarit, Guanajuato, Michoacan and Tamaulipas. Agave wilt caused by Fusarium oxysporum is one of phytosanitary problems facing producer in DOT, which persists today. The aim of this study was to evaluate the effect of climate change in Jalisco on tequila agave wilt based on the use of bioclimatic indexes. Monitoring information from fields with tequila agave from 1997-1998 and 2008-2009, generated to identify areas at risk by wilting (ZRM) and associated with the weather from 1961 to 1995 and 1961 to 2008 was used. It involved temperature, soil moisture and duration of moisture conditions that could favor wilt cycles in agave. The results showed relationship between ZRM with bioclimatic indices from the monitoring of agave in 1997-1998 and 2008-2009. 23.3% of the area increased their risk level, 50.5% of the area was unchanged and 26.2% of the area reduced their risk level. This result represents the effect of climate change on ZRM in Jalisco, but you need to use future climate change scenarios to project the trend of these changes in areas at risk by fusarium in DOT to produce tequila agave.
