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".
