I'm starting to see brown spots on the leaves of a couple of my pumpkin and squash plants. From the pictures I'm seeing online, it looks like Alternaria to me, but I'm not too sure. Can anyone confirm this? How aggressive is it in spreading? I planted all my squash/cucumbers/melons in the same area of my garden and ended up planting them a bit too close together. I'm worried that I'm going to end up losing everything. Should I cut off the leaves with the worst spotting? Aside from Neem, are there any other organic options for treating this?

Thanks,
Eric
