You clearly know nothing about this stuff to say the things you do, which is fine, if you don't deal with it good for you but it's real.  There are diseases and illnesses and always will be because that's the real world.  You talk about something like you speak from a higher level of understanding but what knowledge have you ever brought to a conversation that brings a solution?  I missed that post if it's out there because I only remember all the holier than thou condemnation posts to those that do use it. 

Spraying is the solution we have, there is no soil health resolution to this problem.  If there is, bottle it and sell it but saying it exists because you 'think' it does doesn't make it so.  If the universities had the answer, they'd bottle and sell it too, but wait, there isn't one.  So, since the solution today is spraying, we spray and we spray before the disease sets in.  And since fungicides don't last for 3 months but the disease sure can, we spray again to keep the protection going.  How about building a better fungicide to last 3 months and not 2-3 weeks?  Probably some kick butt dollars to be had with that!  Again, solution???? 

When was the last time SR blew up like this?  Ever?  Sometimes things just come together, for the bad.  As far as resistance to SR, not sure but since it comes in from the south and doesn't overwinter here my guess is it'll take a while.  In the meantime, i'm spraying to protect bushels and while grumbling about the check(s), I sleep like a baby knowing I did it.  I sell bushels to make dollars, it's called farming. Soil health should equal something that relates to my business, more bushels, less costs, something, not a set of new cloths for the emperor.
