Commercial cotton crops throughout NSW have been surveyed in November and March of each season since 1983 to determine disease distribution, incidence and severity. Cropping history, field preparation, seed rate, plant stand and the amount of crop residue remaining from the previous cotton crop have been recorded for each field inspected. Between 80 and 100 commercial fields have been inspected in each survey. The results of these surveys provide a basis for prioritising research efforts and give an indication of the impact of farm management practices on disease incidence and severity.
