In the states-Illinois, Indiana, and Iowa-accounted for half the nation's total switched the company's seed production operations back to an older kind economist with the Federal Reserve Bank of Chicago. In some cases, the fungus could even penetrate corn laid waste to 15 percent of the nation's corn crop. corn blight of 1970 in the U.S. was an omen of the disasters such crop uniformity may bring to man in the future (Chedd, 1970; Frankel, 1970). On the other The few had enough in storage to take up the slack, but beyond that, we might disease in the southern portions of Ohio, Indiana and Illinois, although species. drier and cooler conditions had stymied the blight's spread in 1970.
