This report is based on data gathered with the assistance of the membership of Cotton Consultants Australia Inc. (CCA) and covers all major cotton growing regions in Australia. The data analysed are drawn from a sample of 110 paired comparisons oflngard and conventional cotton crops. The sample draws on data from 7,634 ha of Ingard cotton, which represents approximately 9% of the 85,000 ha of transgenic cotton grown in 1998/99.
