Do cucumber plants help protect tomato plants from blight?

resonance: 25.7% from: robg

I'm not really sure of the answer right now but I noticed that of all the tomato plants in my garden, the one being used as a scaffold by a neighboring cucumber plant seems better protected from blight. That is, the cucumber leaves seems to be shielding the tomato plant but while allowing for healthy growth from both. I can make up a story about how the cucumber plant blocks the blight spores from attaching to the tomato plant. And since those spores can harm the cucumber plant they might just dry out before they can reproduce. I'm not sure if that's correct though. Next year I'd like to try planting cucumber plants in between some tomato plants to test this idea further.
