Diseased Celery plants

Question

I have a few celery plants and the leaves started to curl up and now the leaves have some white parts. They have stopped growing so I would like to know what I can treat them with to prevent this from recurring. Down by the roots seems to be light brown and the stems are soft.

Answer 1

It could possibly be Apium Virus Y. There is no cure for this. Here is more information on it:
