COLUMBUS, Ind. (AP) _ Indiana farmers say they're seeing great potential for their crops this year following the 2012 drought, but many are still keeping close watch for signs of disease.
 
  Purdue University pathologist Kiersten Wise reported this month that three diseases have started appearing in some Indiana cornfields. They include gray leaf spot, northern corn leaf blight and Goss' wilt.
 
  Farmer Evan Clouse tells The Republic he is keeping an eye on the weather and watching for disease. He's had a specialist check his crop and says he'll use a fungicide if needed.
 
  Strong corn and soybean yields this year could help farmers rebound. Last year's corn yields were down 55 percent from 2009 because of the prolonged drought.
