CHAMPAIGN, Ill. — Illinois farmers launched a new public relations campaign Tuesday to improve their image after research showed that consumers like farmers but have doubts about modern farming methods. Groups representing corn, soybean and livestock farmers announced the campaign at the Illinois State Fair. Representatives said they're particularly concerned about the effect movies such as "King Corn" And "Food, Inc." – both critical of large-scale farming practices – on public perceptions about food safety and environmental damage to land and water. "Some folks are trying to discredit agriculture," said Donna Jeschke, 57, whose family grows corn and soybeans in Mazon in northeastern Illinois.
