Agave tequilana Through the 1990s, diseases spread, particularly "Fusarium" fungi and "Erwinia" bacteria, exacerbated by the low genetic diversity of the agave plants. Other problems include the agave weevil, "Scyphophorus acupunctatus", and a fungus, "Thielaviopsis paradoxa". According to a 2004 study, additional pathogens, "Erwinia carotovora", "Enterobacter agglomerans", "Pseudomonas mendocina", and "Serratia" spp. are responsible for continued rot. The homoisoflavanones 5,7-dihydroxy-3-(4-methoxybenzyl)-chroman-4-one, 7-hydroxy-3-(4-hydroxybenzyl)-chroman-4-one and 4’-demethyl-3,9-dihydro-punctatin can be isolated from "A. tequilana". Agave tequilana Agave tequilana, commonly called blue agave () or tequila agave, is an agave plant that is an important economic product of Jalisco, Mexico, due to its role as the base ingredient
Agave decipiens Agave decipiens Agave decipiens, common names False Sisal or Florida agave, is a plant species endemic to coastal Florida though cultivated as an ornamental in other regions. The species is reported naturalized in Spain, India, Pakistan, and South Africa. Some authors have suggested that material from Central America and from the Yucatán Peninsula in Mexico might be of the same species as "A. decipiens." Gentry and Zona, however, discounted this possibility, regarding this non-Floridian material as "A. vivipara" (= "A. angustifolia") "Agave decipiens" grows on hummocks in the Everglades and other marshy areas very close to sea level. It is
