The answer is Rotenone specifically lists the tortoise beetle - I'll give it a try soon.

How many do you have? If only a few, physically remove, squish, or flick into soapy water and skip the rotenone.

I have a pest that's similar but not the same. Zone 5, north of Toronto. Starte with yellow leaves, then holes in leaves, then holes in green leaves, then lower leaves die and progresses up the plant. In patio pots, Sunrise variety. Second yeaer of this in my patio pots. I've seardhed Google images and all over Garden Web and haven't seen this pest. Plese help! I miss having good tomatoes. They still grow but don't mature properly and are very bland tasting. Anything you guys can tell me will help! TIA
