Carrot rust fly (Psila rosa)

Symptoms

• The larvae mine in the roots, causing holes that are subject to rot by secondary organisms. Heavy maggot feeding is indicated by drooping, discolored foliage.
• If the roots are severely injured the leaves become rusty brown or even dry.

Management

• Deep ploughing
• Crop rotation
• Destruction of wild hosts
• Place yellow sticky trap to monitor the adult flies.
• Apply neem cake in the soil.
