Cover of the Field Guide to Pests, Beneficials, Diseases and Disorders of Vegetables in northern Australia
This field guide provides easy and quick access to text and images to assist with the identification of pests and disease symptoms in the field. Correct identification of pests, beneficials, diseases and disorders is important in helping to minimise crop damage and when considering management options. The guide provides descriptions, life cycles and biology, monitoring and pest management.
This field guide is an invaluable resource for primary producers, researchers, extension staff and students. It is available in both English and Vietnamese printed versions or can be downloaded below.

About the Field Guide
This publication is the first comprehensive field guide to pests, beneficials, diseases and disorders of commercially grown vegetables in the Northern Territory. The information has been derived from more than 20 years research and extension experience with commercial vegetable crops by staff of Entomology, Plant Pathology and Horticulture, within the Plant Industries Group, Northern Territory Department of Primary Industry and Fisheries. The vegetable field guide is a useful resource for primary producers, researchers, extension staff and students.
The format of the book has been designed to provide easy and quick access to assist in the recognition of pests, diseases or symptoms in the field. Each opening includes text on the left page and photographs on the right page. The tabs along the right edge are labelled and colour-coded, making it easier to navigate.
Due to regular updates and changes in the recommendations of pesticides, specific products have not been listed. However, growers are encouraged to contact Department staff if they require assistance with pest or disease management.
Information regarding pesticide registrations is available from the Australian Pesticides and Veterinary Medicines Authority (APVMA) website.
A comprehensive Agvet chemical database is available free online from Infopest which is owned and managed by Growcom.
Monitoring and Integrated Pest Management (IPM)
Growers are encouraged to use this guide as a resource to assist in the identification of pests and their natural enemies as well as diseases and disorders when monitoring vegetable crops. Correct identification of pests and diseases is important when considering management options. Integrated pest management (IPM) is the management of pest populations using all relevant control practices in a complementary manner, so that the pest will be maintained below the economic injury level and adverse effects to the environment will be minimal. When diseases are incorporated, IPM is referred to as integrated pest and disease management (IPDM).
The majority of vegetables are grown over the ‘dry season’ (May to September) and many pests and diseases are suited to the dry and warm conditions with mean temperatures in the range of 15-36°C (for the Darwin area). The ‘build-up’ to the wet season starts in September and higher temperatures and humidity is generally experienced. Most of the rainfall occurs in the ‘wet season’ between October to April.
This guide provides descriptions, life cycles and biology along with colour photographs to help recognise and distinguish pests from beneficials (which includes natural enemies that attack pests as well as pollinators). Since beneficials help regulate the levels of pests, it is important to monitor pest numbers to assess the level of natural control by predators or parasites before considering other pest management options. Regular monitoring of the crop will assist in the detection of pests and diseases, as well as providing an indication of the change in populations or spread of symptoms.
