The first set of surveys went out to apple industry consultants in July 2008. The results are now available for viewing online here or you can download the report. Another consultant survey went out in January of 2010 asking about practices during the 2009 field season. The results of that survey are now available for viewing by clicking the link to the left.

The following sections present aggregated consultant responses to each question in both table and graph formats. The tables show full or slightly abbreviated question and answer wordings with non-response counts noted. The graphs show generally more abbreviated question and answer wordings with no non-response counts noted. The graphs for leafroller results are accompanied by graphs from parallel codling moth questions for purposes of comparison. Finally, respondent comments that were written into the questionnaires are noted in the footnotes below each table.
