It may grow past the damage. Or it may not. I personally would eat the fruit they produce--others may have a different opinion--but the badly damaged ones may not produce fruit or only produce a small amount, and it may be stunted. The brown spot on the tomato in the first picture looks like damage from rubbing against the cage. Such damage is no big deal unless a mold or something takes the opportunity to start rotting the fruit or it attracts the attention of a pest. EDIT: For future, maybe you can put your plants somewhere else on your property. If not, maybe you can talk to your neighbor and come to some kind of agreement or you can offer to pull his weeds by hand/hire a neighborhood kid to pull his weeds by hand or something, depending on what problem he's trying to solve.

Bleu_Maples, I'm having the same thing with my new bougies (one of them in particular is more delicious than the others for some reason). Been spraying BT once a week and leaves are still disappearing as soon as they sprout. So, you have my empathy! I can't even find any loopers at night - they're so well camoflaged. Took me a long time to find one, and it was only 1/8" long! (hanging from a thread). Argh! I don't have any other suspects though.

Picture?

Your irises look great! What I see is a little leaf spot.. Not a lot and not enough to worry about. Just take your clippers and cut back the fans that have the spots if you want to. . Leaf spot lives in the soil.. Hot wet humid conditions is what brings it on.. It will not hurt your irises it will just make them ugly.. The outer leaves also usually brown and die back this time of year as well.. You can treat with a fungicide but its not necessary.
