Pest and disease issues have been minimal in Mississippi’s corn crop this year, but there has been an unusual amount of heat stress. (Josh Tilley)Mississippi’s corn crop is looking good this year, and harvest began in July for what was one of the earliest planted corn crops in state history. “Most of our corn crop was planted in the last 10 days of March,” Larson said. Tim Fondren, Extension agent in Leflore County, said the corn crop in his area looks good. “High moisture harvest began the middle of July, and traditional moist corn harvest will begin in two to three weeks,” Fondren said.
