Introduction
The following disease information is an output of the Improved IPM systems in the Australian sweet corn industry (VG05035). This project aims to improve Integrated Pest Management (IPM) systems currently used in the Australian sweet corn industry to manage a range of 'secondary pests,' whilst maintaining or improving heliothis management. Further sweet corn information is available on the sweet corn home page.
