Protection to initial infection of agave wilt on Agave tequilana Weber var. azul using Trichoderma sp.

摘要：

Agave is the raw material to produce tequila, the most traditional Mexican alcoholic beverage. This crop takes six to eight years to get industrial maturity. Agave has been reproduced by centuries to new commercial plantations using small cloned plants that grownup adjacent to mother plants called hijuelos (lateral buds ), and recently by in vitro produced plantlets, low genetically variability is present. Agave wilt is a very important soil-borne disease in this crop and is caused by combined action of a vascular wilt induced by Fusarium oxysporum a stem rot induced by F. solani pathogenic stains. Now, an incidence average of 23％ of dead plants is very important, especially when low prices reduce the area of new plantations for future production. Chemical control is ineffective because cropland is rain fed and by the pathogen long incubation period of at least two years. In 2005 naturally grown agave root associated Trichodema spp. stains were sought in different commercial crops. Bar 331 and ZAP6-1M Trichoderma spp. strains shown an endorhizosphere colonization capacity superior to 90％ with good in vitro antagonistic ability against Fusarium oxysporum and F. solani pathogenic to agave.
