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 polianthiflora Agave polianthiflora Agave polianthiflora is a relatively small member of the genus Agave, in the subfamily Agavoideae, endemic to northern Mexico. The succulent is native to the States of Sinaloa, Chihuahua and Sonora. "Agave polianthiflora" produces a small basal leaf rosette of about in diameter. Leaves are narrow and lanceolate, with multiple white filaments protruding from their edges. Flowers are red and tubular, in length and narrow, unusual in the genus. The flower spike is tall. "Agave polianthiflora" is cultivated as an ornamental plant. It is mostly easily propagated from seed, as it does not offset as much as other
