Disease
As agave production has moved to an industrial scale since the end of 1980s, diseases and pests, collectively referred to as TMA (tristeza y muerte de agave, "wilting and death of agave"), have hit the crops. 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.

Famous quotes containing the word disease:
“And this disease that was Swann’s love had so multiplied, it was so intimately tied to all of Swann’s habits, to all his acts, to his thoughts, to his health, to his sleep, to his life, even to what he desired for his afterlife, his love was so much a part of him that it could not be extracted from him without destroying him entirely: as is said in surgery, his love was inoperable.”
—Marcel Proust (1871–1922)
“Anti-Semitism is a horrible disease from which nobody is immune, and it has a kind of evil fascination that makes an enlightened person draw near the source of infection, supposedly in a scientific spirit, but really to sniff the vapors and dally with the possibility.”
—Mary McCarthy (1912–1989)
“The artistic temperament is a disease that affects amateurs.... Artists of a large and wholesome vitality get rid of their art easily, as they breathe easily or perspire easily. But in artists of less force, the thing becomes a pressure, and produces a definite pain, which is called the artistic temperament.”
—Gilbert Keith Chesterton (1874–1936)
