Several Chicago Board of Trade corn contracts fell their 20-cent trading limit late on Wednesday as the US stock market fell for a sixth day and recession fears intensified, traders said. March corn dropped 20 cents to $4.69 a bushel.
"It would be pretty hard to find anything other than a lower call in this environment," a trader said. Corn continues to find underpinning from brisk demand from the livestock feeding, ethanol and export sectors. Export activity on Wednesday included news South Korea bought 220,000 tonnes of corn, traders in Seoul said on Wednesday.
