Carrot Root Fly
Carrot Root Fly
The Carrot Root Fly (Psila rosae) can be a severe pest to Carrot crops. Adult Carrot Root Fly emerge from pupae in the soil from April and will then lay fresh eggs. Those eggs will hatch into creamy coloured larvae after about 7 days, depending on the weather. The larvae will move through the soil to the Carrot plants and start feeding on the roots, eventually burrowing into the Carrot roots forming mines. The first symptoms are a reddening of the Carrot leaves, which start to wilt. The larvae will leave carrots with extensive damage and disfiguration.
Nematodes are a natural pest control which require warm soil conditions to be active. There are normally two generations of Carrot Root fly a year. For best results apply Carrot Root Fly Killer nematodes from May to June and August to October.
The nematodes are supplied in a gel formulation which keeps them of high quality in storage and delivery. Suitable for storage in the fridge for up to 6 weeks if unopened.
PLEASE NOTE - As these are live creatures, they are bred in batches to be as fresh as possible and so your nematodes will be prepared to order and despatched in approx 5 working days depending on demand.
