  • July 27 tobacco update 07/27/2010
    Since last week there have been some changes to the tobacco fields in some areas. There continues to be NO KNOWN blue mold in Ohio or Kentucky. I have seen some other fields that have serious disease pressure with both black shank and fusarium wilt in the area. The biggest problem for some growers in the last week was the combination of heavy rain that ponded in fields and the following days that consisted of sunny conditions with temperatures above 90. This combination causes the plants to basically drown and scald down. Some plants are completely lost and some are stressed severely. Both cases cause significant yield loss for the grower. Most of the damaged crop is in the southern part of Brown Co. I know the heaviest of the rain was in the southern part of the Ohio Counties that border the Ohio River, but the reports indicate that it was even worse in Mason, Fleming and Lewis Counties in Kentucky.
