Just found this on field pumpkins. The reason I know it is Angular leaf spot is that I had pumpkins tested by local University. Any one out there have any experience controlling this bacteria? I know it can spread very quickly by rain, leaves touching, and human contact with the pumpkins. Any thing out there that can help control this? I am already using copper. Thanks to anyone who replies.

It tends not to be a serious problem in this area but Mancozeb plus copper hydroxide can be effective. You want to make sure the tank mix has a pH greater than 6.5 to avoid damage to the leaves.
