Pinto Beans: Dry, but not Desperate

 The Pinto Beans are growing, but the field is dry on the surface.
 They have started vining.
When I dig down about an inch in this field, I feel moisture. There is a theory floating around that the crop roots have grown down deep this season in our area. 
We had an early Spring that became dry causing the crops to root well. We are hoping that the time we have spent Deep Ripping to relieve soil compaction will help the pinto beans reach moisture.
I hope the theory is truth. When I look out at a pinto bean field I see food. The world needs this crop. 
Another field of pinto beans, on lighter soil, missed our last shot of rain. 
However, the pinto beans do not appear to be suffering. 
There is moisture in the ground. 
It is hot in GriggsDakota, but today was not windy. 
That allows the leaf canopy to keep the blossoms cool. The plant is able to stay hydrated as long as it can reach moisture with it's roots. When it is windy and hot, the pinto bean plant cannot keep up as it draws moisture into itself and the plants suffer, which decreases the yield potential of the bean crop. 
 You can see that in this field, the blossoms are producing pinto beans.
 We have a decision to make. 
Do we apply fungicide and assume these pinto beans will need it? Do we keep that cost of the fungicide application in our pockets, assuming that this crop will be too dry to receive any benefit?
We are doing a rain dance in GriggsDakota.
