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

People either eat them raw or brew them into alcoholic beverages. The leaf bases are also edible, but require roasting to destroy unpleasant chemical compounds Agave shrevei Agave shrevei is a member of the family Asparagaceae, indigenous to the Sierra Madre Occidental in Mexico, along the boundary between the states of Chihuahua and Sonora.
