Now, the bad news.  I'm having a lot more trouble this year with bugs and disease than I expected, based on my experience with a community garden plot last year.  Some of the problems I've diagnosed already, others I'm stumped.  Any help would be appreciated!

First, the tomatoes:

I'm having trouble with two viral infections right now.  Curly Top and Fusarium Wilt.  They're mostly affecting the non-resistant varieties, but even some hybrids are suffering. 

This plant has Tomato Hornback caterpillar damage and Curly Top:

Here's a close up of Curly Top damage.  The plants are stunted and not flowering. 

The only solution for these infections is removal of the plant.  Ugh.  It's almost half of my 20 plants!  Some of the heirlooms are also showing signs of Fusarium Wilt, which, according to my references, may require soil solarization to prevent this from happening next year too.  It will be a much smaller tomato yield than I hoped for this year, although I suppose with my late start and early growth issues, can't be a total surprise.

My trellised cantaloupes having symptoms of powdery mildew.  I treated that this morning with a mixture of baking soda and dish soap dissolved in water.  My references say that it's a good organic fungicide and fungal preventative.  Hopefully it works!  Those cantaloupes are looking wonderful.  

Some of my peppers are having something like blossom-end rot on them, although my references describe it as "water soaked, sunken areas."  Although the fruit tips are brown, shrunken, and, and sunken, they don't seem "water-soaked."  Does this look like typical blossom end rot?  It's spread across multiple varieties, all over the garden. 

My green bell pepper has an odd spot on it.  It's dry and paper thin where you see the white in this picture.  Any ideas?

And last major issue:  What the heck are these bugs?  They're exclusively on my eggplants.  They look way too big to be aphids, and they seem to have two forms, the green stem huggers, and then these black and green shell-like leaf-dwellers.  They like to congregate in the crevices between blossoms and the blossom clusters wilt and fall off.
