Attached are photos of three tomato leaves, one basil and one oregano. Please look at the these and tell what is wrong with them. Is it a fungus? Do all three have the same thing? Also, last night I cut them from their plants and put them a plastic bag and sealed. This morning when I opened the bag, I found the tiny brown”things.” I don’t know what plant they came from but I wanted you to see them. There are still healthy looking leaves on each of these plants. The basil and oregano are in the same planter. Also, I notice what appears to be tiny gnats on the pots.
Please tell me what is wrong with these plants and what I can do.
I am sorry, but I did not receive the photo of your three tomato leaves so I am unable to help you identify what is ailing them.
The tiny brown things - it looks a lot like excrement, perhaps from a tiny caterpillar - possibly baby hornworms. More information on hornworms can be found here:
You mentioned gnats on the pots - these are probably fungus gnats. You can read more about fungus gnats and a course of treatment in the following article:
