This field guide is designed to assist growers, workers, students, extension officers and farm advisers to identify insect or mite pests, beneficial organisms (‘beneficials’), diseases and disorders in tomatoes, capsicums, chillies and eggplants. It is intended to be a tool for integrated pest management. The front section of the guide has a general introduction to pest management, and some useful summary agronomy tables. The rest of the guide is devoted to insect and mite pests, beneficials, diseases or disorders that may be found in these crops in either Australia or Cambodia. It also includes a diagnostic tool to help identify crop problems.
