Unexplained Rapid Leaf Wilt and Burn

During the morning of August 2nd (5-days ago) leaves were seen wilting/drooping at the margins. Misters were put on “just to see what would happen” and in short there was no visual change. By the end of the day the edges were starting to get dry and by the next morning there was clearly evident burn to the leaves.

The evening the first wilting was noticed, a phosphite fungicide was applied and even though in the morning the wilted portions were burned the rate of progression seemed to have stopped. Now, this did not last forever but progression of the burning has been much slower than expected considering the speed the initial progression only took hours to spread.

At the moment it seems the issue has the rate of spreading characteristics of a phytopthora but has visual signs of Verticillium so it is a bit perplexing at the moment to what is exactly going on.

For those wondering the pumpkin was not measured today, but here at the August 1st numbers and based on the visual diagnosis of the plant, and additional growth will be a bonus…
