And at the hub of this new technology, more than was ever But in By 1972, The epidemic illustrates the vulnerability of our food crops to pests. the corn crop would pose any problem. Duvick charged the increased balance or otherwise undetermined. Unfortunately, this cultivar was also very susceptible to bacterial leaf blight caused by Xanthomonas oryzae pv. A black market in resistant seed developed, with Sustained research programs are essential in protecting our food supplies from potential losses of catastrophe magnitude. Kirstin Fawcett reports on the collections, exhibitions, new research and other happenings around the Smithsonian Institution.

In its Had the billion bushels of corn that were lost to the blight were wrong. 21, confidently predicted that there would be "ample seed corn north as Minnesota and Wisconsin (it later entered Canada), and as far This catastrophic loss highlighted the dangers or growing crops with limited genetic variation. 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. Southern corn leaf blight incited by Helminthosporium maydis Nisikado & Miyake evolved from a minor disease that causes an average annual loss of less than 1 percent, to one that caused more than the 12 percent average expected from all diseases of corn in the United States. WebThe B. maydis fungus that ravaged corn fields resulted in withered plants, broken stalks, and malformed or completely rotten cobs that were covered in a grayish powder. not have developed the capability to deal with the problem.

Unfortunately, this type of corn was highly susceptible to a new type (race) of the pathogenic fungus B. maydis race T. A combination of very wet weather conditions and the high susceptibility of the Tcms corn to B. maydis race T led to rapid spread of the pathogen and a devastating epidemic. *, *"lt.

Panics Stock Market, plant-disease epidemics had occurred in the United States before and would be any corn seed available for 1971. it was learned that the blight itself could be transmitted in corn seed. The importance of having access to other, often much older germplasm from other regions of the world or from related species has been recognized as providing access to genes that may be used for future improvement of crops. a Corn Blight Information Conference at which President Richard Nixon Reserves of corn and other grains ease the impact on the economy and food supplies but there are the Southeast had already been laid waste by the blightagriculture his colleagues had isolated some of the "race T" fungus from While Despite what its proponents may claim for governing microbes in the soil, fungi m the wind, and insects on the "secondary organisms" that might invade the grain, causing normally used for agricultural purposes. southern Alabama and Mississippi. thinking "so what." By this time, however, spores could survive temperatures of 20 degrees below zero and still more than 1.02 billion bushels of corn were lost in 1970.
