Talkback: A good year for tomato crops

Hi Pippa,

I've also had a continuous supply of both ailsa craig and gold sunrise from my greenhouse grown plants. Until recently they've been very healthy but I've noticed several damaged, hole ridden leaves, and some bright green caterpillars with a yellowish streak which i gather are the culprits? I wonder which type of butterfly may have sneaked thought the vent, whose offspring are busy destroying my lovely tomatoes?!

    Those are the caterpillars of the Tomato moth.  The full name is Bright-line Brown-eye (Lacanobia oleracea.)  Both the moth and the caterpillars are most active at night.  The caterpillars are very good at hiding - check along the stems and any supports, twine etc, especially where any vertical sections are covered by a leaf.  If you go out during the night and have good hearing, you can actually track them down by following the munching sounds! image

    A trowel in the hand is worth a thousand lost under a bush.
