I have updated my June 23rd post with additional information regarding curly top and tomatoes. But curly top also infects potatoes as well as other garden plants. Indeed, variety seems to be important in fighting curly top.
I have two rows of potatoes, planted from seed potatoes. I have observed that the red potatoes are virtually unaffected by curly top, but the white (actually gold) potatoes are largely infected and dying. I am harvesting some nice "new" potatoes from these dying plants, but fear I will not get many mature ones.
It is also my observation, to date, that Crenshaw Melons are not affected by curly top, but Ambrosia Cantaloupes are, somewhat. The effect on Ambrosia is not significant, but has taken two of my plants.
In my garden, this year, my Crookneck Summer Squash was completely taken by curly top, but my Zucchini is unaffected.
My Spaghetti Squash, Big Max Pumpkin, and Toquer Squash are, so far, unaffected by curly top.
The cucumber I planted early, all died, presumably from curly top, but cucumber I planted later, are so far unaffected, and are thriving.
