Revision: Data was revised 08/2004. The only changes made were to Yield Loss (%). This data was corrected, with the only major discrepancies occurring in years 1996-1999.
Revision: Data was revised 03/2009. The only changes made were to Lint Price ($/lb) and Statewide Economic Loss (for yield; $). This data was corrected, with the only discrepancies occurring in the year 2006.
Revision: Data was revised 05/2010. Changes were made to Insecticide Applications (No./A) and Total Acres to correct data entry errors. The only discrepancies occured in the 2008 data for these two variables and was posted on the internet from 2/16/2010 to 04/29/2010.
