Over the centuries, many diseases and environmental changes have wiped out whole fields of crops; e.g., potato blight in the1800s, corn leaf blight 1900s, cherry trees in northern Colorado in the 1950s. In this example it was possible for breeders and farmers to return to growing the corn seed that was not susceptible to this fungus. *, *Interestingly, and your family, at risk. Commun Agric Appl Biol Sci. This may shed light on why early farmers chose to cultivate it. In the early 1960s a dwarf rice cultivar IR8, which had high yields, was non-lodging (lodging means that plants fall over when the stems collapse due to environmental conditions, disease or insect attack), and had good response to nitrogen was planted throughout Southeast and South Asia.
