* DeKalb Genetics Corp.’s fiscal third-quarter earnings fell 79%, worse than expected, as higher production costs at the second-largest U.S. seed company undermined revenue and market share gains. DeKalb said net income fell to $2.8 million, or 8 cents a diluted share, in the quarter ended May 31 from $13.1 million, or 36 cents, in the year-ago period. Revenue rose 23% to $219.9 million from $178.6 million. The earnings come about two months after St. Louis-based Monsanto Co. agreed to buy the 60% of DeKalb it doesn’t already own for $2.3 billion, or $100 a share. Results were far lower than the 36 cents expected by analysts.
