My tomato plants have white,veins on the leaves.

I planted seeds from a tomato I purchased at a vegetable stand,they are growing well. The plants are about 6-8 inches tall and almost ready to plant in the ground. Some of the leaves have a white vein like lines on the leaves. Is it harmful? Is it a disease? I hope you can see this.

    That is Leaf Miner. Remove the affected leaves to control break out. They are difficult to kill because it is IN the leaf and hard to get to with a contact spray, and most systemics are not something you would be able to harvest the fruit afterwards. If it takes over the whole tomato I advise disposing of the entire plant in a plastic bag so that you don't have them spread to other plants in your landscape or garden.

    Thank you,Donna. How can I prevent this? I still have seeds I wanted to plant next tomato season,would the seeds be effected?

    Not a very good picture but I think you have an infection of Leaf miner. No need to worry about the fruit being contaminated. if it is only a few leaves pinch them off and dispose of them well away from the plants. If it is a major infection then the plant may be too weak to set fruit.
