Tip: When considering your order please keep in mind that BIONET is put directly on the seed bed. The plants will push the netting up. Bionet Garden Sheets are complete with hemming on all sides to prevent fraying.
Allow 40/50cm of spare netting on either side for the growth of the crop - e.g. a bed of 1.4m width requires min 2.6m wide netting.
The main threat to carrots is the Carrot Root Fly
Carrot flies lays their eggs between late April and August - two to five 5 times per season. The eggs are placed beside the young carrot. Out of those develop grubs which burrow into the carrots causing tunneling. Sometimes the foliage turns reddish brown. The crop is inedible and will rot in storage.
The carrot fly, Psila Rosae is a serious and widespread pest. Adult flies are about 8mm long, shiny black with reddish head, orange legs and transparent wings. The larvae are 8-10mm long, creamy-white in colour.
What can be done
- Try and sow as lightly as possible to reduce the amount of thinning. Carrot fly operates by smell so be careful not to bruise the foliage. They are most active during the day so do your thinning/harvesting preferably in the evening.
- They aren’t great flyers so a windswept site is ideal.
- Vertical barriers are a good idea for single rows of carrots as the fly doesn’t travel more than 40cms above the ground. However gusts can carry them over the barrier.
- Covers are very effective as the carrot fly is prevented from placing the eggs beside the carrots.
- Mulching with grass cuttings can make it harder for the female flies to lay their eggs in cracks in the soil.
- Never leave infected carrots in the soil overwinter as the pest can live on over the winter ready for your next sowing of carrots.
- Avoid growing related plants like parsnips and celery near carrots, as they also attract carrot fly.
- Crop Rotation will also help to keep the problem under control.
