As reports of Goss's wilt continue to expand north and east in corn-growing areas both in the U.S. and now in parts of Canada, growers need to assess its potential impact to help choose resistant lines for next season where the disease is present, say experts at Pioneer Hi-Bred, a DuPont business. These assessments will guide growers' seed decisions for next year and help minimize the potential for yield loss.
"The disease recently has been reported in Colorado, Nebraska, the Dakotas, Manitoba, Minnesota, Iowa, Wisconsin, Illinois and Indiana," said Scott Heuchelin, Pioneer research scientist and field pathologist. "It typically occurs as the result of hail events and storms. When plants sustain abrasion injuries from hail or wind, Goss's wilt bacterium can infect the leaves where they have been damaged. If growers have had hail damage, they should be on alert."
