Chemical management of leafminer

Leafminers are difficult to control because the female fly lays eggs below the leaf surface. It means that the larvae develop inside the leaf, where they cannot be reached by insecticides that depend on contact. It is important to target larvae for control as they cause the most damage. They are also more susceptible to insecticides than eggs and less mobile than adults.

Particularly when using systemic insecticides, it is important to observe withholding periods to ensure that residues don’t remain in harvested produce.

The table provides a list of permits approved by the Australian Pesticides and Veterinary Medicines Authority (APVMA), to allow management of leafminers in some crops. The list below will be updated as more permits or registered products become available.

Note: many permits are approved for crop groups (eg leafy vegetables or bulb vegetables). Specific crops covered by each crop group description can be checked at https://apvma.gov.au/crop-groups
