In 1901, Peru's cotton industry suffered because of a fungus plague caused by a plant disease known as "Cotton wilt" and " "Fusarium wilt" (Fusarium vasinfectum).[8] The plant disease, which spread throughout Peru, entered the plant by its roots and worked it's way up the stem until the plant was completely dried up. Fermín Tangüis a Puerto Rican agriculturist who lived in Peru, studied some species of the plant that were affected by the disease to a lesser extent and experimented in germination with the seeds of various cotton plants. In 1911, after 10 years of experimenting and failures, Tangüis was able to develop a seed which produced a superior cotton plant resistant to the disease. The seeds produced a plant that had a 40% longer (between 29 mm and 33 mm) and thicker fiber that did not break easily and required little water.[9] The Tangüis cotton, as it became known, is the variety which is preferred by the Peruvian national textile industry. It constituted 75 percent of all the Peruvian cotton production, both for domestic use and apparel exports. The Tangüis cotton crop was estimated at 225,000 bales that year
