Post category: Celery fly

 

The maggot of this fly is so tiny that it can tunnel between the upper and lower surfaces of celery leaves, earning for itself the alternative name of celery leaf miner. It sometimes attacks parsnips leaves. If the attack comes early and in numbers, the foliage can be destroyed and growth stopped. A late attack only damages some leaves and is of no great concern.

If the attack is light – just a couple of mines per plant – it is possible to pick off parts of the affected leaves. If this is not possible Hygeia Greenfly Spray or Bio Longlast can be used.
