  • Yellowing leaves on cucumber plant - is this Mosaic virus?

    The lower leaves on both my cucumber plants are yellowing fast (lots of yellow spots spreading until they cover the whole leaf & now some grey patches appearing).

    They are in a greenhouse in grow bags, plants seem to still be growing well with lots of flowers with the beginnings of a few cucumbers.

    Any ideas what the cause is, could this be the dreaded mosaic virus?

    Photos should be attached.


    thanks

    It looks more like scorch to me, and the leaves higher up the plant look healthy.

      The spots on pic three look to regular for sun scald, have you had a greenfly attack?

      For a start I would cut the lower leaves off and destroy them, then wait and see. Make sure you wash your hands thoroughly after handling the leaves.

        Not Mosaic virus. As RL said scorch...don't water the leaves or while sun is on them.

          Powdery mildew is very common on cucs, I'm not saying that is what yours have but may be just an option to consider.
