What could be causing holes in tomato leaves?

Answer by  Requin (290)

Check your plants for tomato worms. They are large, thick green worms that look like caterpillars and they will chew holes in your plant's leaves.

This is most likely caused by insects eating the leaves. You need to put out some pesticide. SevinDust is a good choice for this problem.

It could be caused by tomato hornworms, ants or beetles. It also could be a fungal infection from over watering. Something with bacillius thuringiensis in it will get rid of worms or insects. Neem oil based peticides work for insects. Spraying tomato plants with water may work for hornworms. They will start wiggling and you can pick them off.

It's most likely bugs and caterpillars that are causing the holes in the tomato leaves. They like to chew little holes. The types of bugs and caterpillars are based on which area you live in. There are insecticides that you can spray on the plants to keep the bugs off.
