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".

A distilled drink or liquor is an alcoholic drink produced by distilling (i.e., concentrating by distillation) ethanol produced by means of fermenting grain, fruit, or vegetables. Unsweetened, distilled, alcoholic drinks that have an alcohol content of at least 20% ABV are called "spirits". For the most common distilled drinks, such as whiskey and vodka, the alcohol content is around 40%. The term "hard liquor" is used in North America to distinguish distilled drinks
