The Q&A Archives: Tomato Plant

Question: Some leaves on my tomato plant have what looks like a track. It lokks similar to a slug track. How do I get rid of it or control it?

Answer: Are you seeing what look line squiggly white lines in the leaves? If so, there are leaf miners at work. An adult sawfly lays an egg just under the upper surface of the leaf and the egg hatches into a larvae. The little worm feeds on the tissues between the upper and lower leaf surfaces then exits the leaf and pupates in the soil. There's not much you can do in terms of control and aside from making the leaves look unattractive, the feeding won't hurt the leaves or your plants.
