First I thought early blight, now...
I am thinking perhaps this is the work of insects? I've noticed an abundance of white mites on some of the branches and leaves but never had this kind of damage and never thought they could cause this. Overall, as the pic shows, it first looks like rain damage and burning of spots on the leaves. But then it progresses to yellow, holes, etc. And eventually the whole branch dies and withers up. This is taking place on the lower plant, but slowly working upwards.
These are hybrid plants, btw. Every year we get a touch of blight late in the season, usually not this early. I just cleaned the plants up as much as possible and am going to spray with daconil in a few just in case it is a disease.
My peppers look a little sick as well (leaves yellowing and dropping at the lower levels, moving up), which is rare for my area.
Thank you for your thoughts!
