My winter squashes got taken out by the early blight - so between the blight and the borers, it's definitely a battle to get some production! I did find a probiotic application called Serenade that allowed me to get production from my tomatoes, though if I'd started earlier in the year I think I could've kept the blight from infecting everything so badly (the application stopped the black spot killing my peppers and has allowed them to continue on in health the rest of the summer).
