Hello, I am fairly new to gardening I planted seeds in late june of Tomatos, sweet&purple basil , sweet peppers and jalapenos. Most of the plants are in size right black pots. Ive knoticed tho on a few of my tomato plants there are these "black poop sacks" or eggs. They seem to be killing and suffocateing the leaves. Does anyone know what this is and how to get rid of it

Thankx, Pepper
