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 mitis (2.4 inches) long. Agave mitis Agave mitis is a plant species native to the Mexican states of Hidalgo, Tamaulipas and San Luis Potosí, referred to as "Agave celsii" in many publications. "Agave mitis" forms rosettes of blue-green to yellow-green, fleshy leaves up to 60 cm (2 feet) long. The leaves have soft brown spines not nearly as imposing as those of other agaves. The flowering stalk is up to 2.5 m (8 feet)tall, with the flowers closely appressed against the stem forming a narrow column much more compact than most other species of the genus. Flowers are green, each up
